Problems solved by technology

[0002] At present, urban construction has led to an increase in hardened road surfaces, and rainfall has washed away a large amount of pollutants into the river. These pollutants are directly discharged into the water environment without treatment, which is harmful to the urban environment.

Embodiment Construction

[0008] The permeable pavement is paved with permeable bricks or other permeable materials, and a moisturizing layer is set under the permeable pavement to ensure the survival and activity of microorganisms. Lay rainwater treatment biological filter materials under the permeable ground and moisture-retaining layer, and lay available biological filter material bricks. Bulk filter materials can be spread underground, or placed in baskets and cages.

[0009] The road biological treatment method, the implementation example of rainwater treatment biological filter material is as follows: stone, slag, or ceramsite, the particle size of which is 10-30mm is washed with water, and the pH value is between 6-9. Microorganisms are appropriately adjusted with the amount of aerobic, anaerobic, and facultative microorganisms. To make biological filter bricks, cement needs to be added. Sand, starch and glue are mixed and pressed through molds and mechanical equipment. The biological filter m...

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: [0001] The invention relates to a new technology of rainwater treatment - road biological treatment method, which belongs to the field of environmental protection. Background technique: [0002] At present, urban construction has led to an increase in hardened road surfaces, and rainfall washes away a large amount of pollutants into rivers. This part of pollutants is directly discharged into the water environment without treatment, which is harmful to the urban environment. As far as Beijing is concerned, the amount of COD produced by surface rainfall through flow is at least 27,000 tons every year. Pollutants from rainwater flowing into rivers and lakes during the rainy season have gradually increased, and serious algal blooms have appeared in rivers and lakes every summer. The treatment of urban rainwater and the safe use of urban rainwater are urgent problems to be solved. Invention content: [0003] The purpose of the present invention is to provide ...
