Embodiment
Below in conjunction with embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.
Sewage is first removed large floating matter through coarse rack in factory, then from flowing into water collecting basin.Sewage is promoted to Assembled rotary fine fack through vertical sump pump, and Assembled rotary fine fack can be separated foreign material and sand grains from waste water, can remove a part of organic loading simultaneously.Rotate fine fack process water outlet and be introduced into anaerobic pond, by thruster, anaerobic treatment is carried out in water inlet and anaerobic sludge mixing, then from flowing into biochemistry pool, adding our the effective microbe microbial inoculum of exploitation during first operation (is with photosynthetic bacteria group, lactobacillus, yeast flora, the 5 large classes 10 such as the thread flora of Gram positive actinomycetes group and fermentation belong to the composite fungus agent that more than 80 plant microorganism composition, thus powerful probiotic bacterium flora is formed, by oxidation, reduction, the approach such as fermentation, decompose oxidation of organic compounds, can degradation of organic substances effectively, suppress, kill various unwanted bacteria, suppress the propagation of prevailing disease pathogenic microorganism, the common peculiar smell such as removal of hydrogen sulfide and ammonia, play the effect of environmental protect), the oxygenation of suspensive chain type aerator aeration is utilized to carry out aerobic treatment, sewage after process, carry out aeration aerating after precipitation again to stablize, sewage self-flowing enters sterilization pool, discharge after sterilization.Sludge thickener sent into by the mud sludge pump that precipitation produces, and mud to be made a gift to someone belt filter press dehydration by spiral pump after concentrated again.The supernatant liquor that sludge thickener produces and the filtrate that pressure filter produces are from flowing into water collecting basin secondary treatment.The oxygen that aeration and clarifying process need is supplied by blower fan, the mechanical foreign material outward transport landfill stabilization that pre-treatment facility produces, and the excess sludge outward transport of generation is fertile as agriculture.
The process characteristic of this sewage water treatment method:
Invest low: owing to adopting Tu Chi to add seepage control measure, the construction cost of water per ton is greatly about about 800 ~ 1000 yuan, and the construction cost of AAOM technique water per ton is about 3000 ~ 3200 yuan.So expense is significantly less than the construction cost of other process spent water treatment plants needed for water treatment method in the present invention.Also there is floor space in addition little, arrange with suiting measures to local conditions, not by the influence of topography.
According to State Bureau of Environmental Protection 1992 " investigation and research of Industrial Wastewater Treatment facility ", China's Industrial Wastewater Treatment facility fund 54% for civil engineering facility, and only have 36% for equipment, cause the major cause of this Investment Allocation general layout to be that process pool mostly adopts expensive steel reinforced concrete pool.And imperial field Sewage Plant civil engineering cost, only account for 20% of gross investment.Large steel reinforced concrete pool is not only expensive, and difficulty of construction is large.In order to reduce investment, first the aeration tank adopted in the present invention is use HDPE anti seepage membrane to completely cut off sewage and underground water, is secondly that the micro porous aeration head be suspended in float tube avoids pool wall perforation installation at the bottom of pond.The Tu Chi of this HDPE of laying anti seepage membrane is not only easy to excavation, low investment, and treatment tank requirement functionally can be met completely, and can suit measures to local conditions, adapt to on-the-spot landform admirably, under depositing some special geologic condition, as earthquake prone areas, the soil is porous area, its advantage is embodied more fully.Lay native pond work-ing life of HDPE anti seepage membrane considerably beyond steel reinforced concrete pool.
Efficiency is high: utilize the floating aerating chain system of keeping afloat, micro porous aeration head is arranged at bottom, and aeration efficiency is high.Aerator is arranged on pool side, and energy consumption is little.Energy consumption is only about 1/2 ~ 1/3 of traditional wastewater process.
Traditional wastewater process seldom adopts underload Sludge System, this is because not efficient, and rational technique and aerator.The development of C-BIOLAK aerator (BIoLAK mono-FluoX), for we be familiar with already and the utilization obtaining this technique of certain effect opens more great scope of land.The power consumption in the system aeration tank of C-BIOLAK aerator needed for mixing effect is adopted to be only 1.5 watts/m 3, and in general traditional aeration method, the power consumption of mixing effect is 10 ~ 15 watts/m 3, this very valuable improvement beyond doubt.
Sludge reflux amount is large: in operational process, and the mud of 30 ~ 40%, by microbial consumption, separately has the sludge reflux process of 30 ~ 40%, excess sludge is 20 ~ 30% energy long storage time without putrefactions of traditional technology, do not produce stink, through storage pool mummification, can agricultural fertilizer be done.C-BIOLAK process sludge quantity of reflux is large, and sludge concentration is higher, and biomass is large, and relative aeration time is longer, so sludge loading is lower.
Technique is simple: this technique starts fast, operation, management, easy to maintenance, and after stable, the working cost of sewage per ton is lower, is about 1/3 ~ 1/4 of traditional method.Emptying or stopping production is not needed during maintenance.Due to the structure that C-BIOLAK micro-hole aerator (BloLAK mono-FluoX) is special, both aerator in very complex environment had been made also to be unlikely to block, this means that aerating apparatus can run several years and not keep in repair, decrease the workload of maintenance, so need maintenance cost little.C-BIOLAK technique is by a large amount of returned sluge, and its excess sludge reduces a lot than traditional technology.Before use mud, no longer need any process, therefore, the expense of flower on lignin-sludge is also very low.
C-BIOLAK system does not have fixing part under water, need not drain the water in pond, and mentioned by the aeration head under aerator chain to repair location with canoe during maintenance.Practice shows, aeration head runs several years and also need not anyly keep in repair, and this mainly because aeration tube is made by very thin fiber (diameter is about 0.003mm), and uses polymkeric substance filling, to reach the object of waterproof and anti-foul.Meanwhile, aeration head has the free space of about 80% and the surface of 20%, and traditional aeration head is just contrary.Therefore, the area that microorganism can grow is very little, and is easy to be removed.When aeration head must keep in repair, do not affect the operation in whole sewage farm yet.Moving-member and the easy ageing component of this technique are all little.When the equipment of selection and material, all have employed reliability and durability material.This technique is without the need to too many automatization.It is both without any need for the detector of rapid wear, also without any need for the Controlling System of complexity.
For improving sewage treatment capacity, add effective microbe microbial inoculum, each pollutant of can effectively degrading in operational process, removing stink, lowers pollution load.Microorganism can run under normal temperature, normal pressure, and not only energy consumption is low, outlet effect is good, and does not have secondary pollution.Effluent quality reaches the secondary water quality standard of GB8979-96, and process can consider reuse further.
The above; be only the present invention's preferably embodiment, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
