Description
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.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide one and can be effectively improved sewage biochemical reaction efficiency and sink
The effect of shallow lake water outlet, effluent quality good villages and small towns waste water treating and reutilizing device and technique.
For achieving the above object, the technical solution used in the present invention is: a kind of efficiently villages and small towns waste water treating and reutilizing device bag
Include apparatus main body and remote environment medicine expert diagnosis control system；Remote environment medicine expert diagnosis control system realizes device
Operational management unmanned, intelligent.Apparatus main body has inner chamber, and described inner chamber includes module between integration of equipments, biochemical reaction
Module, three big modules of mud-water separation module, the big module of described three is the integral type of integral type or Split assembled；Described biochemistry
Reaction module separated by dividing plate and be provided be sequentially connected pre-deoxidation mud membrane cisterna, release phosphorus mud membrane cisterna, denitrification phosphorus-collecting mud membrane cisterna, good
Oxygen mud membrane cisterna, described mud-water separation module is divided into preformed precipitate district, essence settling zone, uses clinodiagonal Inlet and outlet water between adjacent cell body
Mode, clinodiagonal Inlet and outlet water can increase and prolong the journey distance response time, optimizes flow-shape and then improve treatment effect, adjacent
Use partition wall water hole or downflow weir to cross water, water hole and mill weir excessively between cell body and be provided with separation net when being filled with floating stuffing,
Sedimentation tank outlet conduit is connected with the ultraviolet sterilizer in module between integration of equipments；Mud in described preformed precipitate district, essence settling zone
