The reasons for the decreasing amount of aerobic sludge are mainly as follows: 1. Excessive aeration and excessive control of dissolved oxygen value The influence of excessive aeration on the increase

Aeration tank foam is not easy to break the hair sticky is generally biological foam, biological foam is formed by a Nocardia genus of filamentous bacteria, brown, due to increased surface tension and

1, Solid particles adhere to the filter cloth and are not easy to discharge. Once the particles accumulate, the filter hole of the filter cloth will be blocked, which will reduce the efficiency of the

Possible causes of low sludge concentration: 1. The water temperature drops 2. The PH value decreases 3. A large number of low molecular weight dissolved organic matter enters 4. Insufficient N and P

The main shaft of the screw press dehydrator does not rotate: 1, the motor is damaged; It can be solved by repairing the motor or returning to the factory for repair. 2, control system overcurrent pro

Cause of cloudy water ① The aerobic tank sludge load is too small, the aeration is too excessive, the sludge itself oxidizes, resulting in the sludge flocculation being poor, and the sludge structure

Poor denitrification of sewage treatment can be solved from the following aspects: The problem of denitrification in sewage treatment can be solved from the following aspects: 1. The influence of temp

Causes of mechanical seal leakage of agitator (1) There is leakage of the sealing flushing system itself, which leads to the reduction of the sealing flushing pressure, and the flushing liquid cannot

Reduce the surface load of the clarifier tank, that is, the ratio of the unit flow and the area of the clarifier tank. The smaller the load, the higher the precipitation efficiency; add flocculant to

Usually 30 to 40 minutes. Before, ozone has been widely used in water treatment, air purification, food processing, medical, pharmaceutical, aquaculture, and other fields, to the development of these

First of all, the simplest way to improve the precipitation effect of the sedimentation tank is to add enough precipitating agents to the sedimentation tank, so that the precipitating material added t

1, the first thing to tidy up the installation environment when the film is installed, the film removed from the packaging can be placed smoothly, in the installation process may touch the film surfac
