Abstract

Phosphorus is an indispensable element of the organism. Abundance or shortage of phosphorus element, the pros and cons of the environment will directly affect the growth and development of all organisms, including humans. Life, the existence of various forms of phosphorus. The most common, such a large number of people to use a phosphorus-containing detergent and phosphate; industrial with phosphate ores system taken on the the element phosphorus as well as a series of phosphorus compound; phosphate generated in the metal surface treatment process wastewater, etc.. Use and emissions of a large number of phosphorus compounds, and serious damage to the natural cycle of phosphorus and social metabolism, causing environmental pollution, hydrosphere and biosphere, the most obvious effects of phosphorus. Current excess phosphorus concentration of water impact performance eutrophication and algae blooms phenomenon, and its essence is the oxygen consumption of organic matter and nitrogen, the effects of the ecological environment of the phosphorus compounds. They have become the hot spot of China's environmental protection and even control is very difficult governance issues. Studies have shown that phosphorus is the main controlling factor causing eutrophication. Currently, the major rivers in the country appear in the part of the river eutrophication phenomenon Huangpu River Basin, the Qiantang River Basin, the Yangtze River, the Pearl River in Guangzhou and other. Therefore, the combination of the natural geographical features and industrial structure of the basin-specific monitoring the main source of phosphorus pollution in the watershed, and research in line with the actual situation of phosphorus pollution monitoring and management measures, remediation has practical significance. Wuyi in Jinhua River upstream, the basin gathered near surface treatment business. These types of production, size, grade and uneven distribution is more dispersed. The study showed that the the Wuyi water quality has dropped to worse than Class V; the the large phosphorus wastewater generated by the phosphating process enterprise is the primary source of contamination of the the Wuyi water phosphorus pollution; Wuyi average total phosphorus concentration has reached the standard of water eutrophication. And part of the urban sewage treatment system in the basin is still not fully put into use; most industrial sewage treatment facilities are not equipped or imperfect: pickling, phosphating wastewater treatment and management technology can not meet the wastewater treatment requirements in urgent need of further improvement and innovation. The above problems Jinhua River watershed and the water environment of the Qiantang River, biodiversity and socio-economic development will produce varying degrees of impact. With the rapid socio-economic development of the basin, the water pollution problem will become more serious, the compliance rate of the water environment function zones will also declining, which will seriously affect the water environment and ecology in the basin with water quality and safety of drinking water sources. For the Wuyi industrial characteristics of phosphorus pollution remediation measures should be distinguished from the general lakes, reservoirs and other agriculture, life as the primary source of phosphorus pollution of water bodies. Studies have shown that clean production and pollution minimization technique is improved phosphating process, from the source to the main direction of development to reduce phosphorus pollution; biochemical methods of sustainable wastewater treatment process for phosphorus removal and phosphorus recovery technology trends; 3S technology for water environment management; comprehensive promotion of online monitoring technology; long-term supervision mechanism and sectoral coordination mechanisms; strictly control the total discharge of pollutants; the phosphating process enterprise restructuring and regional planning; government departments a positive guide and research to encourage policies; strengthening of environmental legislation and law enforcement, and so on, is currently the most effective remediation of the Wuyi industrial phosphorus pollution measures. Therefore, the study of the impact of the Wuyi Basin industrial phosphorus pollution of the water environment and pollution remediation countermeasures to improve the Wuyi water quality, to strengthen Jinhua River watershed pollution control and ecological environment protection and rational use of water resources, optimize the industrial layout, and promote the watershed sustainable socio-economic development and building a harmonious society, to protect the water security of the people, to achieve the sustainable development of water resources has important theoretical and practical significance.
