Description

Sewage purification processing system
Technical field
The present invention relates to a kind of sewage purification processing system, mainly can be used for handling sanitary sewage and the production waste that pollution level is not really high and biodegradability is good, the water after the processing can be used as the undrinkable water reuse.
Background technology
For pollution level not really high sanitary sewage and part industrial sewage, aerobic biochemical is a kind of low-cost processes mode 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 when being back to life and production as non-quoted water, need the water after the aerobic treatment further be purified toward contact, various films are handled to separate and are used in practice, and obtained treatment effect preferably, but because the cost of film processing at present is higher relatively, influenced the development of reusing sewage, therefore the combination of various treatment technologies still is in the continuous discussion.
Summary of the invention
For overcoming the above-mentioned defective of prior art, the invention provides a kind of sewage purification processing system, the treatment effect of this treatment system is good, and cost is low.
The present invention realizes that the technical scheme of above-mentioned purpose is: comprise the settling pit that connects successively, equalizing tank, Aerobic Pond, inclined-plate clarifying basin, filtering basin and ozonize 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 ozonize 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, the front portion or the front of described settling pit are provided with grid, described equalizing tank bottom is provided with preaerator, described ozone oxidation pond is the plug-flow pond, described ozonizer adopts the plasma generator that is provided with the ozone-air outlet, and described plasma body is furnished with the high voltagehigh frequency power source circuit.
Because the present invention has adopted rational treatment process, sewage for good biodegradability, by catalytic oxidation mode efficiently organism wherein is converted to inorganics, and pollutents such as other particulate matter are adsorbed in the active sludge, remove most settleable matters in the water by inclined plate sedimentation mode efficiently then, to alleviate follow-up filtering load, further purify at filter type by high degree of purification, and then carry out ozonization and ozone oxidation, guaranteed the water quality of water outlet thus, made it to satisfy landscape water, water and pour water and multiple use such as industrial colling; Because technology of the present invention is reasonable, each step all provides condition for next step processing, reduce significantly through the impurity in the water after precipitation and the filtration, greatly reduced in ozonization and the oxidising process impurity to the absorption and the decomposition of ozone, improve the effective rate of utilization of ozone, thereby controlled required ozone amount and the processing cost of ozonize process effectively; Because the mode that has adopted jet to suck will contain in the inclusion of air water of ozone, effect by Venturi meter, make the mixing of ozone in water very fast, mixed effect is very good, greatly improved the actual meltage of ozone, strengthen the treatment effect that ozone concn in the sewage has improved ozone, strengthened the treatment effect of ozone; Owing to adopt the plug-flow pond as the ozonize pond, in the continuous propulsive process of water, form zone metastable and that gradually change, concentration at ingress's ozone is the highest, with ozone oxidation and sterilization is the principal reaction process, ozone consumes gradually and decomposes subsequently, when the plug-flow pond is enough big, ozone concn in the water part is just very low, can not cause erosion to water reuse apparatus, simultaneously, can play the effect of water collecting basin simultaneously because that the plug-flow pond can be provided with is long, from its afterbody (water part) directly water intaking can not produce material injury to the operation of system.
