Description
Technical field
The utility model belongs to sewage treatment area, is specifically related to a kind of small region sewage treatment system.
Background technology
Wastewater treatment in China industry development progress is more late, and before arriving reform and opening-up since the establishment of the nation, the demand of wastewater treatment in China mainly uses based on industry and national defence tip.After reform and opening-up, the fast development of national economy, significantly improving of living standards of the people, has pulled the demand of sewage disposal.After entering nineteen nineties, the wastewater treatment in China industry entry fast-developing phase, the speedup of sewage disposal demand is far above global level.
Since nineteen ninety, global sewage disposal Apparent con-sumption with average annual 6% speed increment, and the nineties is during the decade, and wastewater treatment in China Apparent con-sumption average growth rate per annum reaches 17.73%, is 2.9 times of world's average growth rate per annum.Enter 21st century, wastewater treatment in China industry grows at top speed.2000-2004, wastewater treatment in China consumption rose to 4,470,000 tons from 1,880,000 tons, and add 2.3 times, annual average rate of increase is more than 27%.Wherein, calendar year 2001, wastewater treatment in China Apparent con-sumption reaches 2,250,000 tons, and exceeding the U.S. becomes the first in the world sewage disposal consumption big country.Meanwhile, sewage disposal import also increases considerably.1998, wastewater treatment in China import 1,000,000 tons, became sewage disposal importer maximum in the world thus.2004 with ratio in 1998, sewage disposal import increasing degree reaches 27.14% every year.Estimate 2005, Chinese sewage disposal Apparent con-sumption will reach 5,000,000 tons, and import will remain on about 3,000,000 tons.
Along with the fast development of market of sewage treatment, wastewater treatment in China output also finishes the situation of hovering for a long time, achieves rapid growth.Wastewater treatment in China output rises to 2,360,000 tons in 2004 from 2000 460,000 tons, annual average rate of increase 82.6%, the proportion accounting for domestic market demand also by 2000 24.47% bring up to 2004 52.80%.And the same period, world's sewage disposal output then only with about 6% speed increment.
From the nineties later stage, China is state-owned to pass through to introduce and technological transformation with joint venture, and successively built up a series of sewage disposal production line, sewage treatment technology equipment is reached advanced world standards, and sewage disposal is produced and begun to take shape.Sewage disposal breed structure also there occurs positive change, and sewage treatment product quality improves rapidly.Particularly domestic sewage disposal cold-reduced sheet rapid development, 2003, domestic cold-reduced sheet output reached 1,700,000 tons, and exceed import volume first, the degree of self-sufficiency reaches 66%; 2004, domestic cold-reduced sheet output reached 2,000,000 tons, and the degree of self-sufficiency reaches more than 70%.From the end of the year 2004 to the end of the year 2005, domestic cold rolling sewage disposal production capacity, by increase about 1,500,000 tons, will meet domestic market demand substantially.By 2007, China will become the net exporter of sewage disposal.
In general, wastewater treatment in China is experiencing by small scale, level is low, kind is single, seriously can not satisfy the demands and have considerable scale and level, variety and quality significantly improve and tentatively meet the deep transformation of national economic development requirement, and sewage disposal demand progressively will realize self-sufficiency.
Residential quarters sewage comprises the waste water produced in daily life, comprises lavatory fecaluria, laundry bath water, kitchen etc.Containing large amount of organic in sanitary sewage, as Mierocrystalline cellulose, starch, carbohydrate and fat protein etc.; Also often containing pathogenic bacteria, virus and parasitic ovum people should water conservations, sewage is processed.Along with the raising of people's living standard, sanitary sewage discharge is more and more serious.
Due to the dispersion of dwell point, China community, source of sewage distributed points volume is few, and the scale of cities and towns level Sewage Plant is many lower than 10000 ton per days.The sewage treatment process that current domestic large-and-medium size cities sewage work often adopts has traditional activated sludge process, A2/O, SBR, oxidation ditch etc., if can cause due to high working cost with these technology building Small Town Wastewater treatment plants, cannot normally run.Must adopt reduced investment for the feature of samll cities and towns, working cost is low, reliably consistent, operates simple technique relative to management.
Utility model content
The utility model object is to provide a kind of reduced investment, and working cost is low, reliably consistent, operates the small region sewage treatment system of simple technique relative to management.
The technical solution of the utility model is: a kind of small region sewage treatment system, it is characterized in that, comprise the filtering basin connected successively, aeration tank, settling tank and water reservoir, filter screen is provided with in described filtering basin, sewage is by entering aeration tank after filter screen, aeration tank is circular pond, center, aeration tank is anaerobic zone, surrounding is aerobic zone, in anaerobic zone and aerobic zone, biologic packing material is set, bottom aeration tank, aeration tube is set, the sewage of filtering basin flows through anaerobic zone from top to bottom, then settling tank is entered after flowing through aerobic zone from the bottom up, the supernatant liquor of settling tank is connected into water reservoir again.
Further, described filter screen is arranged on filtering basin stage casing, and the water inlet pipe of filtering basin enters from filter screen lower end, and the rising pipe of filtering basin flows out from filter screen upper end.
Further, be provided with dividing plate in described settling tank, settling tank upper part is divided into Liang Ge district, the sewage through aeration tank enters from a district, flows out from another district.
The operation logic of native system is: first sanitary sewage enters filtering basin, large-scale floating matter is filtered by the mistake of filter screen, then from the top down by the anaerobic zone of aeration tank, then aerobic zone is passed through from bottom to top, water after process flows into settling tank and precipitates, supernatant liquor flows into water reservoir as subdistrict greening, landscape water, and superfluous water is from retention reservoir discharge.
