Not She You inlet and outlet, be respectively equipped with baffle on the inner wall at left and right sides of rectangle water storage boxAnd baffle, the gear
PlateAnd baffleFlow direction in rectangle water storage box is become into " oneself " font, " u "-shaped is equipped in rectangle water storage box upper surface
Blowpipe is laid with the air branch pipe being connect with rectangle water storage box cavity, in sky on blowpipe
The lower end of gas branch pipe is equipped with diffuser.
Above-mentioned diffuser is distributed on baffleFront and rear sides and baffleFront side.
The prior art compares, the good plating acidic and alkaline waste water processing unit device of the utility model clean-up effect, in elevator pump
The biologic packing material integrated reaction device of removal remnants COD, ammonia nitrogen and total phosphorus, biologic packing material are equipped between flocculation sedimentation tank
Integrated reaction device includes rectangle water storage box, and inlet and outlet are respectively equipped in rectangle water storage box Upper diagonal line position,
It is respectively equipped with baffle on the inner wall at left and right sides of rectangle water storage boxAnd baffle, the baffleAnd baffleRectangle is stored
Flow direction in water tank becomes " oneself " font, is equipped with the blowpipe of " u "-shaped in rectangle water storage box upper surface, is pressing
It is laid with the air branch pipe being connect with rectangle water storage box cavity on contracting air delivery pipe, diffusion is equipped in the lower end of air branch pipe
Pipe can be effectively removed in this way because there is the content for being chemically treated incomplete COD ammonia nitrogens total phosphorus in leading portion soda acid water so that its
Draining reaches requirement environmental protection standard or more；Specifically, baffleAnd baffleIt is conducive to extend water of the flow in rectangle water storage box
Total distance is flowed, uniformly distributed diffuser is conducive to efficiently be removed remaining COD, ammonia nitrogen to the water body for flowing through rectangle water storage box
And total phosphorus.

Its principle：Biologic packing material integrated reactor is the effect by anaerobe under condition of free-dioxygen, will be given up
For various complicated organic matter decomposition and inversions in water at the process of the substances such as methane and carbon dioxide, anaerobic bio-treated is one multiple
Miscellaneous chemistry of micro-organisms process hydrolyzes acidogenic bactria, hydrogen-producing acetogenic bacteria and production first by the bacterium of three big main groups
The synergy of alkane bacterium is completed.Anaerobic digestion process is roughly thus divided into three continuous stages, the first stage is water
Solve souring stage.The macromolecular of complexity, insoluble organic matter is first hydrolyzed to small molecule under the action of exoenzyme, dissolubility has
Then machine object penetrates into cell body, decompose and generate volatile organic acids, alcohols, aldehydes etc..This stage mainly generates more advanced
Aliphatic acid.Itrogenous organic substance decomposes the NH3 generated other than providing the nitrogen source of synthetic cell substance, partial ionization in water, shape
At NH4HCO3, have the function of buffering digestive juice pH value.Second stage is the hydrogenesis and acetogenesis stage.In hydrogen-producing acetogenic bacteria
Under the action of, the various organic acids of first stage generation, which are decomposed, is converted to acetic acid and H2, when degrading odd number carbon organic acid
Also form CO2.Phase III is the methane phase stage.Acetic acid, acetate, CO2 and H2 etc. are converted to methane by methane-producing bacteria
。
Although anaerobic digestion process can be divided into the three above stage, in anaerobic reactor, three phases are simultaneously
It carries out, into test of many times is crossed, not installing COD contents during biologic packing material integrated reaction device 8 is discharged in conventional treatment process is
Within the scope of 120-150mg/L, total phosphorus is 1.1-1.5mg/L or so, 25-35mg/L of ammonia nitrogen or so, and passes through biologic packing material
COD can be reduced to 70-28mg/L or so after integrated reaction device 8, total phosphorus is also in 0.6-0.9mg/L hereinafter, ammonia nitrogen
It can effectively controlling in the acceptability limit of 10-15mg/L, capable of effectively removing endless because there is chemical treatment in leading portion soda acid water
Full COD ammonia nitrogen total phosphorus indexs.
