1) The cleaning agent of the ultrasonic cleaning machine can be recycled. This cleaning method can save a lot of cleaning agent, each time after using the ultrasonic cleaning machine, it is best to put the cleaning agent into the container, and then pour into the cleaning tank when the next use, the remaining sediment can be disposed of. If the concentration of cleaning agent is not enough, the appropriate amount can be reused by adding a little.
2) Learn as much as possible about the physical characteristics of the cleaning agent. The cleaning efficiency of the ultrasonic cleaning machine can be greatly improved, such as the cleaning agent with low viscosity is suitable for gap cleaning; Low boiling point volatile loss is more, but suitable for steam cleaning; Choosing the appropriate temperature according to different cleaning agents has a great influence on the cleaning effect and so on.
3) Waste liquid treatment problem. Taking water system cleaning agent as an example, because the ultrasonic cleaning machine contains grease and dirt, mud and sand, carbon, metal chips and polar oxides in the waste liquid after cleaning, so that the water quality does not meet the discharge standards, should be treated. General treatment can be divided into three steps:
(1) Use physical methods to settle and filter, remove suspended solids, oil slicks and sediment;
(2) deemulsified oil, salting out, condensation, air flotation and electrolysis are combined to achieve oil separation;
(3) Sewage purification can be used by biochemical method, ozone method, sand filter activated carbon adsorption method, etc.
The wastewater treated by the tertiary process can reach the national wastewater discharge standard.
