Embodiment Construction

[0026] The present invention will now be described in further detail with reference to the drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner.

[0027] Example:

[0028] One, such as figure 2 , image 3 As shown, an improved energy-saving AAO rural domestic sewage treatment device is built, including the sewage inlet pipe network, the grid 1, the regulating tank 2, the anaerobic tank 3, the lift pump 9, the anoxic tank 4, and the aerobic tank 5 connected in sequence. , Blower 11, oxygen-containing mixed liquid distribution tank 6, sedimentation tank 7, water outlet pipe, sludge storage tank 8 and sludge return pump 10. Except for the sewage inlet pipe network and the outlet pipe, all other sewage treatment units and sludge storage tanks are designed with reasonable effective volumes according to relevant design parameters, and are arranged in a whole sewage treatment structure, sepa...

Abstract

The invention discloses an improved energy-saving AAO rural domestic sewage treatment method. The method comprises the steps that 1, an improved energy-saving AAO rural domestic sewage treatment device is built, and the device comprises a sewage water inlet pipe network, a grille, an adjusting tank, an anaerobic tank, a lifting pump, an anoxic tank, an aerobic tank, a blower, an oxygen-containing mixed liquid distribution groove, a sedimentation tank, a water outlet pipe, a sludge storage tank and a sludge return pump which are connected in sequence; 2, a sewage collecting pipe network is laid by taking a natural village as a unit, and after sewage is treated by the improved energy-saving AAO rural domestic sewage treatment device, clear water flows automatically for discharging. According to the technology, the position of the lifting pump in the process and the height of the anaerobic tank are adjusted, an oxygen-containing mixed liquid return pump is canceled, the function of AAO in the technology is not affected, and treatment effluent meets the emission standard; one pump can be reduced in management, and management is simplified. By means of the technology operation mode, the lifting pump flow is increased, pump type selection tends to be reasonable, energy consumption can be saved, and the operation cost can be lowered.

Description

Technical field [0001] The invention relates to the field of environmental protection engineering, in particular to an improved energy-saving AAO rural domestic sewage treatment method. Background technique [0002] In recent years, the problem of rural domestic sewage has become one of the reasons for the aggravation of agricultural pollution. Its pollution scale is small, the composition is complex, the fluctuation is large, the concentration of suspended solids is high, and it is restricted by the local social and economic conditions. According to investigations, there are no drainage channels and sewage treatment systems for small-scale sewage treatment across the country, and sewage is discharged at will, causing serious river water and environmental pollution. However, with the development of society, the amount of small-scale, organized sewage treatment will inevitably increase, and the energy consumption will also increase accordingly. How to rationally arrange and optimi...
