Abstract
The invention pertains to the technical field of environment protection, and particularly relates to a simple sewage treatment device of an alternate aeration basin and a treatment technique thereof, wherein the treatment device comprises the aeration basin, an aerator, a water inlet pipeline, a water outlet pipeline, a sludge discharge pipeline, a communicating pipeline and a control valve. In implementation, a natural pond or flat field in the downwind direction in a built-up area of villages and towns is selected, and the alternate aeration basin is formed by excavation and mounding; an impermeable membrane is laid around the alternate aeration basin, bricks are laid on the impermeable membrane after the communicating pipeline, the water inlet pipeline, the water outlet pipeline and the sludge discharge pipeline are installed, and cement mortar is plastered, thus completing the construction of the basin body. Then, the aerator or a mixer, an electric / pneumatic valve and the control system are installed, and then the sewage treatment device can be put into service and used. The sewage treatment device adopts a timing control mode of set time or a mode of online feedback real-time control for sewage treatment. The sewage treatment device has high treatment efficiency, small occupied area, and has low capital investment and short construction cycle compared with UNITANK and alternative oxidation ditches of three ditches; and through matched set time or real-time control of operation, the system can be suitable for shifty water quality and quantity of sewage in villages and towns, and can runs automatically.
Description
technical field
[0001] The invention belongs to the technical field of environmental protection, and in particular relates to a simple alternate aeration pond sewage treatment device and a treatment process. Background technique
[0002] It has always been one of the important strategies for the development of rural economy in my country to drive rural economic and social development through the development of towns with relatively good economic foundations. Townships generally refer to smaller cities and towns, mainly including market towns and official towns. Market towns refer to the seat of the township government and non-incorporated towns developed from markets, and organic towns refer to towns established by the state according to the administrative system but excluding county towns. Townships are often the economic, cultural and life service centers of rural areas in a certain area. According to the 2007 Statistical Bulletin on City, County and Village Construction...
