Inclined plate tube-electroflotation and filtration integrated device and sewage treatment method

Abstract

The invention discloses an inclined plate pipe-electroflotation and filtration integrated device and a sewage treatment method. The inclined plate pipe-electroflotation and filtration integrated device comprises a pool body and a water inlet pipe, the water inlet pipe is installed at one end of the pool body, a sludge discharge pipe is fixed in the lower end of the pool body, and one end of the sludge discharge pipe penetrates through the pool body and is arranged on the outer side of the pool body; an aeration branch pipe is fixed inside the lower end of the pool body, an aeration main pipe is arranged at one end of the pool body, one end of the aeration branch pipe penetrates through the pool body and is fixedly connected with one end of the aeration main pipe, an air blower is fixed at the other end of the aeration main pipe, and the air blower is fixed at the upper end of the tank body. The shortages of the prior art are overcome, the problems of long sedimentation time and poor sedimentation effect of an existing free sedimentation pool are solved, a simple unit combination is adopted, an inclined plate sedimentation pool, an electroflotation pool and a sand filter pool are arranged, particles in sewage flow through multi-stage treatment units, the sedimentation effect is improved, finally, the sewage is filtered from by sand filter pool, and the sedimentation efficiency and effect are improved.

Description

technical field [0001] The invention belongs to the related technical field of sewage treatment devices, and in particular relates to an integrated device of inclined plate tube, electric floatation and filtration and a sewage treatment method. Background technique [0002] Inclined plate (tube) sedimentation tank is a high-efficiency combined sedimentation tank designed according to the shallow pool sedimentation theory, also collectively referred to as shallow pool sedimentation tank. Set up many dense sloping plates (or sloping tubes) in the sedimentation area, so that suspended impurities in the water can settle in the sloping plates or sloping tubes. The sloping plate (pipe) slides down to the bottom of the tank, and the treated and settled sludge move and separate in each shallow sedimentation layer, and finally discharged in a concentrated manner, while the rising sewage is separated from the sludge, and the water quality is purified. [0003] Electric flotation is a...
