High-salinity industrial wastewater advanced treatment and recycling process

Abstract

The invention relates to the technical field of high-salinity industrial wastewater treatment, and discloses a high-salinity industrial wastewater advanced treatment and recycling process which comprises a filtering box body, a neutralizing box body is arranged on one side of the filtering box body, a settling box body is arranged on the other side of the neutralizing box body, and an ultrafiltration device is arranged on the other side of the settling box body. According to the high-salinity industrial wastewater advanced treatment and recycling process, by arranging the neutralizing box body, when the wastewater enters the neutralizing box body, the neutralizing solution is added into the neutralizing box body for the neutralization reaction, the motor works to drive the first rotating shaft to rotate, and the first rotating shaft drives the first stirring rod to rotate so that the efficiency of the neutralization reaction is accelerated; meanwhile, the driving wheel arranged on the output shaft of the motor rotates, and the driven wheel is driven to rotate under the action of the belt so that the second rotating shafts on the two sides of the first rotating shaft rotate, the second rotating shafts drive the second stirring rods to rotate, and the neutralization reaction is further accelerated.

Description

technical field [0001] The invention relates to the technical field of high-salinity industrial wastewater treatment, in particular to a high-salinity industrial wastewater advanced treatment and reuse process. Background technique [0002] Industrial wastewater includes production wastewater, production sewage and cooling water. It refers to wastewater and waste liquid produced in the process of industrial production, which contains industrial production materials, intermediate products, by-products and pollutants produced in the production process lost with water. Some Industrial wastewater contains a large amount of industrial salt. [0003] When the existing device treats high-salinity industrial wastewater, it needs to carry out neutralization reaction, so that the pH of the wastewater is neutral. The existing device adds the neutralizing solution to the wastewater without setting a stirring mechanism, so that the neutralizing solution is neutralized. And the efficienc...

Problems solved by technology

[0003] When the existing device treats high-salinity industrial wastewater, it needs to carry out neutralization reaction, so that the pH of the wastewater is neutral. The existing device adds the neutralizing solution to the wastewater without setting a stirring mechanism, so that the neutralizing solution is neutralized. And the efficiency is low, which affects the efficiency of the overall wastewater treatment, and when the wastewater is initially filtered, a large amount of solids remain in the filter device after filtration, requiring workers to enter the filter device for cleaning, resulting in a waste of a lot of manpower and time to clean up
