Brief introduction

Source:

The wastewater produced by cutting fluid used for cooling, lubricating and anticorrosion in metal processing industry due to corruption and performance degradation

Characteristic:

According to the type of products used in the industry, the water quality and color of the emulsion and cutting fluid wastewater will be different, including a large number of mineral oil, animal oil and vegetable oil, as well as various organic and inorganic additives such as oily agent, surfactant, emulsifier and preservative.

Harm:

Multi frequency use of cutting fluid in production will affect product quality. Because of the high COD and oil content, the waste cutting fluid is toxic and difficult to biodegrade, causing great harm to the environment.

Technical process

When the emulsion wastewater enters the low-temperature evaporator after pre filtration and evaporates under the condition of vacuum and low temperature, the water vapor condenses to form distilled water in the process of vacuumizing and is collected into the clean water barrel; the remaining residue in the distillation kettle is collected into the barrel for further treatment. It can greatly reduce or even remove the harmful chemicals and heavy metals contained in the waste liquid. The evaporation rate of the equipment can reach more than 90%, and the waste liquid can reach the reclaimed water reuse or discharge standard under the condition of pretreatment and post-treatment.
