Rural domestic sewage multi-stage low-power ecological treatment and resource utilization terminal

Abstract

The invention discloses a rural domestic sewage multi-stage low-power ecological treatment and resource utilization terminal which comprises an artificial wetland system, wherein one end of the artificial wetland system is connected with a water inlet pipe, the other end of the artificial wetland system is connected with a water outlet main pipe. The rural domestic sewage multi-stage low-power ecological treatment and resource utilization terminal further comprises a grating well, a septic tank, a sedimentation tank and a biological tank which are sequentially arranged, wherein a basket grating is arranged in grating well, and one end of grating well is connected with a water inlet header pipe; a water inlet of the septic tank is connected with a water outlet of the grating well; a water inlet of the sedimentation tank is connected with the septic tank; the biological tank comprises an anaerobic tank, an aerobic tank and a clarification tank which are communicated in sequence, a plurality of three-dimensional elastic filler pieces are hung in the anaerobic tank, and an aerator is arranged in the aerobic tank; and the water inlet pipe is connected with a clarification tank. The terminal has the effects that sewage entering a constructed wetland system has low impurity content, low organic matter content, low suspended matter content, low particulate matter content, good effluent quality and high effluent stability.

Description

technical field [0001] This application relates to the field of domestic sewage treatment, in particular to a terminal for multi-stage low-power ecological disposal and resource utilization of rural domestic sewage. Background technique [0002] As the public's awareness of environmental protection continues to strengthen, the necessity of rural environmental improvement is becoming more and more prominent. However, in the implementation of rural sewage treatment, the most difficult defect is that rural residents are often scattered, so the use of centralized sewage Treatment devices are likely to increase the cost of sewage treatment. At present, the integrated sewage treatment equipment, purification tanks and other rural domestic sewage treatment facilities on the market often require the support of infrastructure such as electricity due to their high integration. The cost of medicines is still relatively high. For rural areas with weak economic strength, these technolog...
