In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a domestic sewage advanced treatment system which characterized in that: including consecutive settling pond, ozone oxidation pond, remove nitrate resin exchanger, dephosphorization resin exchanger, the outlet conduit of settling pond links to each other with ozone oxidation pond inlet channel, set up ozone gas distribution pipe in the ozone oxidation pond, the outlet pipe of ozone oxidation pond passes through the tubing pump and links to each other with the inlet tube that removes nitrate resin exchanger, the outlet conduit who removes nitrate resin exchanger passes through the tubing pump and links to each other with the inlet tube that removes dephosphorization resin exchanger, the play water discharge to reach standard of dephosphorization resin exchanger's outlet pipe discharges.
In the scheme, the method comprises the following steps: and sludge at the bottom of the clarification tank enters a sludge concentration tank. And carrying out outward transport of the concentrated sludge.
In the scheme, the method comprises the following steps: the ozone gas distribution pipe is connected with an ozone generator.
In the scheme, the method comprises the following steps: the nitrate removal resin exchanger and the phosphorus removal resin exchanger are both provided with resin regeneration reactors.
In the scheme, the method comprises the following steps: the nitrate removing resin exchanger and the phosphorus removing resin exchanger are two, one is opened and the other is prepared. The processing efficiency is improved.
Has the advantages that: the domestic sewage treatment system provided by the invention adopts the clarification tank to replace a three-sedimentation tank, so that suspended matters and COD (chemical oxygen demand) in the effluent of the two-sedimentation tank are further removed, and the treatment efficiency of a subsequent ozone reaction tank is favorably improved. The ozone reaction tank is adopted to simultaneously remove COD and ammonia nitrogen, the reaction time is short, and the investment cost is low. Nitrate is removed by adopting the nitrate-removing resin exchanger, so that the removal efficiency is high and the removal effect is stable. The total phosphorus is removed by adopting the phosphorus removal resin exchanger, the removal efficiency is high, the concentration of the total phosphorus in the effluent is less than 0.1mg/L, the removal effect is good, and the emission requirements of the environmental quality standard of surface water (GB 3838-
