Description
Technical field
The invention belongs to technical field of sewage, relate to the method and the device of a kind of lake water pollution prevention and improvement particularly
Background technology
China's rivers and lakes 70% are contaminated at present, lake atrophy, functional deterioration, water pollution, and the lake ecosystem structure wrecks, overbalance.In the world, lake, particularly shallow lake, water pollution prevention and improvement also are difficult problems.Lake water pollutes and mainly contains following reason:
1) since the lake have enrich water resources, having driven lake Economic development on every side and urban population constantly increases, production and domestic water also roll up, when the lake region water consumption surpasses the lake water magnitude of recruitment, cause lake level decline, lake surface atrophy, wetland minimizing, environment variation, organic supporting capacity and the self-cleaning ability that enters in the lake reduced.
2) a large amount of undressed waste water of industrial enterprise, breeding enterprise and urban life, the sewage around the lake is discharged in the lake, causes lake water pollution and eutrophication.Waterplant hypertrophy in such waters causes water oxygen level to reduce, and makes water putrid and deteriorated.
3) water in lake is mobile poor, near shallow water and the arm of lake zone the loke shore particularly, and water is mobile, the nutritive substance enrichment in the water, the oxygen level of water not only can not get improving but also by the nutritive substance consumption in the water and lower.The reduction of oxygen level promotes the growth of the anaerob in the water conversely.Under the acting in conjunction of these factors, the water quality eutrophication becomes a pool of stagnant water at last.
4) enter waste water in the lake, the contained organic pollutant of sewage deposits for a long time, forms mud at lakebed.When summer run into the weather sweltering heat, daylight shines for a long time, when water temperature raises, lakebed mud decomposes, and discharge eutrophication materials such as a large amount of ammonia, nitrogen, various organism such as microorganism in the lake water, algae are bred in a large number, lake water quality rapid deterioration causes sudden water pollution, has a strong impact on enterprise's production and life of urban resident around the lake.
Traditional lake water pollution control, often adopt that water transfer drainage, machinery are salvaged, the plantation pasture and water, breed fish, microorganism is dropped into etc., aforesaid method in application process, weakness such as have DeGrain, processing costs height, cure the symptoms, not the disease.
The water pollution problems that whether can adopt following method prevention and administer the lake:
1) reduces the quantity of from the lake, fetching water quantity and in lake water, discharging organic pollutant
Depths reason back reuse is carried out in industry around the lake and aquaculture waste water, city and domestic sewage in rural areas by using etc., reduced the quantity of from the lake, fetching water on the one hand, increase the water storage in lake, improve the supporting capacity of lake water organic pollutant.Reduce the pollutent that enters in the lake on the other hand, reduce organic content in the lake water.
2) allow the water in Polluted area or the water quality inferiority waters flow
Waters at Polluted area or water quality inferiority is provided with intake, the circularly purifying treatment facility is installed, lake water is extracted from an end multiple spot by certain water yield, through after the purifying treatment, be transported to the edge in the waters of intake opposite, Polluted area or water quality inferiority, upwards and to the intake direction spray, the power that utilizes jet of water to produce, the water in the waters of polluted waters or water quality inferiority is flowed, strengthen lake water simultaneously and contact, increase the oxygen level of lake water with air.The self-cleaning ability of water derives from the oxygen level in the water.The water smoke of mobile water and ejection can increase the oxygen level of water, promotes that the organic pollutant in the water decomposes.The mobile pollutent that makes of water can enrichment simultaneously.
3) content of organic pollutant in the reduction lake water recovers the lake ecological balance
The water in the zone of lake water pollution or the waters of water quality inferiority is in the process of carrying out circular treatment, adopt filtering adsorbing material, remove part organic pollutant, heavy metal etc. in the lake water by Filtration Adsorption, reduced the content of water pollutant, improve the self-purification capacity of polluted waters and, recover the lake ecological balance the degradation capability of pollutent.
4) water of control burst pollutes and takes place
Motor-driven water treatment equipment is set, when local waters burst water pollutes, in the shortest time in the lake region, motor-driven water treating equipment are transported to the polluted waters scene, in time, purify effectively, circular treatment, control and decontamination source avoid pollution face to spread.
5) organic pollutant is changed into available resource, avoid the pollutent circulation.
Adopt organism pyrolysis processing equipment, the organic pollutant of the removal in the lake water disinfection treating processes, the waterplant of salvaging, the mud of cleaning are carried out pyrolysis processing, change into water of condensation, inflammable gas and carbide.Water of condensation is used for industrial production, inflammable gas is used for organic pollutant, waterplant, the required thermal source of mud pyrolytic process.Carbide is used for lake water processing and lake soil improvement on every side.
Aforesaid method does not appear in the newspapers so far.
