Sewage and sludge processing system

Abstract

The invention discloses a sewage and sludge processing system. A cloth filter is connected with an ultraviolet disinfection tank; a coarse screen, an influent pump station, an aerated grit chamber, a fine screen, a photochemical pool, an anaerobic tank, a anoxic tank, an MBBR biological reaction tank, a secondary sedimentation tank, a two-stage pumping station, a coagulative sedimentation tank, the cloth filter, a disinfection oxidation pond and a clear-water reservoir are connected successively; the clear-water reservoir is connected with a suction well and an efflux pump station successively; the photochemical pool is connected with the MBBR biological reaction tank; the secondary sedimentation tank is connected with the photochemical pool and then connected with pipelines behind the photochemical pool; the MBBR biological reaction tank is connected with the disinfection oxidation pond; the coagulative sedimentation tank is connected with a sludge concentration tank, a sludge homogeneous tank, a sludge dewatering machine and a sludge filter press in order; the secondary sedimentation tank is connected with a pre-concentration tank; the pre-concentration tank is connected with a sludge concentration machine, a digestion tank and a post-concentration tank in order; and at the same time, the pre-concentration tank and the post-concentration tank are connected with a sludge conditioning tank. With the sewage and sludge processing system, the sewage processing quality is improved; and regression of an ecological system is achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage sludge treatment system. Background technique [0002] At present, most of the wastewater treatment at home and abroad adopts biological treatment-based technology, especially for pharmaceutical and chemical wastewater with complex components, high organic content, high toxicity, deep color and high salt content. The reason is that biological treatment The process has the advantages of low operating cost and high treatment degree, but at the same time, there are many major problems that need to be solved urgently in the biological method, such as large amount of sludge discharge, serious foul odor phenomenon in the sewage site and surrounding areas, and rotten sludge. Waiting too much, seriously polluting the environment and affecting the ecology. [0003] The general principle of the planning, design and construction of the comprehensive utilization system of ...
