The invention provides integrated
sewage treatment recycling equipment with a pretreatment tank and relates to the technical field of treatment of
livestock and poultry breeding
wastewater. The equipment structurally comprises a tank body, wherein the interior of the tank body is separately provided with a
sewage treatment tank and an equipment room, and a deep
treatment system is arranged in theequipment room. A liquid inlet
pipe enters the tank body and communicates with the
sewage treatment tank, the
sewage treatment tank is connected with the deep
treatment system through a pipeline, thedeep
treatment system communicates with a liquid outlet
pipe, the
sewage treatment tank comprises the pretreatment tank, a first stage anoxic tank, a first stage aerobic
pool, a second stage anoxic tank and a second stage aerobic
pool, the first stage anoxic tank, the first stage aerobic
pool, the second stage anoxic tank and the second stage aerobic pool communicate with one another sequentially,and the bottom of the pretreatment tank is of a mud bucket structure. According to the integrated
sewage treatment recycling equipment with the pretreatment tank, anaerobic digested
effluent of a breeding farm is treated through a two-stage A / O, MBBR and MBR combined process, so that
effluent of the equipment reaches recycled-water
water quality standards, and zero
discharge of
wastewater is achieved; through additionally arranging the pretreatment tank and corresponding refluxing devices and collecting devices, the equipment has relatively good
treatment effect on influent digested effluentof different water qualities and is high in applicability, and thus, popularization and application are facilitated.
