With the continuous development of society, science and technology, and industry is in rapid development, growing economy, at the same time also brought a lot of pollution. With the development of the concept of environmental protection, pollution to the environment management is particularly important.

at present, the domestic many chemical companies in the process of organic chemical products production will produce large amounts of waste water, such as, sodium nitrate wastewater, nitrophenol wastewater, etc. Among them, the phenolic wastewater is a kind of highly toxic waste water, causing serious pollution to the environment and people, therefore, the industrial wastewater containing phenol in water pollution control in our country is listed as one of the key to solve harmful waste water.

phenol compounds are important chemical raw materials or intermediates, also is a byproduct of many industrial and mining enterprises production. Direct emissions wastewater containing phenol, have very big harm to human and aquatic life, agriculture, waste water containing phenol in water pollution control in China As a key to solve one of the poisonous and harmful waste water, must first, after in addition of phenol to achieve environmental protection requirement to emission.

in the processing of phenolic wastewater, solvent extraction effect is good, a method of processing small investment. In practice, adopting the mutual miscibility with water but can dissolve contaminants extraction agent, after contact with the waste water to mix adequately, use of pollutants in the water and solvent in different points compared with a waste water purification method for separation and extraction of pollutants. Contain by extract of extractant recycling reverse extraction, the extraction agent for recovery of useful substances, and make the extractant regeneration and reuse.

operation process wastewater containing phenol:



waste water containing phenol using solvent extraction process, common equipment is. cwl - zhengzhou days extraction technology research and development production M series centrifugal extraction machine, under the same processing conditions, the series of centrifugal extraction machine power consumption is only 10% ~ 30% of traditional ring gap model. At the same time, the centrifugal extraction machine level reserved time is short, split phase quickly, high extraction efficiency, save the investment cost and solvent recycling fee.
