Description
Technical field
The invention belongs to technical field of sewage, more particularly, are related to a kind of using A2/ O-MBBR reactor, can
Reverse washing flat membrane bioreactor and middle pressure can on-line cleaning ultra violet sterilizer sewage disposal system, especially suitable for rural area
Area uses.
Background technique
With the propulsion of Development of China's Urbanization, rural sewage treatment is the important component of new countryside construction.Life in the countryside
Sewage is one of face pollution source, and the sanitary sewage or excrement and urine water in 90% or more the whole nation are directly discharged to the stream such as underground or lake
Domain, as the eutrophication in Taihu Lake, Dian Chi has part from domestic sewage in rural areas.The random discharge of country sewage, dry pail latrine
It uses, the water environments such as rivers and lakes basin, underground water is caused to be contaminated.Country sewage is administered, life in the countryside can not only be improved
Environment, moreover it is possible to which the water pollution of control catchment and the eutrophication in lake improve water body environment, while the middle water handled is used for agriculture
Industry is irrigated, and the anxiety of agricultural water is alleviated.Therefore it is badly in need of the sewerage of research new rural village, proposes the diversified agriculture for being suitble to China
Village's sewage disposal system.
In current processing system, including anaerobic pond-anoxic pond-aerobic tank A2O processing system is to organic pollutant
High treating effect, especially biological phosphate-eliminating and denitrification effect are obvious, and anti impulsion load ability is strong, and operational management is fairly simple, can
To guarantee water outlet relative stability that sewage treatment plant runs under the conditions of various influent qualities.But it is dense for ammonia nitrogen in water inlet
High sewage is spent, A is only used2O processing system can not be met the requirements.
Membrane bioreactor MBR(Membrane Bio-Reator) it is membrane separation technique and the organic knot of biologic treating technique
The sewage disposal system of conjunction.The secondary settling tank for replacing traditional biological processing technique end with membrane component keeps high in biological respinse
Activated sludge concentration improves biological treatment organic loading, to reduce sewage treatment facility occupied area, and by keeping low dirt
Mud load reduces surplus sludge volume.Currently used is mostly immersion, and in order to improve filter area, what film mostly used is hollow fibre
Tie up film.But this reactor is easy blocking, especially in rural area, once blocking, equipment are at " getting sun " state,
It does not use, results in waste of resources from this, sewage does not handle and more causes environmental pollution.
Disinfection by ultraviolet light technique because its efficiently, do not generate disinfection by-products, be without secondary pollution to water body the features such as in recent years
It is developed rapidly, has obtained more and more applications.It is the good alternative techniques of the following liquid chlorine disinfection, mechanism is to utilize
The ultraviolet light of appropriate wavelength can destroy the DNA(DNA in microflora organisms cell) or RNA(ribonucleic acid)
Molecular structure causes growth cell death and (or) regenerative cell dead, achievees the effect that sterilizing.
Traditional middle pressure ultra violet sterilizer is relatively broad in water process germicidal applications, but due to the rating of set compared with
Height, so can generate a large amount of heat when sterilization, which increase quartz socket tube temperature, the place temperature closer from quartz socket tube
Degree is higher, and high temperature makes quartz socket tube calcium and magnesium particle fouling serious, the more mostly traditional ultraviolet sterilization device germicidal efficiency of fouling
It is lower, must not cause and irregularly shut down to ultraviolet sterilization device progress chemical cleaning, is safeguarded.Not only troublesome maintenance, and
Need manpower excessively high.It is even more not applicable for the vast rural areas.
Summary of the invention
The purpose of the present invention is overcoming the deficiencies of the prior art and provide the integrated system of suitable rural sewage treatment, allow more
More rural areas afford to build, with it is good, make positive contribution to build beautiful rural area.
