Abstract
The present invention proposes one kind of double side diverting and hydraulically circularly clarifying method for treating waste water. It has the technological process as shown and has double side diverting pond and hydraulically circularly clarifying pond to replace the distributing well, biological pond and secondary settling tank in the sewage treating AO2/O method. Compared with available sewage treating AO2/O method, the present invention has the advantages one low investment, high sewage treating effect, low power consumption, low cost, etc.
Description
Technical field
What the present invention relates to is sewage water treatment method, particularly double-face flow-guiding circular clarifying formula sewage water treatment method.
Background technology
Produce large amount of sewage in Human's production and the life process, it has not only polluted our living environment, has also reduced tellurian used water resource.Improving our living environment, sewage is handled, is problem anxious to be solved.Sewage disposal has several different methods, wherein usefulness wider be active sludge A-A-O method (being the english abbreviation of Anaerobic-Anoxic-oxic) it be anaerobic-anoxic-aerobic biological denitrification phosphate-eliminating process, its technical process is:
This technical process is simple, be beneficial to engineering construction, has the denitrogenation dephosphorizing function simultaneously.There is certain shortcoming in this technology, and floor space is big, energy consumption is high, working cost is high.
Summary of the invention
The objective of the invention is to propose a kind of effective, energy consumption is low, working cost is low double side diverting and hydraulically circular clarifying waste water treating method.
The present invention realizes like this.Its flow process is:
Wherein, with double-face flow-guiding pond and circulatior clarifier replaceable operation chain the distributing well of A-A-O method, biological tank, second pond operation.The double-face flow-guiding pond is adopted patented technology to constitute (patent No. 98121863.6) circulatior clarifier and is selected for use by national standard.
Its principle of work is as follows:
Sewage in the equalizing tank is passed through sump pump suction fine fack pond, enter aeration zone in the double-face flow-guiding pond through its dashpot top overflow again, deflector device is divided into aeration zone and negative area with the double-face flow-guiding pond, there is active sludge in the aeration zone, active sludge and water thorough mixing under the promotion of the air that aeration head sprays, in the aeration zone, fully carry out biological oxidation, increase along with aeration rate, middle part in the pond forms the current that rise, big in air deflector oxygen supply amount, after ascending current arrives the water surface, because the deadweight effect of mud makes the mud of high density deposit to the bottom, the air-flow upper punch that is risen again in this process forms and refluxes, this Circulation has been realized two purposes: one makes and stirs, and active sludge mixes with current fully; Its two, mud, sewage do not stay the dead angle.By regulating the flooding quantity implementing process control of sewage, sewage residence time in the aeration zone was generally 2.5-6 hour, sewage, mud after aeration is handled enter front flow guiding plate, mud sinks along flow deflector under the effect of deadweight, and enters the negative area by the refluxing opening of middle flow deflector bottom, because the negative area volume is generally the aeration tank more than 1/4, negative area ascending current ratio sewage settling velocity is slow, and most of mud is deposited on the skew wall by deadweight and arrives receipts mud groove through refluxing opening, discharges through sludge pump.Another part mud is therefrom gone up rising foam between flow deflector and the back flow deflector with sewage and is crossed middle flow deflector, and therefrom the crack between flow deflector and the front flow guiding plate refluxes and enters the aeration zone, and circulation participates in aeration process.This flow process is because the suction function result that the current that front flow guiding plate flows downward in the aeration tank form the backflow crack.Settling bowl rising clear water enters pump well through water conservancy diversion pond spillway.
Add the diatomite treatment agent in the clear water that double-face flow-guiding pond spillway overflows, and pressurize in the nozzle of waterpower Circulation clarifying pool bottom by water pump, this water is sprayed in nozzle, around trunnion, produce negative pressure, body refuse sucks trunnion, reaches the purpose of body refuse, diatomite treatment agent circulation promotion contact.Clear water upwards flows out, and the part sediment overstocks in the concentration compartments, regularly discharges, and another part sediment refluxes.The residence time is 1.2-2.5 hour to this equipment from inlet water to outlet water.It is to utilize body refuse in the pond and the impurity in diatomite treatment agent and the sewage to be in contact with one another, because there is uneven current potential on the surface of diatomite treatment agent, diatom and impurity are sunk rapidly, reach the isolating purpose of pollutent and water body, circulatior clarifier has the high high treating effect of throughput.
Sewage treatment process of the present invention than A-A-O sewage treatment process have that less investment, floor space are little, little power consumption, low cost and other advantages.
