The waste water discharged from the slaughterhouse contains a large amount of oil and fat, the pathogenic microorganisms are brown-red, and the smell is strong. Infectious feces must be individually disinfected to make them harmless. If the treatment does not meet the standards, it will affect the environment and even the environment, and it must be treated before discharge. In order to meet the discharge standards after slaughtering sewage treatment, the drainage devices of rural sewage treatment equipment should meet the requirements.
Rural sewage treatment equipment is a kind of sewage that can be adjusted according to water level changes. The drain pipe is submerged to a reasonable depth below the surface to prevent scum from entering. The ideal drainage device for rural sewage treatment equipment should meet the following conditions:
1. Rural sewage treatment equipment has a large amount of water per unit time, the flow rate is small, and the sediment sludge will not appear again;
2, the water collection port decreases with the water level, and the static precipitation state in the reaction process is always maintained during the drainage process;
3, the rural sewage treatment equipment drainage equipment is sturdy and durable, the displacement can be adjusted steplessly, and the degree of automation is high.
When setting the circulating drainage time of rural sewage treatment equipment, pay attention to the overflow load of the supernatant liquid discharge device, that is, determine the quantity of equipment required. The water depth at the interface of activated sludge is small, mainly to prevent sludge from floating. It is determined by the supernatant discharge and overflow load. In terms of performance, the water depth should be as small as possible. As the overflow load of the supernatant liquid discharge device increases, the amount of treated water discharged per unit time increases, the drainage time can be shortened, and the capacity of the corresponding subsequent processing structure of the rural sewage treatment equipment must be enlarged. When the drainage is about to end, the activated sludge deposited during the drainage floats, and the rural sewage treatment equipment is discharged from the middle of the sedimentation process according to the operating principle of the SBR method.
When the rural sewage treatment equipment is put into operation, the operator must be responsible and operate carefully, pay attention to details, equipment problems or the water quality does not meet the standards, and the equipment must stop emergency treatment immediately. Various instruments and probes should be calibrated and cleaned frequently. The concentration of the drug to be prepared should be fully prepared according to the process requirements. Do not increase your concentration to save trouble.
