Problems solved by technology

However, an important problem faced in the process of advancing this work is that the centralized treatment of urban sewage cannot be followed in the control of domestic pollution in townships, and there are still relatively few applicable technologies developed specifically for the control of domestic pollution in towns and towns, and there is a lack of general guidance Functional Technical Standards

Embodiment 1

[0026] Embodiment 1: as figure 1 As shown, choose a natural pond or a leveled site located in the downwind direction of the built-up area of ​​the township, and form three alternate aeration ponds with a water depth of 2-3m through excavation and piled up soil, which are respectively the first aeration pond 10, the second aeration pond Aeration pond 11 and the third aeration pond 13; Lay anti-seepage film around the three alternating aeration ponds, after installing connecting pipes, water inlet pipes, outlet pipes and mud discharge pipes, the first aeration pond 10 and the third aeration pond The three aeration ponds 12 are respectively connected with the second aeration pond 11 through connecting pipes. The water inlet valve 2 and the third water inlet valve 3 are connected to the water inlet pipe 13, the first outflow weir 16 and the first water outlet valve 4 are connected to the water outlet pipe 14 above the first aeration pond 10, and the water outlet pipe 14 is connect...

[0031] Embodiment 2: Using online feedback real-time control mode

[0032] The project in Embodiment 1 can also be operated in the real-time control mode with online feedback. Regardless of the design minimum day, design average day and design maximum day, the real-time operation control mode is as follows: the operation cycle is divided into upper and lower stages. , the ORP in the first aeration pond decreases and the pH increases; when and When the sewage enters from the second aeration pond, close the agitator of the first aeration pond, start the first aerator, the ORP in the first aeration pond rises, and the pH drops; and Close the first aerator to settle for 45 minutes and enter the second half cycle. In the above process, when DO3, the second aerator is turned off; the third aeration pond has always been used as a sedimentation pond, and the solid-liquid separation of the mixed liquid is completed here. The supernatant is discharged through the second outflow...

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...
