Efficient denitrification and dephosphorization integral sewage treatment device

Abstract

The invention discloses an efficient denitrification and dephosphorization integral sewage treatment device, which has the advantages that the treatment effect is good; the water discharging is stable; the operation cost is low. The main body structure of the device comprises a box body, wherein the box body is made of a fiber glass reinforced plastic composite material; the inside of the box body is sequentially separated into a regulating chamber, an anaerobic chamber, an anoxic chamber, an aerobic chamber, a precipitation chamber, a mixing and precipitation chamber and a sterilization chamber through separation plates; all chambers are connected through pipelines; a water inlet and a water outlet are respectively formed in the two sides of the box body, i.e., the regulating chamber and the sterilization chamber; a flow guide plate is arranged in the regulating chamber; flow passing openings are formed in the upper ends of the separation plates between the regulating chamber and the anaerobic chamber and between the anoxic chamber and the aerobic chamber; flow passing openings are formed in the lower ends of the separation plates between the anaerobic chamber and the anoxic chamber and between the aerobic chamber and the precipitation chamber; biological suspension filling materials are charged in the aerobic chamber; a gas extraction back flow system is arranged in the precipitation chamber; inclined plate precipitation is used; the mixing and precipitation chamber uses the inclined plate precipitation; a pipeline mixer is arranged on a coagulation pipe; the water dwell time in the sterilization chamber is 10 to 30min.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to an integrated sewage treatment device for efficient nitrogen and phosphorus removal. Background technique [0002] With the continuous improvement of people's living standards, the discharge of domestic sewage is also increasing, and the pollution caused is becoming more and more serious. At present, the integrated equipment based on traditional biochemical technology has the advantages of compact structure and small footprint, but the common integrated domestic sewage equipment has poor treatment effect, and the nitrogen and phosphorus content still cannot meet the effluent requirements and the effluent water quality is unstable. Discharge of treated water directly into water bodies will still lead to water pollution. [0003] There have been some studies on mobile sewage treatment equipment in the prior art. For example, the Chinese patent No. 201511035802.7 discloses a double-wall...

Problems solved by technology

At present, the integrated equipment based on traditional biochemical technology has the advantages of compact structure and small footprint, but the common integrated domestic sewage equipment has poor treatment effect, and the nitrogen and phosphorus content still cannot meet the effluent requirements and the effluent water quality is unstable. Direct discharge of treated water into water bodies will still lead to water pollution

[0003] There have been some studies on mobile sewage treatment equipment in the prior art. For example, the Chinese patent No. 201511035802.7 discloses a double-wall micro-power sewage treatment integrated equipment. The main process of the equipment is A 2 / O, but with the increasingly stringent water discharge standards, it cannot guarantee that the effluent can meet the standards stably

In addition, the Chinese patent No. 201620093041.4 discloses an integrated domestic sewage treatment equipment. The main process uses membrane equipment, and the investment cost is relatively high.
