Have you ever treated the waste water after using the ultrasonic cleaning machine to finish the cleaning work easily? Do you know the harm of wastewater from ultrasonic cleaning fluid? It's everyone's responsibility to maintain the environment, so let's popularize the science of the harm of ultrasonic cleaning liquid wastewater and the main methods of disposal!
First of all, to understand the source of ultrasonic cleaning fluid wastewater from the harm, ultrasonic cleaning wastewater mainly comes from the use of ultrasonic and ultrasonic cleaning agent to clean objects. The waste water contains oil and special surface active agent, which has high COD content, high suspended solids concentration and low biodegradability. If the pretreatment is not stopped, it is difficult to stop the biochemical degradation. If it is directly discharged into the environment, it will cause serious damage to the environment, directly affect people's health, and the level of harm is great!
Understand the harm of ultrasonic cleaning liquid waste water, know how important it is to treat it after use! At present, the main treatment methods of ultrasonic cleaning solution wastewater are: coagulation sedimentation + biochemical; Fenton oxidation + biochemical coagulation sedimentation + biochemical: coagulation method is to add coagulant to the wastewater.
Coagulant in the sewage to tighten the electric double layer, adsorption surface neutralization, adsorption bridging and precipitation network capture, so that fine suspended particles and colloidal particles can be integrated into coarse particles and precipitated, separated from the water, so that the sewage can be purified. The water after coagulation treatment is discharged into the biochemical system for further treatment, and finally reaches the discharge standard.
