SBR Activated Sludge Machine

Product Description

Imported equipment is troublesome to purchase, and the price is expensive. At the same time, the maintenance cost will be high in the future. The sludge concentration in the SBR method pond is measured by a concentration meter in order to control the amount of excess sludge discharged. At present, the quality of the domestic concentration meter is not good enough, which makes it difficult to control the sludge discharge.

1 Analysis of sewage volume and water quality
According to the characteristics of this type of wastewater, the process flow combining physical and chemical treatment is determined. The physical and chemical treatment adopts coagulation sedimentation.
2 Sewage biochemical treatment process plan selection
2.1 Comparison and selection of sewage biochemical treatment technologies
Small sewage treatment stations generally adopt the following biological treatment methods.
A) Biological contact oxidation method
The biological contact oxidation method belongs to the biological membrane method. The process is equipped with a new type of elastic three-dimensional filler. It has the advantages of high load, no sludge expansion, small facility size, stable and testable operation, and convenient management. It can protect the sewage after treatment. All indicators are fully up to standard. The selected packing is easy to maintain and replace, and the service life can reach more than 10 years. Generally applicable to small sewage treatment stations.
B) Conventional activated sludge method
The conventional activated sludge method is widely used in large-scale sewage treatment. However, due to the low load of the conventional sludge method, sludge expansion is easy to produce, and it is difficult to control and manage, it has been used less and less in small sewage treatment stations in recent years.
C) SBR method
The SBR method is a relatively recent activated sludge treatment method developed in recent years. The treatment process integrates aeration tank and sedimentation tank, continuous water inflow, intermittent aeration, and sewage precipitation when the gas is stopped to remove the supernatant. , Becomes a cycle, repeating itself again and again. The SBR method does not have a sedimentation tank and no sludge return equipment, but the SBR method operates intermittently and requires multiple processing units, and the water intake and aeration are switched mutually, which makes the control more complicated. In order to guarantee the overflow rate, the SBR method has high requirements for the manufacturing of decanter equipment, and must be lean in the production, otherwise it is very easy to cause the water quality of the drunk to fail to meet the standard. At present, there is no decanting equipment of better quality in China.
