River Ju (Hubei)
The Ju River in North China Plain is a major river in the Beijing and Tianjin vicinities. It is a part of Hai River's watershed system. In 354 BCE (Warring States period of Zhou dynasty), State of Yan defeated State of Qi in a battle by this river. In Han dynasty, the original channel of Ju River was widened by Emperor Xian so that it became a navigable river and a major military supply line to the northeast frontier. The total length of Ju River is , of it in the Pinggu District of Beijing. Before paved roads were constructed in 1930s, this river was the only transportation route to and from the remote Pinggu region. The river was polluted by industrial wastewater Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product.

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia.

Industrial Wastewater Treatment
Industrial wastewater treatment describes the processes used for treating wastewater that is produced by industries as an undesirable by-product. After treatment, the treated industrial wastewater (or effluent) may be reused or released to a sanitary sewer or to a surface water in the environment. Some industrial facilities generate wastewater that can be treated in sewage treatment plants. Most industrial processes, such as petroleum refineries, chemical and petrochemical plants have their own specialized facilities to treat their wastewaters so that the pollutant concentrations in the treated wastewater comply with the regulations regarding disposal of wastewaters into sewers or into rivers, lakes or oceans. This applies to industries that generate wastewater with high concentrations of organic matter (e.g. oil and grease), toxic pollutants (e.g. heavy metals, volatile organic compounds) or nutrients such as ammonia. Some industries install a pre-treatment system to remove som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emperor Xian Of Han
Emperor Xian of Han (2 April 181 – 21 April 234), personal name Liu Xie (劉協), courtesy name Bohe, was the 14th and last emperor of the Eastern Han dynasty in China. He reigned from 28 September 189 until 11 December 220. Liu Xie was a son of Liu Hong (Emperor Ling) and was a younger half-brother of his predecessor, Liu Bian (Emperor Shao). In 189, at the age of eight, he became emperor after the warlord Dong Zhuo, who had seized control of the Han central government, deposed Emperor Shao and replaced him with Liu Xie. The newly enthroned Liu Xie, historically known as Emperor Xian, was in fact a puppet ruler under Dong Zhuo's control. In 190, when a coalition of regional warlords launched a punitive campaign against Dong Zhuo in the name of freeing Emperor Xian, Dong Zhuo ordered the destruction of the imperial capital, Luoyang, and forcefully relocated the imperial capital along with its residents to Chang'an. After Dong Zhuo's assassination in 192, Emperor Xian fell u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Han Dynasty
The Han dynasty (, ; ) was an imperial dynasty of China (202 BC – 9 AD, 25–220 AD), established by Liu Bang (Emperor Gao) and ruled by the House of Liu. The dynasty was preceded by the short-lived Qin dynasty (221–207 BC) and a warring interregnum known as the ChuHan contention (206–202 BC), and it was succeeded by the Three Kingdoms period (220–280 AD). The dynasty was briefly interrupted by the Xin dynasty (9–23 AD) established by usurping regent Wang Mang, and is thus separated into two periods—the Western Han (202 BC – 9 AD) and the Eastern Han (25–220 AD). Spanning over four centuries, the Han dynasty is considered a golden age in Chinese history, and it has influenced the identity of the Chinese civilization ever since. Modern China's majority ethnic group refers to themselves as the "Han people", the Sinitic language is known as "Han language", and the written Chinese is referred to as "Han characters". The emperor was at the pinnacle of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Qi (state)
Qi, or Ch'i in Wade–Giles romanization, was a state of the Zhou dynasty-era in ancient China, variously reckoned as a march, duchy, and independent kingdom. Its capital was Linzi, located in present-day Shandong. Qi was founded shortly after the Zhou overthrow of Shang in the 11th centuryBC. Its first marquis was Jiang Ziya, minister of King Wen and a legendary figure in Chinese culture. His family ruled Qi for several centuries before it was replaced by the Tian family in 386BC. In 221BC, Qi was the final major state annexed by Qin during its unification of China. History Foundation During the Zhou conquest of Shang, Jiang Ziya, a native of Ju County served as the chief minister to King Wu. After King Wu's death, Ziya remained loyal to the Duke of Zhou during the Three Guards' failed rebellion against his regency. The Shang prince Wu Geng had joined the revolt along with the Dongyi states of Yan, Xu, and Pugu. These were suppressed by 1039 BC and Jiang w ...

