Integrated treatment equipment for rural domestic sewage

Abstract

The invention discloses integrated treatment equipment for rural domestic sewage. The integrated treatment equipment is formed by sequentially connecting an anoxic pond, a planktonic carrier high-efficiency bioreactor, a floating type sloping plate settling tank, a special plant ecological reactor and a clear water collecting pool, wherein a submersible mixer, an online pH meter and a DO tester are arranged in the anoxic pond; the online pH meter, the DO tester, an ultrasonic level gauge, a planktonic carrier, a micro-porous aerator, a Roots blower and a mixed-liquid reflux pump are arranged in the planktonic carrier high-efficiency bioreactor; floating slopping plate fillers, a sludge bucket and a sludge pump are arranged in the floating sloping plate settling tank; aquatic plants, a plant fixing bed, a water distribution area, polymer porous filler, a water production area, an ultrafine aerator, a bidirectional water distributor and the Roots blower are arranged in the special plantecological reactor; the clear water collecting pool is provided with a backwashing water pump. The equipment is required to have the advantages of low investment and running cost, simple process, convenience in maintenance, stable operation, high impact resisting load, high practicability and the like.

Description

technical field [0001] The invention relates to the technical field of rural domestic sewage treatment, in particular to integrated treatment equipment combining environmental engineering technology and ecological engineering technology. Background technique [0002] At present, most rural sewage integration devices use the MBR process. Although this process improves the impact load of the sewage treatment system to withstand COD and SS, and improves the water quality of the effluent, the replacement of the traditional sedimentation process with the membrane process will inevitably increase the overall investment of the equipment. Moreover, the diaphragm is easy to foul during operation, which also increases the cost of various chemical agents and the replacement cost of the membrane system. At the same time, considering the large gap between urban and rural development in my country at this stage, and some rural areas are still in a poor and backward state, so from an economi...

Problems solved by technology

[0002] At present, most rural sewage integration devices use the MBR process. Although this process improves the impact load of the sewage treatment system to withstand COD and SS, and improves the water quality of the effluent, the replacement of the traditional sedimentation process with the membrane process will inevitably increase the overall investment of the equipment. Moreover, the diaphragm is easy to foul during operation, which also increases the cost of various chemical agents and the replacement cost of the membrane system. At the same time, considering the large gap between urban and rural development in my country at this stage, and some rural areas are still in a poor and backward state, so from an economic point of view, The promotion of MBR technology in the field of rural domestic sewage is limited by the investment cost, and it is difficult to popularize; in addition, in terms of the professional level of environmental protection practitioners, the current knowledge reserve of rural practitioners is generally insufficient, and there are also cases where the sewage treatment system is paralyzed due to operational errors Therefore, the MBR process is relatively complicated for rural practitioners and difficult to master in a short time. This is another important dilemma faced by the promotion of the MBR process in the field of rural domestic sewage
