Description
[technical field]
The utility model relates to a kind of sewage treatment unit, especially relates to a kind of dispersant type domestic wastewater integrated treatment unit.
[background technology]
According to Ministry of Construction's report of survey demonstration in October, 2005, China rural area has the sanitary sewage that surpasses 2,500 ten thousand tons directly to discharge every year, causes river, pool to pollute, and has influenced the rural residence environment.Rural Water Environment becomes the significant problem that concerns China's sustainable economic development, particularly in the location, water source, the south water to north is along the line and the reservoir area of Three Gorges, is concerning Urban Water Environment, quality and water security.All these improvement to domestic sewage in rural areas by using has proposed very high requirement.
Domestic sewage in rural areas by using collection difficulty is big, focuses on difficulty, so can only take the distributing tupe.The processing of rural area decentralized type sewage and reuse should be suited measures to local conditions, according to population size, peasant household's Distribution Pattern, village landform make overall planning, appropriate design.In addition, various places relevant departments should set up the inspection of specialty to safeguard troop after building up treatment facility, and sewage treatment facility is made regular check on.Sewage disposal for the Rural areas, have only according to practical situation and carry out Scheme Choice demonstration, working drawing optimization design, well-organized construction, conscientious maintenance management, just can make domestic sewage in rural areas by using obtain reasonable, effective, economic processing and reuse, really improve the water environment situation in rural area, accelerate the process of building a New Socialist Countryside.
The characteristics of domestic sewage in rural areas by using are: the sewage composition is simpler, and COD concentration is lower, and TN, TP concentration are higher, belong to middle low concentration sewage; People in the countryside are less relatively, and water supply standard is also lower; Lack maintenance management technician and operational management experience.The domestic sewage in rural areas by using technology of present exploitation, or directly adopt the town domestic sewage conventional process to be transformed, as utilize SBR, oxidation ditch, AB method or artificial swamp method.These methods are not considered the country sewage practical situation,
Chinese patent CN101591063A adopts the ICEAS biochemical process to handle country sewage, and this technology exists equipment complexity, the loaded down with trivial details deficiency of manual operation, reckons without the rural area and lacks maintenance management technician and the empirical practical situation of operational management.If all adopt control automatically, certainly will be difficult to bear because of the too high village economic condition that causes of equipment manufacturing cost.Chinese patent 200720173930.2 adopts " precipitation+underground vertical-flow wetland bed " combination process to handle domestic sewage in rural areas by using, and exist winter temperature to cross handling water temperature when hanging down is 7 ℃, the problem that causes processing efficiency to descend; There is the little defective of dephosphorization contribution in wetland, and this process using dephosphorization matrix adsorption and dephosphorization exists working time long slightly matrix to adsorb oversaturated phenomenon.Chinese patent CN101362624A adopts " anoxic+anaerobism+biological tank+settling tank+dephosphorization/secondary denitrogenation " art breading dispersion type domestic wastewater, though adopt the integration apparatus technology, compact construction exists technology too complicated, the deficiency that technology chain is oversize.
Contact oxidation method is a kind of of biomembrance process.Biomembrance process is meant microorganic adhesion on structures biofilm medium, and grows thereon and breed, by in the cell outside the born of the same parents of outer stretching, extension polymer make microorganism cells form fibrous tangled structure, biomembrance process claims fixedly embrane method again.It is a class waste water aerobic biologic treating technique arranged side by side with activated sludge process; Be artificialization and the reinforcement of soil self-purification process; The same with activated sludge process, biomembrance process is mainly removed the organic pollutant of deliquescent and colloidal in the waste water, simultaneously the ammonia nitrogen in the waste water is also had certain nitrated ability.
Biological contact oxidation process claims the submerged biological filter again, and filler is set in reactor, carries out aeration simultaneously in the pond, and the waste water of process oxygenation contacts with covering with biomembranous filler, and under biomembranous effect, arriving of waste water purifies.Exist characteristic as follows: highly-hydrophilic exists and adheres to water layer; The microorganism highly dense: various bacteriums and microfauna, these microorganisms play a part the organic pollutant in the main removal waste water, the food chain of---bacterium---protozoon (metazoan) that formed organic pollutant.
Microbe species variation: quiet relatively stable environment; SRT is longer relatively; Thread fungus also can raised growth, no sludge bulking problem; The frequency that microfauna such as threadworms, rotifers occurs is higher; Algae even insects also can occur; Biology on the microbial film: type is extensive, kind is various, food chain length and complexity.The food chain of microorganism is longer on the microbial film: holozoic nutrition person proportion is bigger, and the survival rate of microfauna is higher; The food chain length; Sludge yield is less than Sludge System (only being about 1/4).Can survive and help the carrying out of nitrification generation time than long microorganism.Sludge quantity is big, and active good (as be converted to MLSS, can reach 13g/L) have the microbial film characteristic, and returned sluge sludge bulking can not take place.
