Device using cyclone separator to sort granular sludge and floc sludge, and use method thereof

Abstract

The invention relates to a device using a cyclone separator to sort granular sludge and floc sludge, and a use method thereof. The device comprises an SBR reactor, a regulating water tank, a main bodycyclone, a floc sludge storage tank, a granular sludge storage tank, a supporting member and an automatic control system; the SBR reactor and the main body cyclone are fixedly arranged on the supporting member, and the regulating water tank is connected with the SBR reactor through a first pipeline; the SBR reactor is connected with the main body cyclone through a second pipeline; the SBR reactoris connected with the floc sludge storage tank through a third pipeline; the bottom flow opening of the main body cyclone is connected with the granular sludge storage tank in series through a fourthpipeline; the overflow opening of the main body cyclone is connected with the floc sludge storage tank in series through a fifth pipeline; and the automatic control system includes a time controller.The device has the advantages of reasonable structure design, reliability in running, low production and operation cost, convenience in later stage maintenance, and high automation degree, and can beused to solve many problems in the prior art.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a device for sorting particles and floc sludge by using a cyclone separator and an application method thereof. Background technique [0002] With the rapid development of China's economy, the accompanying water pollution problem has gradually become the focus of attention. The traditional activated floc sludge technology itself has problems such as high cost, high energy consumption, and unsatisfactory effluent quality. Therefore, it is necessary to develop a new technology and process with low operating cost, low energy consumption and good operating effect to overcome the limitations of traditional processes. [0003] Compared with traditional activated floc sludge, granular sludge technology is becoming a research hotspot due to its good settling performance, high sludge concentration, large biomass, impact load resistance and good effluent quality. The formation of ...

AI Technical Summary

Problems solved by technology

Furthermore, through the study of the stability of aerobic granular sludge and the removal effect on pollutants, it is believed that 500-1900 microns is the optimal particle size range of aerobic granular sludge, but the actual cultivated aerobic granular sludge Diameters from 200-7000 microns have been reported

If the particle size is too large, it will easily lead to the disintegration of the particles, and if the particle size is too small, it will easily cause dissolved oxygen to penetrate into the inside of the particles and fail to achieve the synchronous denitrification effect of the granular sludge.
