Integrated urban and rural sewage treatment equipment for environmental protection

With the development of animal husbandry in China, industrial competition has become increasingly fierce, and the scale and intensive development of animal husbandry has become an inevitable trend. Large scale breeding has high feeding technology, unified management, reduced costs, and improved economic benefits. However, the environmental pollution caused by the discharge of a large amount of concentrated feces flushing sewage is also becoming more and more serious. Then conduct machine experiments to determine the more suitable quantity and model, so as to ensure that no matter which process, dehydration equipment, or dehydration method is used. Both can achieve good sludge dewatering effect. Some small-scale sewage treatment plants or plants with low sewage concentration. First, conduct a beaker test to determine the initial amount of addition. PAC will also be selected as the sludge dewatering equipment, which will be combined with a plate and frame filter press. Because the effectiveness of sludge dewatering is closely related to factors such as sludge concentration, sludge properties, dewatering equipment, etc.

The manure, urine, excrement, and wastewater from the aquaculture industry contain a large amount of organic matter, nitrogen, phosphorus, suspended solids, and pathogenic bacteria, which produce a foul odor. Direct discharge into rivers or surface water will seriously pollute water sources and soil environments, destroy the original functions of water bodies, endanger human health and agricultural and fishery production, such as eutrophication, and cause fatal damage to water quality The reasons for this are nothing but the drive of interests, the influence of local protectionism, and the low cost of pollution discharge. Some polluting enterprises are also major taxpayers in the local area, serving as the local god of wealth. It is inevitable that they will receive special attention in order to achieve their so-called political achievements during their tenure. Toxic substances such as chlorides and chromium were mercilessly discharged into the Yangtze River.
