P'yŏngch'ŏn-guyŏk (Phyongchon District) is one of the 18 '' guyŏk'' (political districts or wards) of P'yŏngyang, North Korea. It is bordered by the Taedong River in the south and the Pothonggang Canal in the north and Potong River in the west, and to the east by Chung-guyŏk, from which it is separated by the yard area of P'yŏngyang railway station. History The name of the district, passed down from the former ''Pyongchon-myon'', means a flat area, which water flows through. It was newly was established as a guyŏk in October 1960 by the P'yŏngyang City People's Committee through a mandate of the Central Committee of the Workers' Party of Korea. In 1963, a part of Pyongchon-dong was separated to form Haeun-dong, a part of Kansong-dong was separated to form Ryukkyo-dong and parts of Puksong-dong and Pongji-dong were split off to form Pongnam-dong and Ansan-dong.

Pyongyang (, , ) is the capital and largest city of North Korea, where it is known as the "Capital of the Revolution". Pyongyang is located on the Taedong River about upstream from its mouth on the Yellow Sea. According to the 2008 population census, it has a population of 3,255,288.

Organic Fertiliser
Organic fertilizers are fertilizers that are naturally produced. Fertilizers are materials that can be added to soil or plants, in order to provide nutrients and sustain growth. Typical organic fertilizers include all animal waste including meat processing waste, manure, slurry, and guano; plus plant based fertilizers such as compost; and biosolids. Inorganic "organic fertilizers" include minerals and ash. The organic-mess refers to the Principles of Organic Agriculture, which determines whether a fertilizer can be used for commercial organic agriculture, not whether the fertilizer consists of organic compounds. Examples and sources The main organic fertilizers are, peat, animal wastes, plant wastes from agriculture, and treated sewage sludge.Heinrich Dittmar, Manfred Drach, Ralf Vosskamp, Martin E.

Fly Ash
Fly ash, flue ash, coal ash, or pulverised fuel ash (in the UK) plurale tantum: coal combustion residuals (CCRs)is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases. Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash. In modern coal-fired power plants, fly ash is generally captured by electrostatic precipitators or other particle filtration equipment before the flue gases reach the chimneys. Together with bottom ash removed from the bottom of the boiler, it is known as coal ash. Depending upon the source and composition of the coal being burned, the components of fly ash vary considerably, but all fly ash includes substantial amounts of silicon dioxide (SiO2) (both amorphous and crystalline), aluminium oxide (Al2O3) and calcium oxide (CaO), the main mineral compounds in coal-bearing rock strata.

Sewage Treatment Plant
Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable for discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges. Sewage contains wastewater from households and businesses and possibly pre-treated industrial wastewater. There are a high number of sewage treatment processes to choose from. These can range from decentralized systems (including on-site treatment systems) to large centralized systems involving a network of pipes and pump stations (called sewerage) which convey the sewage to a treatment plant. For cities that have a combined sewer, the sewers will also carry urban runoff (stormwater) to the sewage treatment plant. Sewage treatment often involves two main stages, called primary and secondary treatment, while advanced treatment also incor ...

Potong River
The Pothong River (Pot'ong River, Potonggang or Potong) is a river in North Korea. It flows through the capital Pyongyang and is a tributary of the Taedong River. There are several bridges across the river in Pyongyang, including one at its mouth called the "Pothong Bridge"; however, the largest is the one known as "Ansan Bridge", , which supports the main east-west divided highway. Prior to 1946, the arable land west of Pyongyang alongside the river (the flood plain), down to where it entered the Taedong River was subject to annual flooding. This area was known as ''Tosongrang''. The farmers there annually rebuilt their homes after the floods subsided, so the construction was, perforce, of a temporary nature, huts and even pit-house A pit-house (or ''pit house'', ''pithouse'') is a house built in the ground and used for shelter. Besides providing shelter from the most extreme of weather conditions, these structures may also be used to store food (just like a pantry, a larde ...

Railway
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facilit ...

The current Minister of Railways is Chang Jun Song. History 1945–1953: Liberation, Partition, and the Korean War The railway lines of North Korea were originally built during the Japanese occupation of Korea by the Chosen Government Railway (''Sentetsu''), the South Manchuria Railway (''Mantetsu'') and various privately owned railway companies such as the Chosen Railway (''Chōtetsu''). At the end of the Pacific War, in the territory of today's North Korea Sentetsu owned of railway, of which was standard gauge, and was narrow gauge; in the same territory, privately owned railway companies owned of rail lines, of which was standard gauge and was narrow gauge.
