The methods of slaughtering wastewater treatment mainly include the following:
1.Physical Treatment:Through physical action, the suspended solids, impurities and harmful substances in the wastewater are separated to achieve the purpose of purifying and stabilizing the water quality. Commonly used physical treatment methods include precipitation, filtration, centrifugal separation, flotation, etc.
2.Chemical Treatment:Through chemical reactions, the harmful substances in the wastewater are converted into harmless or low-toxicity substances to achieve the purpose of purifying and stabilizing water quality. Commonly used chemical treatment methods include neutralization, precipitation, redox, adsorption, etc.
3.Biochemical Treatment:The metabolism of microorganisms is used to convert the organic matter in the wastewater into harmless or low-toxicity substances to achieve the purpose of purifying and stabilizing water quality. Commonly used biochemical treatment methods include activated sludge method, biofilm method, anaerobic biological treatment method, etc.
The following will introduce these slaughtering wastewater treatment methods in detail:
1.Physical Treatment:
The sedimentation method is to settle the suspended solids and impurities in the wastewater through the principle of gravity sedimentation, so as to achieve water purification. The filtration method is to intercept the suspended solids and impurities in the wastewater through the filtration of the filter material, so as to achieve the purpose of purifying and stabilizing the water quality. Centrifugal separation method uses centrifugal force to separate suspended solids and impurities in wastewater. The flotation method is to flotate the suspended solids and impurities in the wastewater through the buoyancy of the bubbles.
2.Chemical Treatment:
The neutralization method is to neutralize the acidic or alkaline substances in the wastewater by adding acid or alkaline substances to achieve the purpose of purifying and stabilizing the water quality. The precipitation method is to convert the harmful substances in the wastewater into sediment by adding a precipitant, and then separate them through sedimentation. The redox method is to oxidize or reduce the harmful substances in wastewater to harmless or low-toxicity substances by adding oxidants or reducing agents. The adsorption method is to adsorb the harmful substances in the wastewater on the surface of the adsorbent through the adsorption of the adsorbent, so as to achieve the purpose of purifying and stabilizing the water quality.
3.Biochemical Treatment:
The activated sludge method uses aerobic microorganisms in activated sludge to convert the organic matter in wastewater into harmless or low-toxic substances through its metabolic action. The biofilm law is to use the microorganisms in the biofilm to convert the organic matter in the wastewater into harmless or low-toxic substances through their metabolism. The law of anaerobic biological treatment is to use anaerobic microorganisms to convert organic matter in wastewater into harmless or low-toxic substances such as methane and carbon dioxide through their metabolic action.
The above are several methods of slaughtering wastewater treatment and their detailed introduction. In practical application, it is necessary to select the appropriate combination of methods according to the actual situation to achieve the best treatment effect. Basics of sewage treatment.
