I. Choose the right Air Blower When selecting a Air Blower, first of all, it should have sufficient pressure. The blower oxygenates the aeration tank and must overcome the pressure caused by the resis

The inclined pipe sedimentation tank has the characteristics of small area, low cost and high precipitation efficiency, and the unstable water quality may have the following reasons: 1, the change of

1, Roots blower is a positive displacement blower. The Roots blower separates the air intake by the "meshing" of a pair of rotors, which are driven by a pair of synchronous gears and move in

The abnormal sound caused by the Mechanical bar screen operation and the motor heating may be due to the overload of the grating equipment or the motor deceleration leading to the increase of the load

There may be some reasons for the discharge of water mud from the clarifier First, the residence time is reduced due to short flow, so that the floc flows out before settling; At this time, the level

1. Do not start the device when there is no water in the disinfection channel or the water volume does not reach the operating water level. 2. Regardless of whether there is an automatic cleaning mech

Raw water contains a large amount of surfactant components (substances added during the production process, the foam is white, the bubbles are small, light and not sticky). Small bubbles created after

The reasons for the high turbidity of the effluent from the inclined pipe sedimentation tank may be as follows First, the water distribution at the inlet is not uniform, near the inlet, the liquid mov

The reasons for the poor flocculation effect of sewage may be as follows First, the water temperature is too high or too low will affect the effect of flocculant, coagulant hydrolysis is slow, affecti

The septic tank cleaning cycle is not unified provisions, septic tank cleaning cycle is generally determined when the septic tank design, usually divided into 3 months, half a year, one year three dif

Aerobic tank sludge concentration increased quickly or sludge aging led to increased oxygen consumption. There are a lot of suspended solids in the anaerobic pool, which consume a lot of dissolved oxy

If the anoxic tank submersible mixer is broken, the treatment efficiency will be reduced, the concentration of the bottom material will be increased, and the concentration of the oxygen consumption ta
