How to take the certificate of industrial wastewater treatment worker?Is the exam difficult?
Sewage needs to be treated by a screen. The grid is made of a set of metal grids arranged in parallel and is able to intercept large pieces of material in the sewage, such as tree branches, garbage, etc.
Next, the effluent enters the grit tank. The function of the grit tank is to remove substances such as sediment and heavy metals from sewage. These substances settle down in the grit tank to form sludge.
The effluent then enters the conditioning tank. The function of the regulating tank is to regulate the flow rate and pH value of the effluent to suit the subsequent treatment process. The sewage in the regulating tank needs to be aerated to increase the oxygen content of the sewage and promote the decomposition and removal of organic matter in the wastewater.
Aeration tanks are an important part of the wastewater treatment process. In the aeration tank, the organic matter in the sewage is decomposed into carbon dioxide and water by microorganisms, while the microorganisms will adsorb and degrade other harmful substances in the wastewater.
Finally, the treated effluent from the aeration tank enters the secondary sedimentation tank. The function of the secondary sedimentation tank is to remove suspended solids and microorganisms and other substances in the sewage. These substances settle down in the secondary sedimentation tank to form sludge. The sludge needs to be cleaned regularly to ensure the normal operation of the secondary sedimentation tank.
