Description
Technical field
The utility model belongs to technical field of sewage, is specifically related to a kind of novel fixed bed compound bio reactive system, is applicable to the processing and the advanced treatment and reclamation of sewage, trade effluent.
Background technology
Water is irreplaceable resource at nature.China's water resources ownership per capita only is equivalent to 1/4 of world's water resources ownership per capita, ranks the 121st in the world, is " water scarcity " country that United Nations is assert.There is more than 400 lack of water in the whole nation in 668 cities, and the city that wherein lack of water is more serious has 110, and a day water deficit reaches 1600 ten thousand steres.Therefore, Future in China water resources situation is very severe, and influence industrial outpuut because of the water yield is in short supply and reach 2,300 hundred million yuan every year, and drought and water shortage has become one of most important factor of restriction China's economic social development.In addition, be accompanied by the cutout that trunk river downstream and master stream generally occur and the decline significantly of ground water table, also caused problem like deterioration of the ecological environments such as sandstorm take place frequently.
Urban water shortage is very serious on the one hand, and a large amount of on the other hand municipal effluents run off in vain, have both wasted resource, again contaminate environment.By the end of the year 2010, China's city domestic sewage total emission volumn will reach 1,050 hundred million m
3, wherein the domestic sewage of villages and small towns discharging can reach 27,000,000,000 m
3Yet China's city domestic sewage processing rate is merely about 20%, and the wastewater treatment rate of samll cities and towns is less than 10%, and the processing rate of the regional sewage of remote dispersion is lower beyond the city, and most sewages through just handling directly discharging, do not cause waste.
Municipal effluent can get, be easy to collect nearby.Manipulation of regeneration is more with low cost than sea water desaltination, and treatment technology is comparative maturity also, initial cost far below desalinize seawater, remote diversion etc.When various countries, the world today solved water shortage problem, the municipal effluent regeneration was chosen as reliable second water source.For implementing China's water resources development strategy and water prevention and cure of pollution policy, alleviate the water scarcity situation, promote city and economic construction Sustainable development, research and the reuse of enforcement city sewage deep treatment are extremely important.
The utility model content
The utility model purpose is to provide a kind of novel fixed bed compound bio reactive system, is applicable to the processing and the advanced treatment and reclamation of sewage, trade effluent, and is effective.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of novel fixed bed compound bio reactive system; Comprise Aerobic Pond, wherein, the support orifice plate is set at the Aerobic Pond middle part; This is provided with biomass and/or mineral filler layer above support orifice plate (the most handy supported hole plate separates between the different packing layers; Support orifice plate and be fixed on the pool wall, the integral body that the utility model will support orifice plate and packing layer is called " fixed bed ", down together).
