| In recent years, our country economy is of great leap forward development, environmental problem is particularly prominent, from the "environment door" event recently discovered, hand highlights many people environmental protection consciousness is weak, the lack of consciousness of social morality, on the other hand, many construction good environmental protection treatment facilities can not run normally, the main reason is the environmental protection work do not make money, more run more deficit.In view of the present situation, we should vigorously develop a environmental awareness of the whole society, also to study environmental feasible treatment measures, so that environmental protection facilities built up, running well, the clear water and blue sky, clean and tidy environment.Waste water treatment in small towns and residential areas, hotels and other units, because the emissions is small, there is no need to sewage treatment plants to deal with large, and waste and sewage into drainage channels actually have2pollution, so treatment system for small and medium scale better to meet their needs. Processing system on this question involves mainly the type system of the medium and small scale nitrogen, phosphorus treatment, the discharge water quality system after treatment, to reach the discharge standard, can be discharged into sensitive water as well as other uses non potable water.This paper is on a medium-sized comprehensive business building (logistics training building) washing, bath, kitchen sewage treatment, water treatment for fire protection, the toilet back flushing, car washing, green; feces, kitchen waste fermentation, production of biogas for power generation, heat source to provide hot water, steam conversion heating for buildings used for biogas residue, biogas slurry, into the production of organic fertilizer, feed, breeding for ammonia recovery, resulting in the production process (odor source), as other enterprises of raw materials. To achieve zero emissions outside through scientific processing, automation (garbage, sewage, gas), the comprehensive utilization of energy, resources, play a good social and economic benefits. |
