Nonpoint source is also called non-specific source, cotton source, mobile source or other water source. Point sources refer to places or areas where nonpoint pollutants are generated through unspecified emissions pathways, such as urban road drainage or agricultural land drainage, unlike those with specific emissions pathways.

Aquaculture aquaculture facilities, golf course facilities, transportation equipment, maintenance or junkyard facilities, concentrated aquatic products simple processing facilities, photograph processing facilities, etc., which have been renamed from `` specific facilities '' to `` other water pollution sources '' under the Water Quality Preservation Act; This includes other facilities such as product yards, product yards, and land quality change areas.

Nonpoint pollutants are mainly pollutants that are discharged along with surface runoff when it rains. Fertilizers, pesticides, soil erosions, barn spills, traffic pollutants, urban dust and garbage, residues of natural animals and plants It refers to water and air pollutants that fall on the ground.

Thus, rainwater discharged, including all pollutants, is in fact the main nonpoint source. Non-point pollutants are usually discharged only when there is a lot of rain, so they have a large difference in daily and seasonal emissions, difficult to predict and quantify, and are affected by weather conditions, geology, and terrain, which are difficult to control artificially. Therefore, emission standards are not systematically set.

As a result of the 'Non-point Pollution Research Service' (June 2000) on the upstream area of Paldang Dam, the main source of water for residents of the Seoul metropolitan area, as of the end of 1999, Pollutant loads generated from point sources such as industrial wastes and livestock wastes were 13,6509 tons per year, which is 80.4%, and 331 393t / year, which was 19.6%.

In addition, the total discharge load (BOD basis) is estimated to reach 44.5% of nonpoint sources, indicating that nonpoint sources have a significant effect on water pollution. The similarities are found in the Geum, Nakdong, and Youngsan rivers. It is estimated to show. Therefore, as the regulations on point sources with regulatory standards have been strengthened and environmental foundations are expanded, the influence of nonpoint sources on water quality will gradually increase.

As a countermeasure to reduce pollution, road drainage in urban areas should be equipped with a reservoir to settle and discharge pollutants caused by the initial rain, and agricultural drainage containing a large amount of fertilizers and pesticides from agricultural land. In order to prevent direct inflow into rivers, reservoirs, wetland purification facilities, and plants should be installed. In addition, it is necessary to reinforce relevant regulations in laws and regulations such as the Water Quality Preservation Act or to enact relevant laws in order to manage them systematically.

Zeolite is a generic term for minerals that are aluminum silicate hydrates of alkali and alkaline earth metals and are colorless or translucent white. It is also called zeolite and has many kinds, but has high water content, common nature of crystal, acid and so on.

A hydrous silicate mineral containing sodium and aluminum. It is colorless or white, glossy in glass, and usually flows from hollow holes or cracks in basalt or tuff. Chabasite and Natrol Knight.

Also called tombstone. Although there are many types, they have a high water content, common properties of crystals, and acid phase. Hardness does not exceed 6, specific gravity is about 2.2. Generally it is colorless transparent or white translucent. It is named because it boils and expands when it is heated by duct.

Most varieties are dissolved in hydrochloric acid, often glued, but few are not dissolved in hydrochloric acid. The main types are the pit, fisheye, cabbage, soda, hydrandite, steel bite, lomonite, and enesite. It is produced in the cavities of the basic igneous rocks such as basalt and tuff, and in the hot pole, and sometimes exists as a secondary mineral in granite and gneiss.

It may also be produced in gold or other veins. The bonds of the atoms are loose in crystal structure, and even though the moisture filling the spaces is released at high heat, the skeleton remains the same, so that other fine particles can be adsorbed. This property is used as an adsorbent and used as a molecular sieve to separate particulates of different sizes.
