Problems solved by technology

[0004] The purpose of the present invention is to solve the poor effect of ammonia nitrogen removal when the anaerobic process in the existing biological treatment of high organic matter and high ammonia nitrogen wastewater treats this kind of wastewater, and the aerobic process alone treats this kind of wastewater. Aerobic combined to deal with the problems of large area, long process route and high infrastructure cost of this kind of wastewater, and then provide a biological treatment equipment for wastewater with high organic matter and high ammonia nitrogen

Abstract

The invention discloses biological treatment equipment for high-organism and high-ammonia nitrogen wastewater, and relates to biological treatment equipment for wastewater. The invention solves the problems that in the prior high-organism and high-ammonia nitrogen wastewater biological treatment, an anaerobic process for treating the wastewater is adopted and has poor ammonia nitrogen removing effect; an aerobic process for independently treating the wastewater is adopted and has high investment and operating expense; and an anaerobic-aerobic combined process for treating the wastewater is adopted and needs large occupied area, long process route and high capital construction expense. Anaerobic particle sludge is arranged inside an upper cylinder body; a triphase separator are arranged inside an upper anaerobic reaction cylinder body; an aerobic reaction cylinder body is sleeved on an anaerobic treatment device; an aerobic reaction body is arranged inside the aerobic reaction cylinderbody; a mixing and stirring device is arranged inside a cavity body; the upper end of a water inlet pipe is fixedly connected with the upper end face of a first effluent weir; and the lower end of the water inlet pipe is arranged inside the aerobic reaction body. The biological treatment equipment has the advantages of good ammonia nitrogen removing effect, small occupied area, low capital construction expense, simple structure, and the like.

Description

technical field [0001] The invention relates to wastewater biological treatment equipment, which belongs to the technical field of wastewater treatment equipment. Background technique [0002] With the continuous improvement of the level of industrialization and people's living standards, human beings have produced a large amount of wastewater containing high concentrations of organic matter and high concentrations of ammonia nitrogen in production and life. This kind of high-concentration organic wastewater is directly discharged or washed into the water body with rainwater, which will consume a large amount of dissolved oxygen in the water body, making the water body black and smelly. A large amount of nitrogen in water is one of the important reasons for the eutrophication of water bodies. Once eutrophication occurs in the water body, the aquatic organisms in the water body will gradually die, and in severe cases, the water body will lose its use function. [0003] Alth...
