Problems solved by technology

[0003] At present, the DAT-IAT process equipment is unstable when the system is working, the phosphorus removal effect is reduced, and there is a phenomenon of large sludge floating up, and the growth rate of the total phosphorus removal rate is relatively slow; during the actual operation, it is found that the power consumption of the return sludge pump Too large; cell structure and function are often damaged, intracellular polyphosphate is hydrolyzed, resulting in rapid release, the so-called "autolysis" phenomenon, making it difficult to meet the phosphorus index in the effluent

Embodiment Construction

[0009] A kind of sewage treatment equipment based on DAT-IAT technology, comprises regulation pond, DAT-IAT pond, filter pond 9, disinfection pond, reclaimed water storage pond and electric control system, described DAT-IAT pond consists of biological selection pond 4, The DAT pool 5 and the IAT pool 6 are composed of an anaerobic reactor in the biological selection pool 4, and the volume of the anaerobic reactor accounts for 10-14% of the volume of the biological selection pool 4, and the sludge returns to the backflow of the anaerobic reactor. The ratio is 20-25%, and the reflux ratio to the DAT pool 5 is 165-190%. The filter material in the filter pool 9 is a spherical ceramsite filter material, and the surface is provided with some holes. There is a liquid level controller 1, a jet aerator 2 and a buoy type decanter 8, and the DAT pool 5 is provided with a jet aerator 2 and multiple groups of micro-electrolysis suspension fillers 7, and the treatment equipment is also It i...

Abstract

The invention relates to a DAT-IAT technology-based waste water treatment equipment. The DAT-IAT technology-based waste water treatment equipment comprises an adjusting tank, a bio-selecting tank, a DAT tank, an IAT tank, a filtering basin, a disinfecting tank, a recycled water storage tank, and an electrical control system; an anaerobic reactor is arranged in the bio-selecting tank; the size of the anaerobic reactor accounts for 10 to 14% of the volume of the bio-selecting tank; 20 to 25% of sludge is recycled back to the anaerobic reactor; and 165 to 190% of sludge is recycled back to the DAT tank. Effluent of the DAT-IAT technology-based waste water treatment equipment is stable; phosphorus removing effect is improved; floating of large pieces of sludge is not caused; total phosphorus removing ratio is increased quickly; and in practical operation process, return sludge pump power consumption is reduced.

Description

technical field [0001] The invention relates to a sewage treatment equipment, in particular to a sewage treatment equipment based on a DAT-IAT process. Background technique [0002] The main structure of the DAT-IAT system consists of a continuous aeration tank and an intermittent aeration tank connected in series. Under normal circumstances, DAT continuously feeds water and aerates continuously, and its effluent continuously flows into IAT, and the processes of reaction, precipitation, and water effluent are completed in IAT. [0003] At present, the DAT-IAT process equipment, the system effluent is unstable under the working condition, the phosphorus removal effect is reduced, and there is a phenomenon of large sludge floating up, and the growth rate of the total phosphorus removal rate is relatively slow; during the actual operation, it is found that the power consumption of the return sludge pump Too large; cell structure and function are often damaged, intracellular po...
