Problems solved by technology
At present, most water purification plants in China mainly use inclined tube sedimentation tanks and lateral flow inclined plate sedimentation tanks to carry out sludge sedimentation operations, and a small number of water purification plants use advection sedimentation tanks and small spacing inclined plate sedimentation tanks. However, the application technology of advection settling tanks and small-space inclined plate settling tanks is not mature; compared with the method of inclined tube settling tanks, advection settling tanks occupy a large area and have high civil construction costs lack of
After the inclined tube sedimentation tank has been in operation for a long time, a certain amount of sludge will be deposited in the sedimentation inclined tube, resulting in a decrease in the cross-sectional area of the sedimentation inclined tube, which affects the sedimentation effect of the sedimentation inclined tube on sludge. The inclined tube in the prior art The pipe sedimentation tank uses a relatively complex and high energy consumption flushing pump to regularly flush the sedimentation inclined pipe. The above method needs to be further improved
[0003] In addition, sewage treatment also includes sludge dewatering process. In the prior art, sludge dehydration is mainly realized by the following equipment: plate and frame filter press, centrifugal dehydrator and belt filter press, etc.; the equipment purchase cost of centrifugal dehydrator and operating costs are higher than belt filter presses, but the former has a better working environment and lower civil engineering costs

The invention discloses a reverse-flow sludge settling and centrifuging system. The reverse-flow sludge settling and centrifuging system comprises a settling front part reservoir, a settling middle part inclined tube tank, a settling rear part drain tank, and a sludge centrifuging device, a sludge settling inclined tube and a settling inclined tube installation plate are arranged in the settling middle part inclined tube tank, the upper end of the sludge settling inclined tube is inclined towards the settling front part reservoir, a settling water supply valve control pipe and a backwash water supply valve control pipe are arranged between the settling middle part inclined tube tank and the settling front part reservoir, and a settling drain valve control pipe is arranged between the settling middle part inclined tube tank and the settling rear part drain tank; the sludge centrifuging device comprises a sludge centrifugal rotating chassis, a sludge centrifugal rotating side cover and a centrifugal rotating drive, the sludge centrifugal rotating side cover is in a cone structure, and the diameter of the upper end of the sludge centrifugal rotating side cover is less than the diameter of the lower end of the sludge centrifugal rotating side cover. The reverse-flow sludge settling and centrifuging system can conveniently wash the settling inclined tube, is simplified in structure and relatively low in energy consumption in work, and has the functions of both centrifugally dehydrating and filter-pressing dehydrating.
Description
technical field [0001] The invention relates to the technical field of sewage treatment equipment and devices, in particular to a countercurrent sludge sedimentation centrifugal system. Background technique [0002] Sludge sedimentation is the last link in sewage treatment, which is mainly used to separate the sludge and water in the mixed and flocculated sewage. At present, most water purification plants in China mainly use inclined tube sedimentation tanks and lateral flow inclined plate sedimentation tanks to carry out sludge sedimentation operations, and a small number of water purification plants use advection sedimentation tanks and small spacing inclined plate sedimentation tanks. However, the application technology of advection settling tanks and small-space inclined plate settling tanks is not mature; compared with the method of inclined tube settling tanks, advection settling tanks occupy a large area and have high civil construction costs lack of. After the incl...
