Description
Technical field
Invention is related to field of environment protection, and in particular to a kind of deep bed multiplication MBBR reactors of rural sewage treatment.
Background technology
In the evolutions such as village industry, aquaculture, production, sanitary wastewater discharge and fixed waste increase, and drink
Water scarcity management, a large amount of uses of chemical fertilizer, pesticide, the random discharge of feces of livestock and poultry, township enterprise's pollutant, to rural area water body
Environment causes huge pollution.
The research of China's rural domestic sewage treatment is started late, and technology category is various.Country sewage has dispersibility, water
Amount differs greatly, the relatively low multiple features of pollutant concentration, and the centralized processing of most area domestic sewage in rural areas is faced and built
If quantities is big, the high problems of investment, even if building up centralized wastewater treatment facility individually, but still problem is deposited,
Sewage disposal technology is unfamiliar in area management, causes some wastings of resources.Main technique includes：Anaerobism+drowned flow artificial is wet
Ground/oxidation pond, buried type integrated land treatment systems, A2/ O and A/O techniques, MBR techniques etc..Wherein anaerobism+artificial wetland process
Technology maturation, investment cost is low, and operation and maintenance are simple, has the advantages that sewage disposal takes into account with beautification of landscape, is current south
The main technique of area countryside sanitary sewage disposal, the cost of investment height of existing sewage disposal, operation maintenance management trouble.
Therefore, exploration is low with development investment and operating cost, operation maintenance management is convenient, is suitble to each department actual conditions
Technology for treating domestic sewage in rural area and governance model be particularly important.
Invention content
Goal of the invention is to provide a kind of deep bed multiplication MBBR reactors of rural sewage treatment, solve at existing sewage
The problem that the cost of investment of reason is high, operation maintenance management bothers.Therefore the present invention designs a kind of deep bed of rural sewage treatment
Double MBBR reactors, reduces the operating cost of sewage disposal, and sewage disposal is combined with the planting environment in rural area,
Improve land utilization ratio.
The present invention is the anaerobic-anoxic-MBBR- Tiny ecosystem filter bed treatment process for rural sewage treatment, and sewage is through weight
Force flow mentions anaerobic pond by simple grid, into regulating reservoir pump, and acidification is hydrolyzed in organic matter, returned sludge releases phosphorus；Nitrification
Enter anoxic pond after liquid reflux mixing and carry out nitration reaction, the LEVAPOR fillers of 15-20% is added in the ponds MBBR, and to it
Stirring, oxygenation aeration, filler interception etc., carry out nitration reaction and poly- phosphorus；Water outlet enters vertical-flow secondary settling tank mud-water separation, and two is heavy
Pond water outlet gravity flows to Tiny ecosystem filter bed, and under matrix effect, plant action, microbial action, water outlet, which can stablize, to be reached《Cities and towns are dirty
Water sewage plant pollutant emission standard》(GB18918-2002) level-one A is marked.
Invention is achieved through the following technical solutions：
A kind of deep bed multiplication MBBR reactors of rural sewage treatment, including sequentially connected anaerobic pond, anoxic pond, MBBR
