Cultivation sewage circulation purification method

Abstract

The invention discloses a culture sewage circulation purification method. The method comprises the following steps: firstly, filtering large particles and suspended substances such as livestock and poultry hair, excrement and the like by using a water collecting well and a grating, enabling the filtered sewage to automatically flow into an adsorption system, then flow into a disinfection tank and a neutralization tank, stay for a period of time, automatically flow into an artificial wetland, and finally, conveying into a livestock and poultry farm, the adsorption system is a sandwich type purification system formed by sponge, self-made charcoal and a self-made molecular sieve, and the disinfection tank uses a bactericide compounded by modified quaternary ammonium salt and banana peel. According to the breeding sewage circulation purification method, the purification degree of the breeding sewage is high, all indexes are far lower than the national first-level discharge standard, the purified water can be used in a breeding farm again, secondary recycling of the sewage is achieved, meanwhile, the planting industry and landscape appreciation are linked, and higher economic benefits are brought.

Description

technical field [0001] The invention relates to the technical field of aquaculture sewage treatment, in particular to a method for circulating purification of aquaculture sewage. Background technique [0002] Under the background that rural areas are generally encouraged to expand breeding production, my country's livestock and poultry breeding industry is booming, and in recent years, it has shown a trend of industrialization, scale and regionalization. In the process of livestock and poultry breeding, due to the sanitation and cleaning of the farm and livestock and poultry, or the natural excretion of livestock and poultry, a large amount of sewage will be generated. If it cannot be effectively treated, it will inevitably cause pollution and damage to the surrounding ecological environment, especially the water environment, especially if humans and animals drink such sewage by mistake, it will also have a greater adverse impact on their own body health. Scientific treatme...

AI Technical Summary

Problems solved by technology

[0004] Traditional livestock and poultry breeding sewage treatment still has the problems of low efficiency and high cost in the treatment of nitrogen and phosphorus

The contradiction between the processing cost of the existing technology and the low profit and high risk of breeding is prominent, and the operation management and the operation of the operator cause the existing facilities to fail to operate normally. It is of great significance to treat aquaculture sewage with low management cost and easy operation.
