Description
Technical field
The utility model relates to sewage treatment area, is specifically related to detest/facultative anaerobic biochemical of sewage and processes with water quality and quantity and regulate the balanced flow control device that goes out, and can control equilibrium and go out to flow, and is applicable to the pretreatment unit of town & country domestic sewage treatment process front end.
Background technology
Take sanitary sewage in main town & country sewage, mainly contain suspension class, colloidal type and dissolving type organic, belong to middle low-concentration organic wastewater, its biochemical is better, and the generally processing of sanitary sewage is all the method that adopts biological treatment.
Wherein, town domestic sewage is processed, and take for a long time aerobic treatment as main always, most activated sludge method processing techniques that adopt.But activated sludge process is built investment greatly, and energy consumption and working cost are high, and quite some urban wastewater treatment firms, can not give full play to its benefit because being difficult to bear working cost.Therefore, reducing energy consumption, minimizing working cost tool in town sewage processing is of great significance.
And the processing of domestic sewage in rural areas by using is mainly divided into 3 large classes at present: anaerobic-aerobic biochemical treatment, stabilization pond are processed and land treatment technique.General according to local Characters of Geographical Environment and social-economic development status, the sewage water treatment method of suiting measures to local conditions to select.
The sanitary sewage marsh gas purifying pond that adopts anaerobic biological to process, pre-treatment anaerobically fermenting is more abundant, and organic removal efficiency is also higher, and the biofiltration effect in the facultative filter tank of aftertreatment is also clearly.Its advantage is: not consumption of power, stable, simple and convenient management, excess sludge is few, working cost is low, can also reclaim the energy (biogas), can build under greening or vegetable plot, does not take up an area, and invests moderate; But also exist technically: dwell time of sewage is long, and treatment effect is unstable, and in water outlet, part index number is difficult to reach emission standard, to problems such as the removal effect of suspended substance, ammonia nitrogen and phosphorus are poor.And employing aerobic treatment, although reliable, treatment effect is good, also exists the problems such as construction investment is large, power consumption is many, working cost is high, excess sludge processing is difficult.
Stabilization pond process be a kind of utilize sewage in the pool through the stop of long period, storage, by the Metabolic activity of microorganism, and the physics accompanying, chemistry, physical and chemical process, make pollutent, nutritive substance and harmful and noxious substance in sewage be changed, degrade and remove.Can make full use of landform and save construction investment, treatment system does not consume energy substantially, but stabilization pond also exists shortcomings, and as organic loading is low, floor space is large, and the impact for the treatment of effect climate condition is large, and the algae of suspension makes the shortcomings such as water outlet COD is higher.
Land treatment technique be controlledly by sewage dosing to soil, utilize the effect such as physics, chemistry, physical chemistry, biological and ecological of soil-plant-microorganism composite system to realize the treatment technology of pollution degradation material.Land treatment technique, according to the difference of processing target and processing object, can be divided into the ecological treatment system of 5 types of slow rate, diafiltration fast, overland flow, subsurface infiltration and Wetland ecologicals etc.What wherein application was wider is rapid infiltration land and artificial swamp ecological treatment system.
These two kinds of sewage disposal technologies of rapid infiltration land and artificial swamp, although have the lot of advantages such as treatment facility less investment, treatment effect is good, working cost is low, also exist some shortcomings such as hydraulic load is low, floor space large, easy obstruction.Its hydraulic load is low has caused the less than normal of system processing power, if will improve processing power, necessary expansion system floor space, need to take a large amount of soils, thereby seriously limit this system applying in dense population areas; Next is higher into water requirement, must strengthening pre-treatment measure remove large granular impurity and suspended solid in sewage, improve influent quality, make to remove at pretreatment stage into the suspended solid in water, prevent and avoid the obstruction of filtration system, filter material for artificial wetland; It three is the abundant oxygen supplys that will solve in soil and water, and the problems such as impact of being bullied gentle vegetation season.Therefore also need its treatment system technique to carry out Improvement and perfection optimization.
Secondly, sewage in samll cities and towns and rural area generation, erratic behavior due to its sewage discharge, water quality and quantity changes fluctuation greatly, in addition the difference of different areas socio-economic development situation, sewage disposal is subject to the constraint of the level of economic development, so a kind for the treatment of effect of How to choose is good, construction investment is few, working cost is low, the treatment technology of convenient management, is the key that solves current samll cities and towns and rural domestic sewage treatment problem.
Make a general survey of above several treatment process, above-mentioned several living sewage purifying treatment appts,, also there are many problems simultaneously in existing advantage separately.Therefore research and develop that treatment effect is good, construction investment is few, less energy-consumption, sewage treatment process efficiently, be current samll cities and towns and rural sewage treatment technical field problem demanding prompt solution.
For current samll cities and towns and rural domestic sewage treatment, form anaerobic fermentation methane treating pond, rapid infiltration land and these several technology of artificial ecology wet land sewage treating process, advantage is obvious, and technology is comparative maturity also.Purifying methane tank, pre-treatment anaerobically fermenting is more abundant, and organic removal efficiency is higher, and the biofiltration effect in the facultative filter tank of aftertreatment is also clearly; Its subject matter is weaker to the removal effect of suspended substance, ammonia nitrogen and phosphorus.And the defect of rapid infiltration land and artificial swamp be into water, require higher, must there is pre-treatment first to remove large granular impurity in sanitary sewage, avoid causing the obstruction of rapid infiltration land bed, filter material for artificial wetland, and the effect of rapid infiltration land bed, artificial swamp removal ammonia nitrogen and phosphorus is very good.Therefore these several technology are organically combined, just can learn from other's strong points to offset one's weaknesses, aspect processing samll cities and towns and domestic sewage in rural areas by using, obtaining extraordinary treatment effect.
