Abstract

The invention discloses a physicochemical sewage processing system and method for simultaneously removing COD and total phosphorus. The sewage processing system comprises an improved reaction tank, animproved horizontal flow sedimentation tank, a magnetic powder recovering system, and a sludge discharge system. The improved reaction tank is divided into a coagulation reaction region, a magnetic powder loading region, and a flocculation reaction region. Between the improved reaction tank and the improved horizontal flow sedimentation tank, a water distribution adjusting region is arranged. A flow adjusting device and a triangular guide plate are arranged in the water distribution adjusting region. A horizontal pipe is arranged in the upper layer of the improved horizontal flow sedimentation tank, and a mud scraper is arranged on the bottom of the improved horizontal flow sedimentation tank. The magnetic powder recovering system comprises a separation groove, a cutting machine, and a magnetic separator, which are arranged in sequence. The sludge discharged from the bottom of the improved horizontal flow sedimentation tank is introduced into the separation groove through a pipeline;the separation groove is provided with two sludge discharge pipelines; one of the sludge discharge pipelines is connected to the magnetic powder loading region of the improved reaction tank, the otherone is connected to the cutting machine; and the magnetic powder separated by the magnetic separator is added into the magnetic powder loading region again. The provided system and method can efficiently remove COD, TP, and SS.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a physical and chemical sewage treatment system and method for synchronously removing COD and total phosphorus. Background technique [0002] The process of magnetic flocculation sedimentation technology is to add magnetic powder and flocculant during the flocculation sedimentation process, so that the magnetic powder and solid suspended matter are combined into magnetic flocs, and the flocs are easier to settle at a high speed. Although the addition of magnetic powder can improve the flocculation effect, the effect is still unsatisfactory, especially for sewage with high COD and influent total phosphorus, and the effluent COD and total phosphorus are still high. If the magnetic powder and flocculant are simply added, the cost of sewage treatment will undoubtedly be increased, and the amount of sludge will also increase. Moreover, the sludge containing magnetic powder i...
