Description
Technical field
The present invention relates to a kind of sewage water treatment method, particularly a kind ofly apply the method that compound microorganisms carries out polluted-water restoration of the ecosystem.
Background technology
The improvement method in the smelly river course of urban black, roughly can be summed up as Physical, chemical method and biological process, mainly take at present Physical as main.The bed mud in general river course is thicker, and in bed mud, contains a large amount of pollutents, as organic matter, nitrogen, phosphorus etc.It is open that city river is mostly, and the main source of pollution of river have two classes, and one for entering the sewage in river course, and another kind of is from bed mud, to be discharged into the pollutent of river.The method in conventional improvement river course is desilting and section dirt, and the way of desilting is to utilize the gate in river course or manually do cofferdam, by river course closed at both ends, then the method that it is mechanical that river is drained rear employing is cleaned out mud; Cut dirt and be the source of pollution that the enter river course processing of damming.
Desilting comprises machinery or the method for manually dredging, and the former can only can not tackle the problem at its root as easy supplementary means at all, and expends a large amount of manpower and materials, has little effect.Although mechanical dredging method can make local environment improve in a short time, but this method is difficult to whole thoroughly removing bed muds, and can there is not any variation to water quality in cutouts bed mud only, because remaining bed mud still can discharge pollutent in water, and can cause the phenomenon that Pollutant levels increase in a short time, until reach new dissolving and discharge balance, water quality is without any improvement, one of Nan'an District, Chongqing City regulation little pollution river, adopted integral body to change water, deep-cut the technique of mud, 7,000 ten thousand Renminbi have been spent, only 2 months rivers have just fouled again, if adopt microbiological processes to carry out polluted-water improvement, neither need to change water, also without Dredging, the quality of river water of administering after repairing can keep clean stable for a long time, no longer smelly, make river recover previous ecosystem situation.
The conventional treatment method in the smelly river course of urban black has three aspects: shortcoming:
1. the quantities of channel cleanout is large, and the cycle is long, engineering cost is high;
2. the difficulty of river channel sewage intercepting management is large, cannot implement in a short time;
3. after water correction, be difficult to keep, because open river course is difficult to stop to control pollutent, enter, administer after for some time, river course is black smelly gradually again, and forms gradually new polluted bed mud.
Adopt in the world at present the way of administering algae to mainly contain three kinds:
1. chemical process, as add chemical agent kill algae, add molysite promote phosphorus precipitation, add lime denitrogenation etc., but easily cause secondary pollution;
2. physical method, dredges bed mud, machinery except algae, diversion erosion and deposition etc., but often cures the symptoms, not the disease;
3. biological method, controls algae type biology, builds artificial swamp and aquatic vegetation as put in a suitable place to breed, and exploitation bioremediation of waters technology, is the focus of current water surrounding technology.
In the regulation of landscape lake body, adopt desilting, revetment, plant landscape and cut dirt lake body is renovated, not only engineering is complicated, and investment cost is high, and can not fundamentally improve river water burst matter and self-purification capacity.
Summary of the invention
The object of the present invention is to provide a kind of method that compound microorganisms carries out polluted-water restoration of the ecosystem of applying, the method utilizes biological restoration but can not cut completely dirty in the situation that, by bioremediation of waters and biological oxidation of sediment, can effectively eliminate eutrophication phenomenon; The method is a kind of strengthening to nature self-recovery ability, self-purification capacity, also has the advantages such as construction costs is low, running cost is low, pollution treatment is effective.
For achieving the above object, the invention provides following technical scheme:
A kind ofly apply the method that compound microorganisms carries out polluted-water restoration of the ecosystem, first from polluted-water, get a certain amount of sewage, aeration oxygen replenishing, make dissolved oxygen amount at least reach 2 mg/litre, then in got sewage, add complex microorganism thalline concentrated solution, adapt to cultivation and within 2-4 days, obtain containing bacterium sewage, complex microorganism thalline concentrated solution is 1:50-100 with the volume ratio of the sewage of getting; When adapt to cultivating, to aeration oxygen replenishing in polluted-water, make dissolved oxygen amount in polluted-water 2-4 days at least reach 2 mg/litre, and keep; To pour in polluted-water containing bacterium sewage, volume ratio containing bacterium sewage and polluted-water is 1:50-100, complex microorganism thalline concentrated solution is comprised of the following 10 kinds of thalline according to weight part: serratia: 5-15 part, photosynthetic bacterium: 5-15 part, yeast: 5-15 part, denitrifying bacterium: 5-15 part, milk-acid bacteria: 5-15 part, actinomycetes: 5-15 part, BD bacterium: 5-15 part, vinelandii: 5-15 part, nitrobacteria: 5-15 part, subtilis: 5-15 part, total plate count>=10 in complex microorganism thalline concentrated solution
9pic/ml; Until thalli growth when being about to enter decline phase, passing through again 4-8 days, to polluted-water, drop into enzyme, after 15-30 days, substantially can see that again polluted-water obviously improves, then carry out immediately the reparation of water body biologic chain, described enzyme is comprised of the following 4 kinds of enzymes according to weight part: cellulase 1-6 part, proteolytic enzyme 2-8, amylase 1-4, lipase 1-5; The injected volume of enzyme is 1-3g/m

3.
Compared with prior art, the invention has the beneficial effects as follows:
1. adopted the special multiple genus environmental microorganism strains with strengthening activity through selecting, promote the growth of a large amount of predation bacterium, increase the concentration of active sludge, the mud decrement of sewage work is become a reality, microbial bacteria group of hill is nontoxic, can decompose successful to black smelly river water body pollutent, a large amount of generations that reduce excess sludge in municipal sewage plant disposes of sewage process, and there is the function of deodorizing, do not re-use chemical floc, prevented the repeated pollution of physical environment, a large amount of operational cost of sewage work have been reduced, reduced sewage work place, management and the running cost of sewage work have been saved in a large number, in aquaculture water, the various movements of the fish shrimp crab class of degrading and the fermentation of taking advantage of remaining feed in Sediments, reduce the generation of bed mud toxic and harmful, improve water quality, reduce disease,
2. treating processes environmental protection, health, safety, be difficult for producing the stinks such as hydrogen sulfide, ammonia nitrogen;
3. the water transparency after repairing is more than 1.5 meters, and main water quality eutrophy index reaches national surface water four class water quality standard (drinking water source primary standard) (data Ke You water quality monitoring (WQM) authoritative institution measures);
4. the clearance of pair algae, total nitrogen, total phosphorus and COD is respectively 95-99%, 95-99%, 90-95%, 90-95%;
5. except accounting for the submerged vegetation of the leading self-purification function of water body recovered, other aquatic ornamental plant water lilys, lotus etc. are also resumed;
6. recovered the original part original inhabitants of water body aquatic insect spiral shell, shellfish, and part water body fish.
