Simulated ecological environmentally friendly harmless biological treatment process

Abstract

The invention provides a simulated ecological environmentally friendly harmless biological treatment process, and belongs to the technical field of sewage treatment. The simulated ecological environmentally friendly harmless biological treatment process is characterized by comprising the following steps: (1) sewage collection: pumping the sewage into a settling pond; (2) preliminary settling: discharging settled scum, and draining the sewage into a pre-reacting device after the scum is discharged; (3) pre-reaction: decomposing the sewage by a complex microbial community, and separating out organic scum and inorganic precipitate through a solid-liquid separating device; (4) ecological reaction: continuously switching over an anaerobic condition and an aerobiotic condition of biological stuffing to further decompose organic pollutants; and (5) discharging: directly discharging or recycling. The simulated ecological environmentally friendly harmless biological treatment process is used with efficient microorganisms, various kinds of organic wastewater in the livestock and poultry industry, the slaughter industry, animal innocent treatment industrial, urban black stinking water and the like with high pollutant concentration are treated, any chemical preparations are not added in a whole treatment process, the water does not have obvious odor, and the green ecological treatment effect without secondary pollution is achieved completely.

Description

technical field [0001] The imitation eco-environmental protection and harmless biological treatment process belongs to the technical field of sewage treatment. Background technique [0002] With the rapid development of the livestock and poultry breeding industry (including the related deep processing industry), there is no effective harmless treatment of a large amount of manure produced by livestock and poultry farms, and a large amount of livestock and poultry manure is discharged and accumulated randomly without treatment. Directly used for agricultural fertilization, resulting in too high nitrite and phosphorus nitrate content in the soil environment, reducing the value of the soil; if it is directly discharged into the water, the nitrate content in the water body will increase. If it seeps into the ground through the surface, it will be serious. Threats to human health; harmful gases spread into the air, reducing air quality, causing serious pollution to the environmen...

AI Technical Summary

Problems solved by technology

[0007] However, due to the improper or untimely treatment of livestock and poultry manure in the existing livestock and poultry manure treatment system, the utilization rate is low, and the full utilization of resources cannot be realized, resulting in a new pollution source; it cannot be recycled, and it cannot be harmless. In addition, there are a series of problems such as poor economic feasibility
