Description
Technical field
The utility model relates to the special treatment device at contaminated water source, and referring in particular to the micropollutant water is the reuse water factory and office reason device at water source.
Background technology
China is the country of a water resources shortage, and water resources ownership per capita is merely 1/4 of world standard.From present situation, pollution of waterhead is serious day by day, and contaminated water source scope enlarges day by day.In recent years, though many work have been done by China aspect water prevention and cure of pollution, also newly built many sewage works, still in variation gradually, the pollution in waters, industrial developed regions is particularly serious for the water quality of many rivers and lakes.In this case, along with the quick growth of population and developing rapidly of industrial and agricultural production, it is impossible wanting to make the water quality that receives polluted source to recover in a short time.Under the original just very short situation of China's Freshwater resources, it is unpractical not using the Freshwater resources that polluted fully.That is to say that China waterworks and industrial water factory have to be faced with the undesirable contaminated water source of the more water quality of use as the water source of giving birth to back tap water and other purposes.In order to change this situation, the water source can only be warded off in addition at the upper reaches away from the city in some cities of China, builds new water factory, solves with the way of laying Long-distance Pipeline for Water Conveyance.This certainly will need substantial contribution and drop into a large amount of manpower and materials and carry out engineering construction and could realize.Moreover, in the long run,, newly ward off the water source and new pollution might occur again if fundamentally do not solve industry, agricultural and the domestic pollution problem that is on the rise.For this reason, in the face of China's national situation, develop the water technology at contaminated water source; Change traditional water treatment technology; Producing and ever-increasing material of people and culture life needs to satisfy, adapt to China's economy and social development, is that pendulum is in our problem anxious to be solved in front.
At present, the water source ubiquity problems such as dissolved organic matter increases, ammonia nitrogen is higher, water body has peculiar smell, colourity increases, algae reproduction, and we are polluted these, but is called little source of pollution water through still spendable source water after the special process processing.It is the subject matter of present stage China's water pollution that organism and ammonia nitrogen exceed standard; With the surface water body be waterworks and the industrial water factory at water source adopt mostly conventional water-purifying process such as coagulation, deposition, filtration, sterilization make a return journey in dewatering suspended substance and kill pathogenic agent, but conventional water-purifying process is difficult to remove the organic pollutant that increases day by day in the water.The domestic and international at present development research to contaminated water source treatment technology mainly contains physics, two aspects of chemistry, wherein mainly contains: use Powdered Activated Carbon mix suspending adsorption technology, to remove colourity and stink; Using ozone-biological activated carbon technology is to remove micro-content organism and decolouring and deodorizing; Various oxidation style (like potassium permanganate oxidation method, photochemical excitation oxidation style and catalytic oxidation) are removed little pollution technology.But are there is defective in these technology and problem such as costs an arm and a leg in various degree all.
Present conventional unit for treating water has a variety of, and for example a kind of conventional unit for treating water is connected to form by settling pit, preliminary sedimentation tank, ripple plate reactor drum, tube settler, rapid filter, sterilization pool and clean water basin.
More to the device of drinking water treatment both at home and abroad, mainly contain: utility model 93242813 belongs to the associated plant of water purification or WWT.Inner hybrid reaction district, settling region and the filtrating area of from the water inlet pipe to the rising pipe, being divided into successively of this device.Since reaction zone be provided with first reaction chamber that constitutes by speaking trumpet and awl tube and constitute by waved plate, work second reaction chamber that improves settling region water distribution current stabilization effect; In the settling region, be provided with inclined tube, in filtrating area, be provided with filter head plate associated plant and simple substance homogeneous filtering material.
Utility model 97246127 discloses a kind of integrated water treatment equipment; It has been coupled sewage works such as aeration air supporting settling pit, biological contact oxidation chamber on the basis of a plurality of unit of conventional water factory structures unit structures have improved the water conditioning ability.The rotation that it utilizes water to produce from tangential direction turnover eddy flow flocculation reaction chamber is flowed and is effectively improved flocculating conditions, the generation of favourable alumen ustum.Have notch on its annular water distribution pipe, the annular header, it is blocked to make pipeline be difficult for.Each unit structures is arranged rationally, compactly in this integrated water treatment equipment, has significantly reduced the floor space of whole device.
Number of patent application 200810050403 relates to a kind of micro-polluted drinking water New Process for Treatment, belongs to resource and environment field water pollution control technology.This utility model increased slow aeration and biological fluidized bed processing unit newly developed before traditional handling technology of water supply settling tank, simultaneously traditional aeration tank is divided into a plurality of infinitesimals through dividing plate, wherein dosed biological activated carbon; Formation fluidized-bed under the air-flow effect; Utilize the adsorption of gac and the effect of biofilm carrier can effectively remove organic contamination in the water, gac brings in constant renewal in the surface because of ciculation fluidized in reactor drum simultaneously; Can life-time service, working cost is low.The claim 1 of this utility model; A kind of little sewage drinking water treatment novel process; It is characterized in that, between traditional handling technology of water supply settling tank, increase slow aeration and biological fluidized bed processing unit newly developed, simultaneously traditional aeration tank is divided into a plurality of infinitesimals through dividing plate; Wherein dose biological activated carbon, formation fluidized-bed under the air-flow effect.
The each have their own advantage of device that is used for drinking water treatment at present, but the part that also comes with some shortcomings are difficult to remove the organic pollutant that increases day by day in the water etc. like conventional purifier.Therefore, must improve present water treatment device, make that organism can effectively be removed in the contaminated water, guarantee the quality of tap water.
The utility model content
To above-mentioned deficiency of the prior art; The utility model improves on technological now basis; What a kind of Biological Pretreatment unit+conventional water purification unit+advanced treatment film unit processing was provided is the reuse water factory and office reason device at water source with the micropollutant water; Effectively remove the organism in the sewage, guarantee the quality of water.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is:
A kind of is the reuse water factory and office reason device at water source with the micropollutant water, comprises conventional unit for treating water, sets up the Biological Pretreatment unit in the fore portion of conventional unit for treating water, and sets up the advanced treatment film unit in the rear section of conventional unit for treating water; Said Biological Pretreatment unit is connected to form by anaerobic pond, anaerobic hydrolysis acidulated pool, biological contact oxidation pond successively; Said advanced treatment film unit is a membrane bioreactor;
