Abstract
The invention discloses a new rain water treating technique-a road biological treatment method. In the technique, a biological filter material containing microorganisms is put under a penetrable road and a moist layer; a matrix mixed by stone, mineral slag, ceramisite and the like, according to certain grade is mixed with the microorganisms so as to produce special biological filter material roadbed for rain water treatment; and when rain water flows through the penetrable road, the pollutant in the rain water can be treated under the biochemical effect of the microorganisms, thereby realizing the effect of purifying water. Without influencing road function, the purification treatment, collection and reuse of road rain water in urban roads, squares, parking lots and the like are realized. The method pertains to the field of environment-friendly water treatment.
Description
Technical field:
The present invention relates to a kind of rainwater New Process for Treatment----road biological treatment, belong to field of environment protection.
Background technology:
Urban construction at present causes hard surface to increase, and rainfall is washed away a large amount of pollutents and gone into the river, and the unprocessed water surrounding that directly enters of this part pollutent endangers bigger to urban environment.With regard to Beijing, at least 2.7 ten thousand tons of the COD amount of annual face of land rainfall through miscarrying living.Rainy season, the pollutent in rainwater inflow stream, lake increased gradually, and serious wawter bloom has appearred in annual river in summer lake.The processing of urban rainwater, the utilization of urban rainwater safety has been urgent problem.
Summary of the invention:
Now Fa Ming purpose provides a kind of rainwater New Process for Treatment----road biological treatment: hard surface is changed into perviousness ground; On the perviousness road surface with preserve moisture and lay biofilter material under the layer as the rainwater processing layer, rainwater is flowed through, and water pollutant obtains treatment and purification under the biochemical action of microorganism behind the perviousness biofilter material road surface.Rainwater New Process for Treatment----road biological treatment can be cut down the city surface source pollution that urban rainwater causes, and realizes the rainwater processing of hard surfaces such as urban road, square, parking lot, the order ground of collecting, utilizing.It is a kind of novel process that water pollutes that reduces.
Another object of the present invention provides a kind of manufacture method that contains the microorganism biological filtrate.Rainwater is handled its feature 1 of biofilter material and is: place filter material layer top by aerobic microbiological, anaerobion, the oxygen animalcule of holding concurrently with mix such as building stones, slag, haydite or with microorganism.Rainwater is handled its feature 2 of biofilter material, is biofilter material and an amount of cement, sand, starch, glue mix, is pressed among brick or placement basket in bulk, the cage by molding apparatus, also can disperse to lay underground.
A further object of the present invention is that the layer material of preserving moisture selects the different-grain diameter sand grains at the perviousness subsurface setting layer of preserving moisture, and the existence that guarantees microorganism is with active.
Description of drawings:
Fig. 1 rainwater New Process for Treatment----road biological treatment flow process
Fig. 2 road biological treatment implementation method
Embodiment:
The perviousness road surface adopts permeable brick or other penetration material to lay, and the layer of preserving moisture is set under the perviousness road surface, and the existence that guarantees microorganism is with active.On perviousness ground with preserve moisture and lay rainwater under the layer and handle biofilter material, lay available biofilter material brick, filtrate in bulk can disperse to lay underground, also can disperse to place lay among basket, the cage underground.
The road bioremediation, it is as follows that rainwater is handled the biofilter material embodiment: building stones, slag or haydite, its particle diameter 10-30mm clean with clear water, between pH value=6-9.That microorganism is adopted is aerobic, anaerobism, the oxygen microorganism placement amount of holding concurrently are suitably adjusted.Make the biofilter material brick, need to increase cement.Sand and starch, glue mix form by mould and mechanical means compacting.Rainwater is handled biofilter material, need imbed 15-20cm under permeable brick or other infiltration road surface during use, laying depth 0.3-0.8m.
Under the rainwater New Process for Treatment roadbed perforated tube material being set should be corrosion-resistant, the pipeline that intensity is high, and rainwater can be gone into well after the collection and purification, and ponds etc. store and utilize.
Claims (7)
1, rainwater New Process for Treatment----road biological treatment is under the road infiltration road surface and the layer of preserving moisture, and does special-purpose roadbed by the rainwater processing filtrate that the matrix and an amount of microbial population of certain grating are formed.Rainwater is incorporated well into after being provided with the perforated tube collection and purification under the roadbed, and pond etc. store and utilize.The road biological treatment can accomplish that rainwater processing collection utilizes the effect of purification of water quality again.
2, according to right 1 require, microorganism is present in stromal surface or the inner rainwater of forming and handles filtrate and do special-purpose roadbed in rainwater New Process for Treatment----the road biological treatment.
3, described rainwater according to claim 1 feature that exists of handling filtrate can be pressed into brick by molding apparatus by matrix and microorganism, or with among filtrate basket in bulk or the cage, also can loose is laid on the underground biological filtering layer roadbed of doing.
4,, rainwater 1 described according to right handled biofilter material layer roadbed, and the contained microorganism of its feature request is aerobic, anaerobism, the oxygen animalcule of holding concurrently.
5, it is characterized in that power 2, the 3 described filtrates that microorganism is arranged according to right 4 methods described, microorganism ecological environment, be layed in the infiltration road surface and preserve moisture layer down, in the wet environment.
6, according to right 4 described, rainwater processing biofilter materials, be fit to handle organic contamination water quality and part of contaminated water in the rainwater.
7, under, the rainwater New Process for Treatment roadbed 1 described according to right the perforated tube material being set should be corrosion-resistant, the pipeline that intensity is high, and rainwater can be gone into well after the collection and purification, and ponds etc. store and utilize.
