Description
Technical field
The utility model relates to a kind of sewage-treatment plants, are specifically related to a kind of floated for polluted water body processing
Purified in situ processing unit, belong to basin water pollution Treatment process field.
Background technique
With the progress of society and the development of science and technology, the excessive interference of the mankind destroys the aquatic environment of river system, greatly
The pollutant of amount enters water body, causes water environment index degradation, causes the ability of the river self-purification decline, water quality deterioration, water body
The problems such as eutrophication, does great harm to the environment, it is necessary to carry out purification treatment to polluted water body.
Existing purification treatment method mainly has physical method, chemical method and three kinds of biological method.Physical method is to pollution
Object removal is not thorough, and chemical method can introduce new chemical substance, and bioanalysis is the metabolism using microorganism, is made in sewage
Organic pollutant oxidative degradation is at the method for innocuous substance, and investment is small, and effect is obvious, using most.
In bioanalysis, and it is divided into dystopy purification and two kinds of technologies of purified in situ.Dystopy purification is by sewage from polluted water
Body is drawn to sewage-treatment plant, flows back to raw water body after processing again.Method investment is big, increases facility complex management, operation cost newly
Height, and the water body purification of large watershed can not be suitable for.Purified in situ technology in biological method purification purifies thorough, processing dirt with it
The advantages such as dye species are more, operation cost is low are widely used in water pollution field of purification.
It common are 3 kinds in bioanalysis purified in situ technology, the absorption one is the root system using plant to nutrition, removal
Pollutant, but the method is larger to plant-independent, it again can polluted-water after plant dies or root system rots；Another kind be add it is micro-
Biological inoculum, using the pollutant in microorganism decomposition water, but the carrier that the method microorganism is not fixed, it is flowed out with water flow, benefit
It is low with rate, need continual add；Another is the biofilm simulated in sewage treatment, and implantation is Filamentous artificial in water
Fiber provides growing carrier for microorganism, by the pollutant being attached in the microorganism decomposition water on staple fibre surface, has
Microbe species multiplicity, growth stablize, good purification, can landscape the characteristics of.
Application No. is 201420006519.6 Chinese patents to disclose a kind of water plant formula river water body purification device.But it should
