Description
Technical field
The present invention relates to water surrounding restoration of the ecosystem field, relate in particular to a kind of town and country polluted river channel water body efficient combined-type recovery technique.
Background technology
Along with China's rapid development of economy, China's water environmental problems becomes increasingly conspicuous, and the town and country water surrounding suffers from unprecedented threat.Existing investigation shows that Yangtze River Delta Region town and country water surrounding ecology lost basic function more than 90%, the river course, town and country is because of polluting and ecosystem serious degradation, river water quality is in V class and bad V class water quality substantially, most river water bodies are seriously polluted, eutrophication, blackening foul, pathogenic bacteria exceeds standard, cause severe environmental ecology situation, had a strong impact on ecology, production and the living safety in town and country.Thereby be the major issue that needs to be resolved hurrily to the reparation of town and country water surrounding.
Physics ruling by law reason pollution of river water body mainly is meant by cutting technology such as dirty desilting, environment water transfer and aeration aerating to be administered.The physics method can only be applicable to that generally the control point-source pollution is main river course, the river course of pollution in wide area is difficult to control, and this methods engineering is huge, and cost is higher, also may destroy aquatic ecosystem.
Adopt ecological matrix and filler biofilm method also can play certain interception function to source of pollution.Ecological matrix and filler essence are a kind of carriers of immobilized microorganism technique.Immobilized microorganism technique promptly is that microorganism is fixed on the biotechnology that makes its highly dense on the carrier and keep its bioactive functions, its principle is for assembling and breed the microflora of certain biomass on carrier, metabolism by microorganism is removed pollutants in sewage, simultaneously pollutent is played certain interception function.Low, simple to operate, the easy maintenance of this method less investment, energy consumption and running cost, organism in the water body, nitrogen phosphorus, heavy metal, algae and suspended particle etc. all there are the removal effect, but need just can obtain effect preferably in conjunction with the common purifying water body of additive method.
The microbial augmentation restorative procedure is to adopt microbiobacterial agent to purify water, contain in the microbiobacterial agent through having of screening domestication and strengthen microorganism of repairing function of water body and the nutritive ingredient that promotes its growth, can quicken microbial growth in the purification of water quality process, promote organic degraded in the water body, can significantly remove ammonia nitrogen, pollutents such as phosphorus, and can significantly promote water body dissolved oxygen and transparency, but in water body, run off easily, especially in dynamic waters, river course, if use its purifying water body effect of microbial augmentation recovery technique desirable not to the utmost separately, need be in conjunction with additive method purifying water body water quality.
Ecological floating island is meant by the waterplant of cultivating on the buoyancy aid, effect by microorganism on plant and the root system thereof etc., directly from water body, absorb nutritive substance and other pollutents, thereby eutrophy composition such as the nitrogen phosphorus in the removal water body and reduce multiple pollutant load in the water body, reach the purpose that purifies water, simultaneously, waterplant and algae grows form competition, suppress algae and carry out photosynthesis etc., thereby suppress or reduce the probability of " wawter bloom " generation, but single chinampa its effect of purifying water body of using is also limited, and has limitation for the decontamination effect improving than the deepwater field water body.In water body, throw in the filter-feeding hydrocoles, can reduce the breeding of algae in the water body, not only can purify water, can also set up a stable ecosystem.
Publication number is CN102010071A, the disclosure of the Invention file that name is called " a kind of combination high-efficiency riverway water quality purification technology " discloses a kind of technology that adopts bacteria bed, bacteria agent method, waterplant chinampa, hydrocoles purifying method to come the filtration, purification water body simultaneously, but there is following defective in actual use in it: 1, do not utilize solar energy aeration, and can not provide sufficient oxygen for the growth of the microorganism in the water body and hydrocoles; 2, not using microbial compound preparation, promptly is not composite the forming of specified proportion according to three kinds of microorganisms and three kinds of enzymes, organism and pollution substance so it can not comprehensively be degraded fast in the water body, and purification and regulation effect are good inadequately; 3, the method that does not adopt ecological matrix and filler to combine can not provide more competent growth, breeding place for microorganism, and treatment cost is higher.Simultaneously, also there is permanganate indices (COD in this technology
Mn) clearance, ammonia nitrogen degradation rate, the not high enough defective of total nitrogen degradation rate.
Summary of the invention
The objective of the invention is to overcome the prior art above shortcomings, a kind of municipal pollution river water body efficient combined-type recovery technique is provided, comprehensive utilization sun power micro-pore aeration technology, ecological matrix, microbe-enzymatic complex intensifying recovery technique and methods such as ecological floating island and input hydrocoles reduce organism and other pollutents such as nitrogen phosphorus in the water body, purify river water body, optimize aquatic ecosystem, reach the effect of optimizing view simultaneously.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of municipal pollution river water body efficient combined-type recovery technique, take following measure to purify river water quality simultaneously:
In the bottom, river course ecological matrix, the 0.5%-1% of the ecological fiduciary point river course total area are set;
Be arranged alternately ecological floating island in the both sides, river course, ecological floating island accounts for the 6%-25% of the river course total area; Ecological floating island is arranged alternately in the both sides, river course every 5-7 rice;
When the dissolved oxygen in the river water body is lower than 2mg/L, the solar energy aeration machine is set at interval at the middle part, river course; Solar energy aeration machine spacing distance is a 50-100 rice.
In the river course, throw in hydrocoles and come purifying water body;
