Embodiment 1

[0026] A slaughterhouse wastewater treatment system, comprising an oil separation sedimentation tank, a first aerobic tank, an SBR reactor, a facultative oxygen tank, a second aerobic tank, a regulating tank, a fluidized bed reactor, and a flocculation sedimentation tank connected in sequence, There are two mutually symmetrical sludge discharge pipes on the lower side of the oil separation sedimentation tank, which are connected to the sludge pool below the sludge discharge pipes, and a middle grid is installed at the outlet of the fluidized bed reactor. Coarse grids are installed at the outlet of the flocculation sedimentation tank, and screens are connected to both the middle grid and the coarse grid. The distance between the bars of the coarse grid is 50mm, and the distance between the bars of the medium grid is 30mm. The SBR reactor contains activated sludge, and a mixture of sawdust, diatom mud and peat soil is added to the activated sludge for domestication treatment, an...

Abstract

The invention discloses a treatment system for slaughter house wastewater, belonging to the technical field of slaughter house wastewater treatment. The treatment system for slaughter house wastewatercomprises an oil separation sedimentation tank, a first aerobic tank, an SBR reactor, a facultative tank, a second aerobic tank, an adjusting tank, a fluidized bed reactor and a flocculation sedimentation tank. According to the invention, disinfection and sterilization treatment is not needed, and a wastewater treatment agent contains disinfection and sterilization components, so wastewater treatment cost can be reduced, and wastewater treatment efficiency is improved. According to the method, the wastewater treatment agent and a saw dust mixture are combined for treatment to achieve maximumreduction degree of COD, BOD and ammonia nitrogen, wherein the degradation rate of COD is 98.62%-99.86%, the degradation rate of BOD is 99.39%-99.48%, and the degradation rate of ammonia nitrogen is 94.74%-96.05%; so remarkable economic benefits are obtained.

Description

technical field [0001] The invention belongs to the technical field of slaughterhouse wastewater treatment, and in particular relates to a slaughterhouse wastewater treatment system. Background technique [0002] Since the reform and opening up, my country's economy has developed rapidly, and more social resources have been developed. This is the case with the development of the slaughtering and meat processing industry, which not only meets people's demand for meat products, but also surpasses today's Many developed countries in the world have become important meat exporting countries. Taking the slaughtered sheep as an example, the main processes are ①sending, ②showering, ③stunning, ④slaughtering and bloodletting, ⑤removing head and hooves, ⑥peeling, ⑦opening, ⑧carcass arrangement, ⑨inspection, stamping, weighing, leaving the factory, etc. Nine steps are processed. At present, most places in our country have realized centralized slaughtering of livestock. At the same time...
