Description
Technical field
The present invention relates to the field of sewage disposal, more specifically relate to a kind of dispersion point source sewage disposal levitation device, be applicable to process contaminated middle-size and small-size pool or irrigation canals and ditches that rural area or small towns comparatively disperse.
Background technology
China starts more lately to the attention of rural sewage treatment, and main polluted water is to disperse point source sewage.Rural area disperses the principal feature of point source sewage: (1) country sewage is mainly sanitary sewage and take the mixture of the processing sewage that agricultural-food are raw material, be substantially free of heavy metal and hazardous and noxious substances, contain a certain amount of nitrogen and phosphorus, biodegradability is good, but water quality and quantity changes greatly; (2) Rural areas population is sparsely populated, and major part does not have network of drains, and sewage centralized collection intractability is larger; (3) sewage disposal also rests on small-sized focusing on, and can not meet the principal feature to country sewage---disperse the processing of point source.At present, the method for rural sewage treatment mainly contains following several: (1) natural system, and utilize soil as the media for the treatment of and disposal, comprise artificial swamp, stablize oxidation pond etc.Also have some sludge treating systems, as dry husky bed and lagoon.Natural system processing energy consumption is low, processing effluent quality is good, can play beauty function, cost of investment is low; The restriction that but floor space is large, processing effluent quality is unstable, be subject to land acquisition.(2) traditional biochemical treatment system, utilizes anaerobism, anoxic, aerobic process to dispose of sewage, good, the technical maturity of outlet effect after processing, but be applicable to large flow sewage disposal, floor space is large, working cost is relatively high, initial cost is high.(3) MBR treatment technology, a kind of by the new and effective wastewater treatment and reuse technique of membrane separation technique and the combination of traditional wastewater biological treatment.A large amount of microorganism (active sludge) fully contacts with labile organic compound in waste water etc. in MBR, by oxygenolysis, carries out metabolism to maintain self growth, breeding, simultaneously degradable organic pollutant; The then mechanical grading by ultrafiltration or microfiltration membrane, the effect such as hold back carried out solid-liquid separation to waste water and mud mixed liquid, thereby obtained the water outlet of clarification.Domestic for not systematize so abroad of distributing wastewater treatment research, more is the processing to community wastewater, and technique remains the miniaturization of the combination ，Shi municipal sewage plant of traditional method.Along with scientific and technical development, the especially development of MBR technology, sewage treatment facility has realized deviceization, miniaturization, and sewage dispersion treatment and reuse are achieved.MBR technology floor space is little, effluent quality good, can not produce secondary pollution, processing water outlet can direct reuse; But investment cost is high, operational requirement is high, working cost is high.
Summary of the invention
The object of the invention is to be the problems referred to above for prior art existence, a kind of dispersion point source sewage disposal levitation device is provided, this device can effectively disperse point source sewage process to rural area.Device is made simple, and with low cost, material is easy to get, environment protection health, stable, long perfomance life, treatment effect is good, convenient operation and management, whole treatment unit is placed under water, does not take floor area, does not affect water landscape, its size and submarine site can be adjusted according to actual needs flexibly, and use range is extensive.
In order to realize above-mentioned object, the present invention adopts following technical measures:
A dispersion point source sewage disposal levitation device, this device comprises 4-16 monomer structure, each monomer structure is managed pedestal by UPVC and is interconnected.It is characterized in that: each monomer structure is comprised of a year bacterium container, microbiobacterial agent, rubber fixed head, communicating aperture, UPVC pipe, outage, sponge column, soft biological matter carrier, bristle algae, the plastics string bag, UPVC channel closure plug.Rubber fixed head is set in one end of UPVC pipe and is fixed on the bottleneck that carries bacterium container, UPVC pipe is communicated with a year bacterium container by the communicating aperture in rubber fixed head, the other end of UPVC pipe seals by UPVC channel closure plug, on UPVC pipe, be arranged with soft biological matter carrier, UPVC pipe inside is filled with sponge column, on UPVC tube wall, offer outage, on soft biological matter carrier, be arranged with the plastics string bag.Carrying bacterium container is inverted cylindric plastic containers, the microbiobacterial agent of interior storage dilution.UPVC pipe one end is fixed on and is carried bacterium vessel port place by rubber fixed head, and the other end seals by UPVC channel closure plug, and the UPVC tube wall both sides 10-12cm of being often separated by offers outage, filling sponge post in UPVC pipe.In rubber fixed head, make a call to five little communicating apertures, to allow the microbiobacterial agent carrying in bacterium container enter in UPVC pipe.Soft biological matter carrier surface field planting bristle algae, with the plastics string bag with further fixing bristle algae.Sponge column plays the effect of slowly-releasing microbiobacterial agent, makes microbiobacterial agent slowly through the aperture on UPVC tube wall, flow out and then to be filled in soft biological matter carrier equably, to supplement the film component of degeneration.In order to be connected and fixed the UPVC pipe pedestal of monomer structure, it is a rectangle pipe frame being formed by the UPVC pipe of hollow.Between four UPVC pipes of pipe frame periphery, by L shaped plastic connector, connect, optionally can to increasing 1-3 root UPVC, manage in pipe frame central longitudinal, and make two adjacent longitudinal UPVC pipe interval 30-60cm.The UPVC channel closure plug of each monomer structure lower end is fixed on UPVC pedestal by T shape plastic connector.Adjacent two monomer structure upper ends are fixed with T shape plastic connector by UPVC fixed transverse rod apart from 5-10cm place, rubber fixed head lower end, further to increase its stability, and can be optionally unfixing yet.
Described soft biological matter carrier 4 adopts the vegetable fibre chalina of pure natural, need in use the mass ratio by 5%() NaOH solution soaking, it is carried out processing for 10-12 hour makes it softening, chalina after processing has the feature of soft porous, and microbiobacterial agent can form microbial film in its space.
The described microbiobacterial agent carrying in bacterium container is to buy the high concentration microorganism microbial inoculum of producing in Heyuan Green Biological Engineering Co., Ltd., Wuhan, this microbial inoculum is Powdered, and wherein flora is subtilis: streptococcus faecium: denitrifying bacterium=2: 2: 1; User can buy flora than the microbiobacterial agent of other identical company according to practical situation.
