Bar river becomes billabong.
The water pollution situation of China is equally very severe, due to fund and technology, there are substantial amounts of sanitary wastewater and industrial wastewater not just to be directly discharged into water body by treatment daily, cause rivers and lakes to be subject to serious pollution, at present, China has been detected by
78
Bar has had in river
54
Bar is subject to serious pollution.With developing rapidly for China's economic, people's living standard is improved, and domestic water and industrial water consumption increase sharply, but the development speed of water technology does not catch up with the rate of economic development, so that Chinese water shortage situation grows in intensity, shortage of water resources problem has turned into the problem that China primarily solves.
With society and expanding economy, miscellaneous chemical products are mass produced out, at the same time, substantial amounts of wastewater from chemical industry is also drained into environment, sustainable development to society causes serious threat, the environment that we live is influenceed by the industries such as chemical industry, medicine, dyestuff institute waste discharge, and water pollution situation is increasingly severe, and current Environmental Scientific Research personnel are just paying close attention to the research of wastewater processing technology.Kind of waste water includes industrial wastewater, the major class of sanitary wastewater two; wherein lavatory, kitchen, bathing etc. belongs to sanitary wastewater by the waste water that Human routine activities are discharged; and industrial wastewater refers to factory produces the various waste water for giving off in process of production; the complicated component of industrial wastewater, species is various, for example; phenol wastewater; heavy metal wastewater thereby, sulfur-containing waste water, cyanide wastewater etc..
Ozone high grade oxidation technology be grow up this year enjoy a kind of water process new technology of concern, using the hydroxyl radical free radical of the strong oxidizing property for producing during the course of the reaction（·
OH
）The organic pollution in waste water is gone to carry out oxidation Decomposition as main oxidant.Patent name is a kind of Two-way Cycle catalysis ozone water treatment facilities（Publication No.
CN103058433B
）Chinese invention patent, disclose a kind of Two-way Cycle catalysis ozone water treatment facilities, including outer barrel, middle cylinder, inner cylinder, uviol lamp, ozonated air distributor and gas-liquid-solid separator, it is characterised in that：The outer barrel, middle cylinder and inner cylinder are set with one heart, and the bottom of outer barrel sets base plate, and the top of outer barrel sets water inlet；The lower edge of the inner cylinder is fixed on outer tube end plate, on the top and bottom of inner tube wall, some bar holes are circumferentially placed equidistant respectively along barrel, screen cloth is set with outside the bar hole on inner cylinder top, the setting upper cover plate suitable for reading of inner cylinder, sets centre bore on upper cover plate, be also evenly equipped with the circumference with centre bore as the center of circle and centre bore specification identical circular hole, insertion is cased with the uviol lamp of quartz glass sleeve respectively in centre bore and circular hole, and being cased with centre bore is also cased with outside the uviol lamp of quartz glass sleeve
TiO2
Net cylinder；
If placing dried layer porcelain ball on the base plate between above-mentioned outer barrel and inner cylinder, if the total height of dried layer porcelain ball is higher than the top of inner cylinder bottom bar hole；The upper edge of the middle cylinder is following less than inner cylinder top bar hole, gap is left between the lower edge and porcelain ball of middle cylinder, ozonated air distributor, the flange suitable for reading connection gas-liquid-solid separator of outer barrel are set in the bottom of middle cylinder, the annular space between middle cylinder and inner cylinder；The gas-liquid-solid separator, including matrix, outer sleeve, baffling cylinder and separating tube, the matrix of separator is the tapered cylinder in bottom, top, the upper edge less than inner cylinder of the upper edge higher than the bar hole on inner cylinder top of matrix；Outer sleeve is set outside above-mentioned matrix, endless groove is surrounded between outer sleeve and matrix outer wall, the side wall of outer sleeve sets delivery port, upper edge of the delivery port less than matrix；The fixed and body concentric baffling cylinder of base in matrix, the upper edge of the upper edge higher than matrix of baffling cylinder, the upper edge of the lower edge less than matrix of baffling cylinder；Separating tube is fixed in baffling cylinder with one heart, separates the bottom outward bending of barrel, the upper edge of the lower edge less than middle cylinder of separating tube, upper edge, the lower edge higher than baffling cylinder of the upper edge less than matrix of separating tube, the diameter of the lower port diameter more than baffling cylinder of separating tube；Activated carbon is also filled with device.Wastewater treatment efficiency is not fine in the art solutions, if necessary to treatment effect is put on, must dosage so that cost increases, the cost of sewage disposal is too big.
And then occur in that a kind of aeration and biological processing method, biological aerated filter process extensive use at home and abroad, technical maturity, the main microorganism using accompanying growth on filler in reactor carries out biodegradation to the pollutant in waste water, filler and biomembrane can play absorption detention effect, and form the denitrification that food chain is classified microenvironment and anaerobism section inside predation, and biomembrane along water (flow) direction.BAF is compared with traditional activated sludge process, with strong, the biodegradable effect of disposal ability it is good, influenceed that small, impact resistance ability is strong, do not need the process advantages such as second pond by temperature, be one of denitrification dephosphorization technique the most cost-effective in current water technology.A kind of entitled strengthened denitrification
