The negative effects of wastewater and the issue of freshwater pollution in china
Effects on Aquatic Wildlife The environment is severely damaged in places due to water pollution. These problems include 1 the environment, 2 impacts on society, 3 economic concerns in building the project and 4 the agricultural economic effects on the lack of wastewater treatment facilities within China.
China suffers from widespread water pollution after years of unbridled economic growth. Municipal and industrial waters contain chemicals, organic, and thermal wastes, and sewage consisting of human wastes.
Irrigation and Agriculture Not only does the city of Tianjin use the water system for irrigation; Chao Lake also uses the contaminated wastewater as a source for irrigation. The nationwide standards for the treatment of sewage are also far from sufficient.
Air pollution in china
This is the easiest way to treat metal containing wastewater because it removes most of the metal at the source of discharge. However, many of the farmlands requires the uses of some type of pesticide to maintain their cropland, effluent wastes containing pesticides pouring into the streams, lakes, and rivers eventually seeps into the groundwater Benarde, Picture 2. There are some 5, separate industrial units in Tianjin City. There are potential political, economical and technical issues to consider. Since Xian City has a population of 2. Ecological Applications 6 December 20, : 4. One type of wastewater treatment project is the reed-bed system. Finally, water carries pollution across boundaries: therefore, different jurisdictions often with competing interests regularly have to cooperate to control pollution in a given river or lake.
It is vital that an acceptable solution is found to treat this wastewater before the ground water and surrounding environment is severely polluted as well.
However, water is neither produced nor destroyed and the amount of vital usable water is quite limited. Since the reeds can be harvested each year along with providing a decent wildlife habitat, this can improve the quality of the ecosystem.
Industrial water pollution in china
For health reasons, wastewater flowing into the water systems is not healthy for the community. To improve the water quality to a maximum, technical aspects must be reviewed. In recent years, the rapid development of industrial and urban areas, and changes in agricultural practices, have caused damage to the lake. With the on going problem of wastewater pollution in China, this will continue to affect the ecosystem negatively. This treatment plant will contain the following components listed in Table 2. Also, the supply of nitrogen is the factor determining algal growth, which in turn determines the growth conditions for the next link in the chain zooplankton , and results in the growth of higher organisms. The Ministry also maintains a WeChat account, onto which citizens can upload photographs of rivers that they consider excessively polluted; the Ministry promises to respond to such reports and to add the data to the national list of highly polluted rivers. By proposing the projects for wastewater treatment facilities, we can prevent the degradation of the economy by saving the agricultural industry. Companies that are found to violate dumping laws should be subject to legal penalties - such as fines - that are actually enforced. A project was proposed for a new wastewater treatment plant in Xian City. A reverse osmosis system Picture 3 uses a semipermeable membrane to filter the wastewater extensively by removing both inorganic and organic wastes.
Residential demand for water is also projected to increase from 31 billion tons at the same time Brown, et al. Sludge treatment by gravity thickening of the aerobically stabilized sludge.
Farm fertilizer has largely contributed to water contamination. One type of wastewater treatment project is the reed-bed system.
