Description

Rain sewage mouth membrane processing system

Technical Field

The utility model relates to a dirty oral membrane processing system of rain.

Background

The essence of the biological membrane treatment method is that microorganisms such as bacteria and fungi, protozoa and micro-animals such as metazoan are attached to a filter material or some carriers to grow and breed, and a membrane-shaped biological sludge-biological membrane is formed on the filter material or some carriers. In the process of contacting the sewage with the biological membrane, organic matters in the sewage are taken as nutrient substances attached to organisms and are ingested by the organisms, so that the sewage is purified. With the development of material science, the invention of various high-performance organic artificial synthetic fillers greatly improves the specific surface area and the void ratio of a biological carrier, obviously improves the effluent quality and the treatment efficiency, and obtains new development for the research and the development of a biofilm reactor.

The biological carriers are various in types, wherein suspension type fillers are wide in application, long in service life, moderate in price and quite competitive in the market, and are generally divided into soft fillers, semi-soft fillers, combined fillers, elastic fillers and the like. The soft filler has wide application, is easy to form a film, is not blocked, but is easy to tangle, agglomerate and break; the semi-soft filler is made of modified polyethylene plastics, the specific surface area of the semi-soft filler is relatively small, the central rope is easy to break, and the service life is influenced. At present, the biofilm treatment method is mainly used for treating domestic sewage, brewing and slaughtering industry and other industrial organic wastewater, the concentration of organic pollutants is high, and the water quality can be effectively improved by utilizing the action of microorganisms on a carrier. However, the mixed flow of rainwater and a small amount of rainwater and sewage has relatively low organic matter content in the sewage and large water fluctuation, and most of conventional biological fillers are synthetic materials, so that the investment is large, the biological fillers are difficult to degrade, and secondary pollution exists.

Luffa cylindrica, Luffa cylindrica (L.) Roem. After the loofah is mature, the outer layer of the loofah is removed by drying in the sun, and the internal filamentous part is the loofah pulp. The loofah sponge is a three-dimensional porous mesh (also called loofah sponge, loofah sponge and plant sponge) formed by vertically and horizontally interweaving light, tough, wear-resistant and elastic multi-layer filamentous fibers, and is in a long cylinder shape or a long spindle shape, wherein the loofah sponge is formed by drying mature loofah and removing the outer skin.

The rectangle is not strictly rectangular, and may be a shape similar to a rectangle.

As mentioned above, the utility model discloses a dirty oral membrane processing system of rain has following beneficial effect:

the vegetable sponge replaces the conventional biological streamer, mature vascular bundles are arranged inside the vegetable sponge, the vegetable sponge is natural fiber, the vegetable sponge naturally has a developed multistage pore structure, the average value of the specific surface area of the vegetable sponge can reach 123m2/g when the porosity is measured, the porous structure of the vegetable sponge not only has a good adsorption effect, but also provides attachment points for microorganisms due to the large specific surface area of the vegetable sponge. Moreover, the loofah sponge fiber is an excellent amphiphilic polymer, is mainly used for biomembrane fillers or adsorbing materials of pollutants such as heavy metals, oils and the like in the past, and has a good effect. The loofah sponge can be used for preliminarily treating suspended matters in the rainwater and sewage, so that the content of organic matters is reduced, and the function of preliminarily purifying a water body is achieved.

By adopting a micro-nano aeration mode, the aeration disc is arranged under a biofilm system consisting of vegetable sponge, and the oxidation-reduction potential of the water body can be improved by carrying out reoxygenation and stirring on the water body, thereby playing a role in reducing organic pollutants in the incoming water. Meanwhile, aeration can increase the dissolved oxygen content of the water body, promote the absorption of microorganisms on the vegetable sponge to nutrient salts such as nitrogen, phosphorus and the like, decompose and reduce the pollution load of the water body, and promote the recovery of a river ecosystem.

The soft enclosure can play a certain water blocking role in the rain and sewage discharge period so as to increase the hydraulic retention time and properly improve the purification effect of the system.
