Description
Technical field
The utility model belongs to technical field of waste water processing, particularly a kind of Small Sewage Treatment Equipment.
Background technology
China just should use for reference the experience of advanced country now, at Development of Urban water drain network with while increasing sewage work, also want the small-sized fixed purifying domestic sewage groove that active development is new, solve water drain process sanitary sewage can not be laid in the low samll cities and towns of the density of population and mountain area problem because of cost intensive.There are the research and development of the small-sized fixed purifying domestic sewage groove technology of independent intellectual property right; not only greatly can promote the development that China disperses regional sewage treatment industry; improve the level of competitiveness of Environmental Protection in China equipment research; also because the popularization of small-sized purification tank has the feature of waste water control " every household property of participation ", also there is very high strategic importance to the raising of the national environmental protection consciousness of China.
The energy consumption cost of sewage work generally accounts for about 30% in the cost of business operation of sewage disposal.Data display according to the relevent statistics, wastewater treatment in China factory and office reason lm
3the current consumption of sewage is generally 0.14 ~ 0.28kwh, if comprise sludge treatment, and lm
3the current consumption of sewage is 0.19 ~ 0.36kwh, far away higher than the U.S., Japan and other countries, has larger energy-saving potential.Wherein aerator power consumption accounts for 40% ~ 50% of total energy consumption, and be use energy first rich and influential family of Sewage Plant, the power consumption of sewage, sludge lifting pump can reach 10% ~ 20%.Middle or small sewage treatment time of generally founding the factory is longer, and technique is backwardness relatively, and energy consumption level is higher.But middle-size and small-size sewage disposal device has, and cost is low, investment instant effect, safeguard the advantages such as simple, applying flexible, if can reduce the energy consumption of aerator and lift pump, middle-size and small-size Sewage Plant can reach the object reduced costs.The difficult point popularized of purification tank is its cost issues with emphasis with the universal the same of other environmental facilities, install and use the expense that purification tank expense comprises equipment and materials in the one-time investment process of construction of purification tank, and in the management of purification tank run duration and equipment working cost.
The living habit of resident and daily schedule are different because of area, season and national customs, the service condition of family life facility and local economic conditions, Living consumption, age structure and the consumer group etc. are closely related, and the impact by external environment (as local nature and ecological conditions such as temperature, precipitation, wind direction and soil) in actually operating and concrete practice is very large.These factors affect the normal operation of the sanitary sewage dispersion selecting properly for the treatment of process, treatment process and the appropriate design of pollutant removal scheme, the accurate estimation of effluent quality and sewage treatment facility above.Therefore family domestic sewage to be made directly to process up to standard, will shock resistance be realized technically, the particle suspensions being difficult to degrade also will be suppressed to enter into follow-up phase, guarantee that high-concentration sewage does not enter low concentration region.
