Anti-deterioration process of cutting fluid based on microorganism

Abstract

The invention provides an anti-deterioration process of cutting fluid based on microorganism, which composed of five modules, namely a filtering module, a sterilizing module, a dirty oil treatment module, a hardness repairing module and a pH repairing module. The specific process comprises the following steps: collecting dirty oil on the surface of the cutting fluid, sterilizing, treating oil stain, repairing hardness, repairing pH, and finally refluxing to a cutting fluid tank. According to the invention, the defects in the prior art are overcome, rhamnolipid generated by the pseudomonas aeruginosa is utilized, the dispersion effect of dirty oil in the cutting fluid is improved, the degradation efficiency is improved, and meanwhile the emulsification effect and solubility of the dirty oil can be improved; alcaligenes faecalis can be used for solving the problem that the pH value of the cutting fluid is reduced in the long-term use process, bacillus can be used for solving the problem that the hardness of the cutting fluid is increased, and the service life of the cutting fluid is effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of cutting fluid reuse, and in particular relates to a cutting fluid anti-deterioration process. Background technique [0002] As a medium widely used in the machining industry, cutting fluid plays an important role in cooling, lubrication, and rust prevention. The annual consumption of cutting fluid in my country exceeds 10 million tons, and the usage is showing an increasing trend. However, the treatment of cutting waste fluid produced by the deterioration of cutting fluid during long-term use has become a problem that has long plagued the industry. The discharge of untreated cutting waste liquid into natural water bodies will seriously pollute the environment and threaten the growth of aquatic organisms. In addition, harmful components in waste liquid will enter the human body through the food chain, causing cancer risk and endangering human health. Due to the characteristics of high COD, high turbidity...

AI Technical Summary

Problems solved by technology

At present, some researchers have found that certain substances produced by microorganisms with specific functions can increase the pH in water and promote the dissolution of oil slicks. They are often used in the wastewater treatment industry, and there are rare reports on the anti-deterioration of cutting fluids.
