Description

A kind of efficiently villages and small towns waste water treating and reutilizing device and technique thereof
Technical field
The invention belongs to sewage treatment area, be specifically related to a kind of efficiently villages and small towns waste water treating and reutilizing device and technique thereof.
Background technology
At present, China's water environment and ecological environmental pollution problem become increasingly conspicuous, the sanitary sewage on the ground such as overwhelming majority rural area The most untreated with regard to the most directly discharge, and great majority are directly discharged into natural water, and surrounding body and soil are caused severe contamination.So And, the features such as China's domestic sewage in rural areas has distribution dispersion, with a varied topography, pipe network covering imperfection, and the water yield is unstable, uncomfortable Close and use large centralised sewage treatment plant to process.Existing integrated sewage treating apparatus mainly include activated sludge process, Biomembrance process and membrane biological process device.First, existing activated sludge tank result in the size of this device owing to treatment effeciency is relatively low Big and high cost feature;Secondly, existing biomembrance process (biological contact oxidation pond and BAF etc.) then exists general Store-through updates biomembrane difficult, aging at regular backwash, biomembrane and is difficult to come off and the problem such as difficult management;Again, existing Generally there is generation concentrated solution in membrane biological process reactor (MBR reactor etc.), energy consumption is high and operational management difficulty (manages and requires height Be not suitable for rural area promote) etc. problem;Finally, existing integrated apparatus dephosphorization process mostly uses chemical dephosphorization technique, not only Dischargeable capacity in pond can be occupied, and equipment manufacturing cost cost and management problems can be increased.Integrated sewage treatment recycling device and Generally there is the problems such as effluent quality is the most up to standard, floor space is big, energy consumption is high in its technique, it is to the nutrient removal rate such as nitrogen, phosphorus Relatively low.Therefore, mud membrane biological process, as a kind of novel sewage treatment process, has compact conformation and nitrification, de-carbon, denitrogenation effect The best, mud membrane bioreactor takes into account the two-fold advantage of biomembrance process and activated sludge process, effective in mud membrane bioreactor Microorganism concn includes suspension mud and biomembrane two parts, has effective Biomass high, and it is dirty that its Biomass is not only activity Bricklayer's's skill and the several times of biomembrane process, and can effectively overcome the shortcoming of conventional membrane bioreactor, have volumetric loading high, The features such as resistance to impact is strong.
Current existing integrated apparatus there is problems: 1, existing air stripping sludge recirculation system is that impulse type goes out Water, it is high and be difficult to control to the stripping reflux mud extraction water yield that dissolved oxygen is carried in water outlet, the most unfavorable to anaerobic reaction and be difficult to precisely control System;2, existing equipment water distribution is uneven and dead water region, short flow problem is serious and technique arranges unreasonable, is unfavorable for realizing efficiently The purpose of denitrogenation dephosphorizing;3, the anaerobic pond of existing equipment, anoxic pond base sludge deposit more, and mud fluidisation difficulty is difficult to High-efficient denitrification and dephosphorization reacts;4, existing integrated sewage treating apparatus sedimentation tank because of equipment unreasonable and floating without controlling to float Mud and go out the technical measures that aqueous suspension exceeds standard, causes sedimentation tank outlet effect poor;5, existing integrated apparatus can not be for water The change of the environment such as matter, the water yield, temperature is made corresponding operating condition and is adjusted, and operational management unmanned, intelligent exists more asking Topic.
In order to prevent the aggravation of body eutrophication, the pollutant such as water outlet total nitrogen and total phosphorus concentration need to maintain relatively low model In enclosing, it is achieved the integrated high-efficiency management of villages and small towns sewage-treatment plant, hence it is imperative that a kind of easily operation, one-tenth effective, low This treatment technology and equipment.
