Description
Technical field
The present invention relates to a kind of advanced sewage purification sterilization system, mainly can be used for various sewage are carried out the comparatively purifying treatment of the degree of depth, realize the undrinkable water reuse of water outlet.
Background technology
For common sanitary sewage and part industrial sewage, aerobic biochemical is a kind of low-cost processes mode effectively, biochemical action by the aerobic microbiological flora, organism in the water is decomposed into inorganics or simple substance, separate solid particulate matters such as mud in the water outlet and colloidal sol etc. by modes such as precipitations then, the most of impurity of in the water other also can be along with mud separating treatment together, but, aerobic biochemical is handled and generally only is adapted to the lower sewage of organic contamination concentration, for the higher sewage of concentration, then need to combine with anaerobism with aerobic, elder generation is by the effect of various anaerobic bacteria floras, the larger molecular organics that will be difficult to aerobic treatment is degraded to small organic molecule, carry out aerobic treatment again, on the other hand, still can there be certain density pollution in sewage after the aerobic treatment, be difficult to biochemical organism comprising some, also may comprise some bacteriophagees, therefore, make sewage disposal reach a higher degree of purification, just need design rational processing arrangement, each technology is connected mutually, the decontamination effect improving of finally realizing ideal.
Summary of the invention
For overcoming the above-mentioned defective of prior art, the invention provides a kind of advanced sewage purification sterilization system, the technology of this treatment system is reasonable, and treatment effect is good, the degree of purification height.
The present invention realizes that the technical scheme of above-mentioned purpose is: a kind of advanced sewage purification sterilization system, mainly comprise the anaerobic hydrolysis pond, Aerobic Pond, inclined-plate clarifying basin, the Filtration Adsorption pond, ozone oxidation pond and water collecting basin, enclosed construction is adopted in described anaerobic hydrolysis pond, be provided with the packing layer that is suspended from the middle part, pond in the described Aerobic Pond, the suction culvert in described ozone oxidation pond is provided with pump and the Venturi meter that complements one another, described pump outlet connects the import of described Venturi meter, the suction port of described Venturi meter connects the ozone gas outlet of ozonizer, described ozone oxidation pond is the catalyzed oxidation pond, is provided with the catalyst layer that is suspended from the middle part, pond in the pond.
The present invention is after the pre-treatment through necessity, at first sewage is carried out hydrolysis under the anoxic condition, under the effect of various hydrolysis floras, macromolecular organism is decomposed into easy-to-handle small organic molecule, do further processing through catalytic oxidation mode efficiently then, most organic wherein is converted to inorganics, and pollutents such as other particulate matter are adsorbed in the active sludge, after sedimentation and filtering, again by heavy metal residual in the charcoal absorption water and organism etc., at last for realizing higher degree of purification, under the effect of catalyzer, the pollutent in the water is carried out strong oxidation by ozone, carry out the oxidation sterilization simultaneously, reach the purpose of deep purifying thus, guaranteed the water quality of water outlet, made water outlet can satisfy the reuse standard of various undrinkable water.Technology of the present invention is reasonable, sewage characteristics at each step in the treating processes are selected suitable processing mode and treatment facility, not only each step all reaches its intended purposes, and all provide condition for next step processing, for example by by hydrolysis, make follow-up aerobic being achieved, by precipitation and filtration, for follow-up absorption provides favourable condition, very low through the pollutants in sewage concentration after the absorption, therefore the consumption of ozone significantly reduces in follow-up ozone oxidation and sterilization, provides good condition to reducing processing cost, effect by Venturi meter in addition, make the mixing of ozone in water very fast, mixed effect is very good, has greatly improved the actual meltage of ozone, not only help good decontamination effect improving, but also help reducing the ozone cost.
