Summary: | The invention discloses a sewage and sludge cooperative treatment system and method in a low-temperature environment. Comprising a preheating sand removal system for preheating and preliminarily filtering sewage, a new energy biochemical subsystem for removing nitrogen and phosphorus from the sewage, a biochemical sedimentation tank subsystem for filtering the sewage again, a sewage source heat pump subsystem with a heat exchange effect, and a sludge treatment subsystem for cooperatively treating sludge and kitchen waste, through the five steps of sewage preheating and desanding, biochemical reaction, mud-water separation, sewage heat exchange and cooperative treatment of sludge and kitchen waste, the problems that the effluent quality of a sewage plant is difficult to reach the standard under the low-temperature condition, the treatment cost is high in sludge remote treatment, and infrastructure is repeatedly constructed are solved.