Anaerobic biological sewage disposal technology is metabolism and the characteristic of utilizing anaerobion, without providing under the condition of external source energy, using the organism that is reduced as hydrogen acceptor, in degradation of organic substances, produce the energy---the biogas there is utility value, thus it be current economy, effectively, one of the solution organic sewage of the low consumption important channel of processing.Along with the development of anaerobic biological technology, people apply anaerobic biological technology in town sewage is processed, sewage treatment process efficient to obtaining, low consumption.And for the sewage containing suspension class, colloidal type and dissolving type organic, through anaerobic hydrolysis-acidification process, organic pollutant can be degraded to a certain extent and be improved its biodegradability.Because in whole Hydrolysis Acidification, under the effect of the oxygen bacterium of detesting, hold concurrently, non-dissolved organic matter in sewage is held back and progressively changed into dissolved organic matter, wherein more than 80% water inlet suspended substance hydrolyzable becomes soluble substance, larger molecular organics is degraded to small molecules, be not only the macromolecular substance of difficult degradation and degraded, and water outlet BOD
5/ COD ratio improves, and has reduced oxygen requirement and the aeration time of follow-up aerobic treatment.
And in sewage aerobic biochemical treatment process, because aerobic biochemical reaction is comparatively responsive to water quality and quantity impact load, in order to make waterpower pipe duct and sewage treatment unit, normally work, be not subject to the impact of sewage peak flow or change in concentration, before sewage disposal main process facility, often need to arrange the equalizing tank of appropriate size and volume, water quality and quantity is carried out to equilibrium and regulate, to guarantee the steady running of aerobic biochemical reaction.
Therefore, in existing sewage treatment process, employing arranges equalizing tank the sewage quality water yield is regulated, or adopt and anaerobism (acidication) biochemical (the lower anaerobic biological that is called for short) pond to be set dirty organic pollutants is carried out to anaerobic biological degraded, become the pretreated necessary technological measure of sewage.But in sewage treatment process, be all that water quality and quantity equalizing tank is set respectively individually conventionally, or anaerobic biological pond, cause separately the equalizing tank arranging separately, the function ratio in anaerobic biological pond is more single, cause the volume space size of sewage pre-treatment facility structures to increase, increased and taken up an area and investment, made the employing in anaerobic biological pond be subject to certain restriction.
In sewage treatment process, extensively adopt at present, the equalizing tank regulating for the sewage quality water yield, can not be when realizing water quality and quantity adjusting, synchronously carry out good anaerobic biochemical reaction, realizes water quality and quantity and regulate the reason merging with anaerobic biological technique, and the major defect existing there is the following aspects:
The one, as the equalizing tank of the balanced sewage quality water yield, common situation is under certain water level discrepancy in elevation condition, water inlet is with unbalanced flow, gravity flow enters the relatively low equalizing tank of water level elevation, the ununiformity that enters equalizing tank due to sewage, therefore at equalizing tank, carry out in the process of water yield adjusting, few when many when entering sewage quantity in equalizing tank and being, water level is also that the number with sewage quantity changes, state in frequent change, can not guarantee and meet at all sewage and carry out anaerobic biological requirement, must guarantee certain water level and the processing condition in reaction times, especially when equalizing tank median water level is during in low-water level, the hydraulic detention time of its anaerobic biological is too short, cannot guarantee the basic anaerobic biochemical reaction time at all, is therefore difficult to realize the effect of anaerobic hydrolysis-acidification.As guaranteed basic anaerobic hydrolysis-acidification reaction hydraulic detention time, must adopt buried depth more deeply and the equalizing tank structures of larger water yield storage volume space, this will greatly increase undoubtedly equalizing tank and build cost of investment.
The 2nd, the equalizing tank regulating as the sewage quality water yield, common situation is preposition equalizing tank, because equalizing tank is preposition, often because sewage water inlet water level is lower, equalizing tank upper volume can not be filled storage sewage, causes the vacant loss of equalizing tank upper volume of considerable part.
The 3rd, if equalizing tank is set behind anaerobic biological pond, sewage must promote to enter through lift pump and in anaerobic biological pond, carry out anaerobic biochemical reaction, then enter equalizing tank and carry out the adjusting of the sewage quality water yield, but unbalanced due to amount of inlet water, in order to keep equalizing tank to go out the equilibrium of streamflow, must with lift pump, carry out second lift again, in order to regulate, control the constant streamflow that goes out, meet the requirement of the balanced water inlet in follow-up sewage treatment process unit and hydraulic load, this has increased the lifting power consumption of disposing of sewage undoubtedly, is very uneconomic.
Therefore make full use of sewage quality water yield equalizing tank and there is larger water yield storage volume space, feature with certain hydraulic detention time, research and develop the equilibrium adjusting that can either carry out the sewage quality water yield, can carry out anaerobic biological degradation of sewage organic pollutant again, the water quality and quantity of collection sewage regulates, with organic pollutant anaerobic biological degradation function one, new and effective, low consumption, the multiduty sewage quality water yield regulate with anaerobic biological and process integrated apparatus, and in sewage pre-treatment, tool is of great significance.
