Description

Technical Field

[0001] The utility model relates to the field of sludge treatment, in particular to a secondary sedimentation tank sludge treatment device. Background Art

[0002] According to the source of sewage, sewage can be defined as liquid or water carrying wastes mixed with groundwater, surface water, snowstorms, etc. discharged from residential, institutional, commercial or industrial areas. Sewage has many categories, and there are also many technologies and processes to reduce the impact of sewage on the environment. According to the source of sewage, sewage can be divided into these four categories. Category 1: Industrial wastewater comes from sewage from manufacturing, mining and industrial production activities, including runoff or leachate from industrial or commercial storage and processing, and other wastewater that is not domestic sewage. Category 2: Domestic sewage comes from sewage from residential, office, institutional or similar; sanitary sewage; sewer sewage, including industrial wastewater mixed with domestic sewage in the sewer system. Category 3: Commercial sewage comes from commercial facilities and some components exceed domestic sewage. Non-toxic and harmless sewage. Such as catering sewage. Laundry sewage, animal breeding sewage, sewage generated by hair salons, etc. Category 4: Surface runoff comes from rainwater, snow water, highway drainage, water from cities and industrial areas, etc. Surface runoff does not penetrate into the soil and enters groundwater along the streets and land.

[0003] Sewage treatment is currently the biggest problem in residential, agricultural and industrial areas. Sewage can meet emission standards after being treated in multiple sedimentation tanks. However, current sewage treatment requires multiple treatment tanks, including aerobic and anaerobic tanks, etc., so it occupies a large area and requires a large area to be divided for treatment.

[0006] A water outlet cavity 4 is vertically arranged in the middle of the primary sedimentation tank, the bottom of the water outlet cavity 4 passes through the primary sedimentation tank and is provided with a primary water outlet 5, and a plurality of primary sedimentation tank water outlet holes 6 are arranged in a circular array on the upper side of the water outlet cavity 4.

[0007] The circular secondary sedimentation tank group is arranged below the primary sedimentation tank 1 and is sealed and connected to the outer wall; a conical guide cover 7 is arranged above the clean water tank, the upper part of the conical guide cover 7 faces the water outlet of the water outlet cavity, and the lower end of the conical guide cover corresponds to the secondary sedimentation tank.

[0008] The secondary sedimentation tanks 2 are provided with 12 in number.

[0009] An outlet pipe 8 is arranged on the side wall separating the upper end of the secondary sedimentation tank 2 from the clean water tank, and an oblique opening is arranged below the outlet pipe on one side of the secondary sedimentation tank.

[0010] A motor 9 is provided at the upper end of the water outlet chamber, and the motor drives a stirring paddle 10 in the primary sedimentation tank to stir.

[0011] The beneficial effects of the utility model are:

[0012] The primary, secondary and clear water tanks of the device are integrated in one tank body, the aerobic primary tank is arranged at the top, and the secondary anaerobic tank is arranged at the bottom, which is reasonably arranged; the sewage flow distance is increased through various drainage ports and water outlet chambers, and the treatment time is increased.
