Abstract
The present invention relates to a composite ecologic-oxidation method for treating domestic sewage. The composite ecologic-oxidation method for treating domestic sewage comprises the following steps: 1. making sewage flow into a sewage collecting canal through sewage pipes and inputting the sewage into a sewage collecting pond by a water-delivery pump on the tail end of the sewage collecting canal; 2. filtering the sewage in the sewage collecting pond by grillings and then sending the sewage into a filtering water pond (2) on the top of an ecologic oxidation tower (1) by a constant flow pump (6); 3. making the sewage in the filtering water pond flow downwards into a rotary ditch (3) planted with aquatic plants all year round in the ecologic oxidation tower layer by layer through a water outlet to a bottom rotary ditch; 4. making the sewage in the bottom rotary ditch flow into wetland (5) through a water outlet (4) of the ecologic oxidation tower; 5. and making the sewage from the wetland flow into natural rivers. The adoption of the composite ecologic-oxidation method has the advantages of low investment and higher efficiency of sewage treatment, and the planting of numbers of economic crops not only can bring considerable economic benefits, but also can improve environment to achieve beautiful landscapes.
Description
Technical field
The present invention relates to the domestic sewage processing method of environmental protection industry (epi), relate in particular to a kind of sanitary sewage ecology and oxidation integrated conduct method.
Background technology
Along with the continuous development of society, the raising of living standards of the people, the annual domestic consumption of our country is all increasing the increase year by year that thereupon brings the sanitary sewage quantity discharged.At present, to domestic sewage treating, the comparatively complete facility of a cover has been arranged, set up municipal treatment plant exactly, by the waste pipe of having set up sanitary sewage is gathered to the sewage-farm and to handle, reach national specified discharge standard after, emit again.Yet rural sewage and sanitary sewage to the generation of vast Rural areas, owing to be subjected to the influence of rural area objective condition, rural sewage that produces and sanitary sewage exist pollution dispersion, pollution composition complexity, contamination level is big and uppity characteristics, is not very desirable if indiscriminately imitate domestic sewage treating method effect.To this, a large amount of rural sewages and sanitary sewage are often without any processing, just directly be discharged in the natural river course, so not only can pollute natural river course, and these contaminated natural river courses can become the source of the pollution of area source of great river, lake pollution and eutrophication, cause serious environmental issue.Some Rural areas adopts traditional septic tank that sanitary sewage is handled, but by analysis, nutritive elements such as the organic compound of the overwhelming majority and nitrogen, phosphorus all will finally enter natural river course by the infiltration and the absorption of soil; And by the solids component that picked up through natural fertilising, major part also will import natural river course along with rainwash.Adopt the processing of septic tank can not reach the purpose of the various nutritive ingredients of effective removal thus, the discharging of some gas with foreign flavor also can impact surrounding environment in the septic tank simultaneously.
Summary of the invention
The present invention has overcome the not good defective of treatment effect that exists in original domestic sewage in rural areas by using processing, and a kind of sanitary sewage ecology and oxidation integrated conduct method are provided.This sanitary sewage ecology and oxidation integrated conduct method combine Ecological Disposal with oxide treatment, can not only reach the corresponding effect that domestic sewage in rural areas by using is handled, and less investment, view are good.
The present invention is achieved in that and the invention provides a kind of biological oxidation tower, and this biological oxidation tower is the tower structure, and its top is retention basin to the recess of inside center, and the periphery successively is provided with the ditch that circles round, at retention basin with circle round and be the media storage groove between ditch; Bottom and bottom around the retention basin are barrier.
Above-mentioned biological oxidation tower is provided with the aisle in its underpart to top.
The above-mentioned biological oxidation tower retention basin of portion within it is provided with lid.
Water outlet on every layer of ditch that circles round of above-mentioned biological oxidation tower is one or more.
The sanitary sewage ecology and the oxidation integrated conduct method that on above-mentioned biological oxidation column foot plinth, carry out, this sanitary sewage ecology and oxidation integrated conduct method may further comprise the steps:
Step 1, sewage flow into the combined sewage canal through waste pipe, and import sewage collecting pool through the water transfer pump of interflow sewer end;
Sewage in step 2, the sewage collecting pool is behind the barrier drainage, by the retention basin of constant flow pump in the water-in of biological oxidation top of tower is delivered to the biological oxidation tower;
Sewage in the step 3, retention basin is successively flowed into downwards to plant in the biological oxidation tower by biological oxidation tower top water outlet after dielectric surface microbiological oxidation disaggregating treatment and is implanted with Lu Sheng and the ditch that circles round of hygrophyte all the year round all the year round, in the undermost ditch that circles round;
In the sanitary sewage ecology and oxidation integrated conduct method of carrying out on above-mentioned biological oxidation column foot plinth, the medium in the media storage groove is sand setting, gravel, cultivation ball and coral section.
Principle of the present invention is: physics, chemistry and bioremediation are combined, carry out comprehensive sanitary sewage disposal.In sewage collecting pool, sanitary sewage is carried out primary treatment, utilize physical sedimentation, dielectric surface microbiological oxidation disaggregating treatment and adsorption to remove wherein precipitable solid, colloid, nitrogen, heavy metal, phosphorus, BOD
5, bacterium, virus and insoluble organic matter; Then sewage is sent into the biological oxidation tower and carried out further chemistry and biological treatment, in the filtered water reservoir of biological oxidation tower, pass through the oxidation of chemistry, reduction, phosphorus is further removed in cohesion and adsorption, heavy metal and insoluble organic matter, pass through the filtration successively of the ditch that circles round in the biological oxidation tower again, utilize microbial metabolism, digestion of oxidation and bacterium and anti-digestion, reach hygrophyte all the year round by the Lu Sheng all the year round that in the ditch that circles round, plants simultaneously, as Canna generalis Bailey, peppermint, jacinthe, reed, Herba Eichhorniae, romaine lettuce, turfgrass, Herba Eichhorniae, frogbit, water caltrop, Scirpus tabernaemontani, Rhizome of Grass leaf Sweelflag, cattail, ivy, hornwort, wild arrowhead, the sorption of water caltrop etc. is further removed BOD again
5, nitrogen, phosphorus, colloid, insoluble organic matter and heavy metal; Through the over-wet land, utilize physics, chemistry and the biological action of wetland mesostroma, waterplant and microorganism at last, make the purification of water quality that enters the river course, reach emission standard.Adopt the present invention to carry out the processing of sanitary sewage, can produce following effect: less investment; Save and plough; Sewage treating efficiency is higher, can reach the standard of the above discharging of national II class water quality; By the plantation of some cash crop, not only comparatively considerable economic can be brought in the future, and environment can be improved, view is good.
