Description
Technical Field
The utility model belongs to urban water system external source pollution control field especially relates to a suspension formula microorganism purification band structure for agricultural water purifies.
Background
The urban water environment pollutants are exogenous pollutants from upstream areas and endogenous pollutants of cities. Firstly, water and soil loss exists in most rural areas at the upstream of rivers, and the pollution of chemical fertilizers and pesticides becomes a main water body pollution source. The economic level of countries such as Europe is high, people are few and many, and more modes of dredging the river channel, directly aerating and further recovering the river channel wetland are adopted, so that the mode has large investment, good effect and quick response; although japan is economically developed, the greatest limiting factor is the abundance of people, so that the purification technology for river water quality in japan mainly adopts indirect purification, and discharges upstream water into a downstream urban river after purifying the upstream water, and frequently uses underground means to save land.
In China, according to the estimation of experts, about 1/3 (Zhumegalian, 2005) of nitrogen and phosphorus pollutants from industrial and domestic sewage and agricultural pollution in water bodies of China currently exists, nearly 50% of underground water is polluted by agriculture, and more than 50% of nitrogen and phosphorus in surface water such as lakes and the like are polluted by agriculture. The research results of the soil fertilizer institute of the Chinese academy of agricultural sciences show that: in the watershed with serious water pollution in China, the living pollution discharge of farmlands, rural livestock and poultry breeding and urban and rural junctions is the main reason for eutrophication of water nitrogen and phosphorus (Zhang Wei, 2004).
In recent years, China also takes a series of measures against the influence of agricultural pollution on urban water systems. For example, professor of the national philosophy of the ministry of water conservation proposes the concept of "ecological water engineering". Meanwhile, a large number of river ecological management projects are developed in China, such as Shanghai Suzhou river management project, Nanjing Qinhuai river management project, Chengdufu south river management project, great national projects of '863', namely Taihu lake water pollution control and water body remediation technology and engineering demonstration project and the like. The river treatment in China mainly adopts a physical mode and a chemical mode, and the application of a biological ecological mode is in a starting stage. The existing purification system adopting a biological ecological mode to realize water purification usually adopts a single scheme, and if the existing purification system simply utilizes artificial aquatic plants or other facilities for fixing microorganisms as a purification device, the purification effect is poor. For example, the artificial purification belt disclosed in the Chinese patent (CN204752322U) comprises floating balls, elastic fillers, ceramsite biochemical balls and pendants; one end of the elastic filler is fixed on the pendant, the other end is fixed on the foam floating ball, and the middle is connected with the ceramsite biochemical ball in series.