Yan (state)
Yan (; Old Chinese pronunciation: ''*'') was an ancient Chinese state during the Zhou dynasty. Its capital was Ji (later known as Yanjing and now Beijing). During the Warring States period, the court was also moved to another capital at Xiadu at times. The history of Yan began in the Western Zhou in the early first millennium BC. After the authority of the Zhou king declined during the Spring and Autumn period in the 8th century BC, Yan survived and became one of the strongest states in China. During the Warring States period from the 5th to 3rd centuries BC, Yan was one of the last states to be conquered by the armies of Qin Shihuang: Yan fell in 222 BC, the year before the declaration of the Qin Empire. Yan experienced a brief period of independence after the collapse of the Qin dynasty in 207 BC, but it was eventually absorbed by the victorious Han. During its height, Yan stretched from the Yellow River (at the time, the river followed a more northerly course than at prese ...

Zhou Dynasty
The Zhou dynasty ( ; Old Chinese ( B&S): *''tiw'') was a royal dynasty of China that followed the Shang dynasty. Having lasted 789 years, the Zhou dynasty was the longest dynastic regime in Chinese history. The military control of China by the royal house, surnamed Ji, lasted initially from 1046 until 771 BC for a period known as the Western Zhou, and the political sphere of influence it created continued well into the Eastern Zhou period for another 500 years. The establishment date of 1046 BC is supported by the Xia–Shang–Zhou Chronology Project and David Pankenier, but David Nivison and Edward L. Shaughnessy date the establishment to 1045 BC. During the Zhou dynasty, centralized power decreased throughout the Spring and Autumn period until the Warring States period in the last two centuries of the dynasty. In the latter period, the Zhou court had little control over its constituent states that were at war with each other until the Qin state consolidated power and forme ...

Warring States Period
The Warring States period () was an era in History of China#Ancient China, ancient Chinese history characterized by warfare, as well as bureaucratic and military reforms and consolidation. It followed the Spring and Autumn period and concluded with the Qin's wars of unification, Qin wars of conquest that saw the annexation of all other contender states, which ultimately led to the Qin (state), Qin state's victory in 221 BC as the first unified History of China#Imperial China, Chinese empire, known as the Qin dynasty. Although different scholars point toward different dates ranging from 481 BC to 403 BC as the true beginning of the Warring States, Sima Qian's choice of 475 BC is the most often cited. The Warring States era also overlaps with the second half of the Eastern Zhou Period, Eastern Zhou dynasty, though the Chinese sovereign, known as the king of Zhou, ruled merely as a figurehead and served as a backdrop against the machinations of the warring states.

Hai River
The Hai River (海河, lit. "Sea River"), also known as the Peiho, ("White River"), or Hai Ho, is a Chinese river connecting Beijing to Tianjin and the Bohai Sea. The Hai River at Tianjin is formed by the confluence of five watercourses: the Southern Canal, Ziya River, Daqing River, Yongding River, and the Northern Canal. The southern and northern canals are parts of the Grand Canal. The Southern Canal is joined by the Wei River at Linqing. The Northern Canal joins with the Bai He (or Chaobai River) at Tongzhou. The Northern Canal (sharing a channel with Bai He) is also the only waterway from the sea to Beijing. Therefore, early Westerners also called the Hai He the Bai He. At Tianjin, through the Grand Canal, the Hai connects with the Yellow and Yangtze rivers. The construction of the Grand Canal greatly altered the rivers of the Hai He basin. Previously, the Wei, Ziya Yongding and Bai Rivers flowed separately to the sea. The Grand Canal cut through the lower reaches of t ...

North China Plain
The North China Plain or Huang-Huai-Hai Plain () is a large-scale downfaulted rift basin formed in the late Paleogene and Neogene and then modified by the deposits of the Yellow River. It is the largest alluvial plain of China. The plain is bordered to the north by the Yanshan Mountains, to the west by the Taihang Mountains, to the south by the Dabie Mountains, and to the east by the Yellow Sea and Bohai Sea. The Yellow River flows through the plain, before its waters empty into the Bohai Sea. The part of the North China Plain around the banks of the middle and lower Yellow River is commonly referred to as the Central Plain (). This portion of the North China Plain formed the cradle of Chinese civilization, and is the region from which the Han Chinese people emerged. Beijing, the capital of China, is located on the northeast edge of the plain, with Tianjin, an important industrial city and commercial port, near its northeast coast.
