Problems solved by technology

In practice, the biochemical treatment adopted by most enterprises has a high removal rate of phenolic substances in coking wastewater, but the treatment effect on refractory organic matter is not good, and the effluent COD often fails to meet the national discharge standards. Therefore, it is necessary to seek advanced treatment with good effect and low cost method is po

Abstract

The invention relates to the technical field of wastewater, in particular to a treatment method and system of high-concentration wastewater. The method comprises the following steps: performing flocculation treatment; detecting the size of particles in the wastewater; when the concentration of the particles with the first size is greater than a set threshold value, controlling a screen having themeshes smaller than or equal to the first size to be drawn out so as to allow the wastewater to pass through; preliminarily concentrating the wastewater and accelerating the wastewater entering an adsorption tank; detecting the concentration and pH of macromolecular organic matters in the wastewater; and controlling the addition type of a wastewater treatment agent and the addition type and quantity of a pH regulator according to the concentration and pH of the macromolecular organic matter. By means of the method, the wastewater removal efficiency and the removal rate removal efficiency can be improved to over 99.9% compared with the prior art.

Description

technical field [0001] The invention relates to the technical field of wastewater, in particular to a method for treating high-concentration wastewater. Background technique [0002] At present, with the rapid development of my country's society and industrial economy, the discharge of industrial wastewater is increasing day by day, causing more and more serious harm to water resources, ecological environment and residents' health, and the available high-quality water resources are becoming less and less. Therefore, industrial wastewater Pollution control is the focus of current research in our country. [0003] Coking wastewater is a kind of industrial wastewater that is difficult to treat. Its composition is very complex, and it contains a variety of organic substances that are difficult to be degraded by microorganisms or are biologically toxic, as well as a large amount of inorganic salts such as ammonium salts, sulfides, and cyanides. one of the major sources of polluti...
