Technical requirements for industrial wastewater treatment

Mar 21, 2018

Industrial wastewater treatment mainly refers to the use of appropriate treatment measures to treat wastewater back into production, or properly discharge the factory, for various types of wastewater generated during industrial production. These include the management of production water and the measures taken to facilitate the treatment of wastewater. The specific treatment plan for industrial wastewater treatment often depends on the amount and quality of industrial wastewater.


Due to the complex industrial production conditions, there are many factors that affect the discharge of wastewater. Therefore, the process and measures for industrial wastewater treatment are generally determined according to the conditions of field inspections. Among them, a large amount of cooling water is also used in industry. Most of these cooling waters are in contact with different materials, and the quality of used water generally changes little, but the water temperature rises. The liquid and washing wastewater used in the production process (except for the waste water from the papermaking, textile, printing and dyeing industries, etc.) generally have a small amount of water, but the water quality is extremely complicated and the concentration is generally high.


Therefore, in view of such wastewater conditions, we need to analyze to determine a reasonable industrial wastewater treatment process. In this process, we need to understand the main pollution parameters contained in industrial wastewater.

Common chemical oxygen demand, suspended solids, pH and so on.


In general, the reason why we have to carry out industrial wastewater treatment, the ultimate goal is to achieve the recycling of waste water. This can not only make full use of resources, but also reduce or avoid polluting the environment. It is a reasonable measure to prevent and control water pollution.


For ease of understanding, we can analyze the case. For example, in an industrial production, for the specific requirements of industrial wastewater treatment, a plating water circulation system can be used, so that the plating solution brought out of the plating tank by the plating part is recovered, and the environment is prevented from being polluted by harmful substances. In addition, industrial wastewater treatment also requires an economic analysis. When making economic comparisons of the project, it is necessary to estimate the cost of re-use and the water and drainage costs and the environmental benefits received for reuse.
