Description

A kind of high-efficiency activated thermopnore clarifier
Technical field
The present invention relates to a kind of city sewage deep treatment water purifier, is a kind of high-efficiency activated thermopnore clarifier specifically.
Background technology
Urban sewage treatment process and process structures and Type of equipment selected are the important steps of Wastewater Treatment Design.Determine that the Main Basis of sewage treatment process is the degree for the treatment of reached required for sewage, degree for the treatment of then depends on the whereabouts of the rear water outlet of process.If the water outlet after process enters water body, then the degree for the treatment of of sewage should make full use of water body self-purification ability, and anti-water-stop body is polluted again.If the water outlet after process is back to industrial enterprise or urban construction, two kinds of situations be considered: direct reuse; Do some supplement process after row reuse again.Sewage disposal is generally remove BOD(biochemical oxygen demand (BOD)) material is as main target.In large-scale wastewater treatment plant, many employings are to be precipitated as the sewage coagulation at center and the sewage second-level process centered by biological treatment, in order to remove the materials such as nitrogen, phosphorus, COD further, really reach using water wisely, reduce blowdown, by the operating Mode of Circular Economy realizing minimizing, recycling, recirculation (3R) in water, be that China's advanced treatment of wastewater technology improves the more and more urgent task faced.Sewerage advanced treatment process traditional at present: 1, physical-chemical process 1. machinery dam.The simplest mechanical closure method is filtered, and simple filtration adopts quartz sand to be filtrate usually, has good removal to suspension and colloid, and turbidity, the SS of water outlet are usually lower, also have certain effect to COD and colourity.2. chemical precipitation.Coagulation-settlement process is technique the most frequently used in advanced treatment of wastewater, and the most of Sewage Plant of China all adopts the method in advanced treatment process.3. chemical oxidation.Chemical oxidation is the basis of various high-level oxidation technology, and it uses chemical oxidizing agent oxidize the contaminants into micro-poison, harmless material or change into tractable form.4. ion-exchange: ion exchange resin is in different field extensive use.2, biological method: utilize microorganism self can carry out decomposing the characteristic absorbing produce power and nutriment to materials such as organic matter, nitrogen-containing compound, phosphorus-containing compounds, turn out some specific microorganism, polluter in utilizing their this feature to dispose of sewage, reaches the object to purification of water quality.3, physical chemistry and life assemblage method: due to pollutant load still very high, the composition also more complicated had in the biological secondary effluent of Sewage Plant, therefore in the process of advanced treating, no matter be independent physico-chemical process, or bioanalysis is all difficult to make water outlet reach national recycle water standard separately, general independent technique is hit load-bearing capacity difference, sometimes in order to make effluent quality improve, cost even can increase several times.4, BAF: biological aerated filter process (being called for short BAF) is the third generation sewage disposal biofilm reactor after drip filter tank and dry filtration system, it has given full play to the classification predation of food chain in biological metabolism effect, physical filtering effect, the physisorption of biomembrane and filler and reactor, not only there is technology of biological membrane advantage, also play the effect of filter tank, effective space simultaneously.5, Electro Sorb technology (EST): adopt Carbon Materials to adsorb in a large number for the process of waste water in producing at present and carry out removing of heavy metal ion, organic pollution and coloring matter, that applies mainly contains active carbon, comprises granular active carbon and fibrous activated carbon.But all there is some problems in above various technology in the strength of materials, service life, contamination resistance, throughput requirements, cleaning etc.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of integration, floor space is little, avoid the deviation in the different installation process of structural material, shorten the construction period, overcome the difficulty of northern frore area civil engineering in winter; By changing active filter material, filtering layer, solve the high-efficiency activated thermopnore clarifier that the too low poor filtration effect of filtering layer and filtering layer too high blocking washer sand export etc. affect the common fault of effluent quality.
