Description
Technical field
The utility model relates to technical field of sewage, particularly relates to a kind of gas stripping type integrated sewage treating apparatus.
Background technology
According to statistics, current China total amount of sewage discharge has reached 62,000,000,000 tons, wherein most ofly unprocessedly just directly enter rivers and lakes, the lake of nearly 1/4th is had to receive pollution in various degree, have the cities and towns of nearly 60% not have sewage work, the sanitary sewage of Rural areas is substantially untreated just directly to be discharged.Along with the continuous propelling of the Course of Urbanization, the sanitary sewage of more than 80% will from rural area and cities and towns from now on.2013, China rural area and town domestic sewage quantity discharged reached 30,000,000,000 m
3, and the sanitary sewage of a large amount of dispersion discharge causes severe contamination to underground drinking water source, rainwash and agricultural land soil etc.Along with the continuous propelling of the Course of Urbanization, the sanitary sewage of more than 80% will from cities and towns and rural area from now on.2013, China rural area and town domestic sewage quantity discharged reached 30,000,000,000 m
