Embodiment Construction

[0026] The following is a further detailed description of the high-concentration farm organic sewage treatment method of the present invention through specific examples.

[0027] This embodiment provides a method for treating organic sewage in high-concentration farms. The schematic diagram of the process flow of the treatment method is as follows: figure 1 shown, including the following steps:

[0028] 1. The waste water from washing the pig room every day is sent to the sewage collection tank through the sewage pipe. The sewage collection tank is equipped with a mechanical grille to remove the solid matter in the waste water through the mechanical grille, thereby reducing the processing load of the subsequent process;

[0029] 2. The waste water from which solid matter has been removed is sent to the three-stage sand settling and slag separation tank to remove the fine particles in the waste water, and then uniformly enters the regulating tank;

[0030] 3. The black film fe...

Abstract

The invention relates to an organic sewage treatment method for a high-concentration culture farm. The organic sewage treatment method comprises the following steps of sending the wastewater of the culture farm into a centralized wastewater tank via a blowdown pipe to remove solid matters in the wastewater; then, sending into a three-level sand settling and slag isolation tank to remove fine particles in the wastewater, enabling the wastewater after separation of fine particles into a conditioning tank via high level difference, fermenting by a black membrane overtime anaerobic fermentation bag, enabling the wastewater to flow into the conditioning tank again via high level difference, enabling a lifting pump to send the wastewater into a biological A / O (anoxic and anaerobic) multiplying oxidizing tower to physically and chemically treat and denitrify, enabling the wastewater to flow into a secondary settling tank, and separating clean water and sludge of the wastewater in a solid and liquid separating way in the secondary settling tank; enabling activated sludge to flow back into the conditioning tank, and enabling the clean water to flow into a multifunctional oxidizing pond; enabling the multifunctional oxidizing pond to decompose, consume and absorb organic matters in clean water via aquatic creatures, and enabling the clean water to flow into a biological filter tank; and enabling the biological filter tank to isolate the suspensions. The organic sewage treatment method has the beneficial effects that the structure is simple, the processing is convenient, the efficiency is high, the energy-saving effect is realized, and the safety and reliability are realized.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a treatment method for high-concentration farm organic sewage. Background technique [0002] Sewage from farms mainly includes animal urine, some animal manure, and flushing water from breeding houses. It is a high-concentration organic sewage with a high content of suspended solids and ammonia nitrogen. After this untreated sewage enters the natural water body, it will increase the content of suspended solids, organic matter and microorganisms in the water, change the physical, chemical and biological community composition of the water body, and deteriorate the water quality. Sewage also contains a large number of pathogenic microorganisms that will spread through water bodies or through aquatic animals and plants, endangering the health of humans and animals. In order to achieve the organic combination of economic benefits, social benefits and environmental benefits, ...
