Description
Technical field
The invention belongs to and utilize materialization and biotechnology in the environmental engineering method to handle the integrated technology of courtyard domestic sewage, particularly a kind of courtyard domestic sewage processing and reclaiming system and the method for disposing of sewage.
Background technology
Traditional wastewater is handled the centralized processing mode that often adopts, and the sewage that is about to different sourcess such as resident family, shop and factory mixes, and concentrated certain fairly large sewage work that is transported to unifies to handle by network of drains.For distance municipal drainage pipe network garden sewage far away, the expense of building the drainage collection pipe network is higher.On the other hand, China belongs to water resources and lacks the area, and reusing sewage is one of economical and effective approach of alleviating the not enough contradiction of water resources.With courtyard domestic sewage on-the-spot disposal, reuse nearby, both can make sewage obtain comprehensive utilization, it is minimum that the cost of disposing of sewage is dropped to.
Sewage decentralized tupe with its layout flexibly, construction is simple and characteristics such as convenient management, in wide popularization and application all over the world.At present, sewage dispersion treatment technology can be classified as three classes on principle both at home and abroad: the first kind is to utilize the principle of the filtration of soil, plant absorbing and microbiological degradation, and custom is ecological treatment system.Commonly used has: underground diafiltration purification system, wet land treating system (artificial and nature) etc., because floor space is bigger, generally be applicable to samll cities and towns and Rural areas, as document " comparison [J] of the artificial composite ecological bed processing domestic sewage in rural areas by using of different depths "; Environmental science .2003,24 (5).Second class is to be the system for anaerobic treatment of representative with three format manure pits, methane-generating pits and upflow anaerobic sludge blanket process, is mainly used in the processing high concentration organic sewage.The shortcoming of upflow anaerobic sludge blanket process is that sludge quantity is big, makes mud be in fluidized state and needs big flow rate of water flow, and maintenance management is had relatively high expectations, as document " UASB handles pig manure waste water starting characteristics test research [J] "; Meteorology and environment journal .2007,23 (2): 34-37.The 3rd class is the aerobe treatment system of giving the sewage oxygenation by power, and this class treatment system facility compact, pollutant removal are good, applied widely, can be used for the processing of various dissimilar sewage.And can with the physical chemistry method combination, make water outlet reach reuse standard according to different requirements to water outlet, water resources is lacked the area have good water saving effect.Commonly used has: conventional activated sludge process, AO method, blodisc and oxidation ditch process.
The SBR method is typical aerobe technology, is widely used at present.Be characterized in stable, effluent quality good, organism, nitrogen, phosphorus are had higher removal, and the structure of reactor compactness, flow process is simple, level of automation is high, occupation of land is few.In the sanitary sewage disposal of hotel and some small-sized Residential areass and reclaiming system, be widely used.But it belongs to activated sludge process in essence, and sludge bulking did not easily take place at that time in operation, and operator are had higher professional requirement.
