A kind of Intelligent sewage treater
Technical field
The utility model relates to sewage treatment area, particularly a kind of Intelligent sewage treater.
Background technology
Along with the raising of China's industrialization degree, the quickening of ur-banization speed, water environmental problems becomes increasingly conspicuous.Current national county town and following samll cities and towns approximately have 50% to fail to reach " urban wastewater treatment firm pollutant emission standard (GB 18918-2002) " standard comprehensively.The situation of Rural areas is more severe.For a long time; the main task of China environmental protection work is control industrial pollution and municipal pollution; limited environment protection resource is almost all configured in alleviates urban environment aspect; and rural environmental protection work is very weak; thereby seriously affected implementing in full of National Sustainable Development Strategies, to this, the Hu Jintao General Secretary, Premier Wen Jiabao repeatedly make important instruction; require rural environmental protection to include national environmental protection total strategy in, plan as a whole to be advanced.Premier Li Keqiang in the national rural environmental protection work teleconference on July 24th, 2008, the clear and definite especially objectives and tasks of national rural environmental protection work." State Council is about advancing Chongqing City to plan as a whole some suggestions of urban and rural reform and development " promulgated by the State Council requires to put forth effort to improve town and country human settlement (2009) No. 3, builds the Upper Yangtze River ecological protective screen.The control of strengthening Pollution from livestock and poultry, sanitary sewage and refuse treatment and secondary stream pollution regulation, strengthen town and country Comprehensive Treatment of Pollution.
China is along with the continuous expansion of town size, and the quantity of villages and small towns sewage and pollution level are all increasing, and villages and small towns water environmental problems has developed becomes the great people's livelihood problem that jeopardizes town dweller's life and health.And thorp sanitary sewage discharge dispersion relatively, discharge capacity inequality, complicated components, space and time difference are remarkable, require the sewage disposal technology that cost of development is low, treatment efficiency is high, anti impulsion load ability is strong.The transformation of existing Sewage Plant is required optimization technological process, reinforced phosphor-removing denitrifying effect, reduces sludge yield etc.
Therefore, the selection of sewage treatment process is the key of sewage disposal, whether treatment process is selected proper, the treatment effect of not only processing, but also affect that the initial cost of whole processing engineering is how many, the complexity of the degree of reliability for the treatment of process operation, working cost height, bookkeeping.
China generally lacks technological standard and the technical parameter for villages and small towns sewage disposal at present, most utilisation technology is applied mechanically urban sewage treatment technology pattern, but China's interzone difference is huge, different to the specific requirement of technique under different water quality, the water yield, weather, landform and different management operating condition, relate to villages and small towns about the technological standard of sewage disposal and the report of technical parameter also very rarely seen.
Therefore, research and development are for the sewage treatment process in villages and small towns, are one of the current sewage disposal technology research fields that should pay close attention to and pay attention to, and market capacity is huge.
