Abstract
An energy-saving active biomembrane for treating sewage is prepared through coating the mixture of active microbes and high-molecular polymer's derivative on the surfaces of the surficial solid filler and high-toughness non-woven cloth medium. When the sewage is flowing through the surface of said medium, the microbes are growing and reproducing to form a biomembrane with surficial aerobic layer and internal anaerobic layer. As a result, whole memembrane is growing, then dropped and finally updated by absorbing the organic substances as nutrients, so degrading the pollutents in sewage.
Description
Technical field the present invention relates to a kind of economical active biological membrane by water treatment.Select the mixture of the derivative of living microorganism, high molecular polymer, adopt modern biotechnology, the bag quilt is in the solid surface filtrate, and high tenacity non-woven fabrics medium is made multi-layer energy-saving type active biological membrane by water treatment.Can reduce the content of materials such as COD, BOD5 in the water, ammonia nitrogen rapidly, efficiently; It can also suppress the generation of stink substances such as indoles, thiolate, skatole, thereby removes peculiar smell; In the final stage of sewage disposal, use this product will help separating of mud and water, shorten dwell time of sewage, and effluent quality is cleaned more.Easy to use, directly be added in the water body and get final product, do not need additionally to increase facility, save energy has been saved the input of fund.Product is also non-corrosiveness of nontoxicity both, more nonstaining property, its use is without any special requirement or avoid the scope of using.Water is base substance and the necessary environmental factors that the mankind depend on for existence, along with the raising of industrial high development and people's living standard, development of urbanization, the quantity discharged of municipal wastewater is increasing, water quality also changes to some extent, and compound novel, difficult degradation occurs often.These factors all might make the operation generation problem of municipal wastewater treatment plant, show that the water yield exceeds the Sewage Plant processing power or effluent quality is not up to standard, even phenomenons such as sludge bulking, mud poisoning take place.There are a large amount of industrial solid castoffs, domestic refuse, waste water in annual China, float the dirt sediment, also has certain chemical fertilizer and agricultural chemicals in batches to immerse soil in addition.These pollutents from ground, aerial polluted source water source.Problems such as quality problem water pollution are serious day by day.Become the major issue of countries in the world.Therefore, people's strong request obtains to meet the water of source water water quality standard, reduces the various diseases that brings owing to serious day by day environmental pollution water source, and this has become people's strong actual requirement.Existing water-treated prod is a lot, and performance differs, effect is single, scarcely desirable, and power consumption during these products work, power consumption, costly.Therefore, people wish to have a kind of safe and reliable always, again the active biological membrane by water treatment of environmental protection and energy saving.
Background technology the object of the present invention is to provide a kind of safe and reliable, economical active biological membrane by water treatment, have following characteristics: (1) is attached to the lip-deep microorganism of solid dielectric to the water yield, the variation of water quality has stronger adaptability. and (2) solid dielectric is beneficial to microorganism and forms stable ecosystem, the kind of perching microorganism is more, the processing efficiency height. (3) degraded product sludge quantity is few. (4) convenient management. on basis without electric energy, by the multilayer active biological film, can provide the water that meets the source water water quality standard.
Summary of the invention main points of the present invention are to select suitable component, adopt modern biotechnology to form a kind of economical active biological membrane by water treatment.
The prescription that the present invention selects is as follows: living microorganism culture 5-8 kind; The derivative 10-20% of high molecular polymer; High tenacity non-woven fabrics medium is made biomembranous thickness 2～3mm..
Microbial film is to rely on to be attached to the solid surface filtrate, on the medium of high tenacity non-woven fabrics and the organic aerobic treatment method of the microbially decontaminate of growth and breeding, by means of the biofilm medium, when organic waste water flows through dielectric surface, microorganism is in its surface growth breeding, form microbial film, the surface of film is dissolved with more dissolved oxygen, form aerobic layer, the internal layer dissolved oxygen of film is less, easily forms anaerobic layer, and whole film is in growth, the ecosystem that comes off and upgrade. the microbial growth metabolism is done nutrition with the organism in the sewage, thereby makes pollutent obtain degraded.
The preparation method of product of the present invention is:
1). 5-8 kind living microorganism is increased bacterium cultivate.
2). with culture, mix mutually with the derivative of high molecular polymer.
3) mixture modern biotechnology, bag be by in the solid surface filtrate, and high tenacity non-woven fabrics medium is made the economical active biological membrane by water treatment of multilayer different shapes, different size.
The present invention compares with existing products and has the following advantages:: (1) is attached to the lip-deep microorganism of solid dielectric to the water yield, and the variation of water quality has stronger adaptability.Can reduce the content of materials such as COD, BOD5 in the water, ammonia nitrogen rapidly, efficiently; It can also suppress the generation of stink substances such as indoles, thiolate, skatole, thereby removes peculiar smell.. (2) solid dielectric is beneficial to microorganism and forms stable ecosystem, and the kind of perching microorganism is more, the processing efficiency height.By the multilayer active biological film, in the final stage of sewage disposal, use this product will help separating of mud and water, shorten dwell time of sewage, and effluent quality is cleaned more.. (3) nontoxicity is non-corrosiveness also, nonstaining property more, and its use is without any special requirement or avoid the scope of using.The degraded product sludge quantity is few. (4) convenient management, easy use.Directly be added in the water body and get final product, do not need additionally to increase facility, save energy has been saved the input of fund.
