With the acceleration of the process of urban modernization, the population continues to increase, resulting in the continuous increase of urban water consumption. The water pollution problem has become increasingly serious, which has adversely affected the quality of life of urban residents. Actively dealing with urban water pollution has important practical significance.

Filter technology

This is the basic method of physical treatment of sewage. A filter layer is established where the sewage flows. This layer is mainly a granular filter layer composed of quartz, sand, etc., which can intercept impurities in it to achieve a purification effect.

Separation technology

Separation is a technology that uses the principle of the density difference between impurities and water to separate and treat sewage. Pollution impurities with low density will be suspended on the water surface, and then the impurities will be completely separated out using related equipment, such as centrifuges.

Precipitation technology

Usually used in sewage with a lot of sludge, it mainly includes two sedimentation processes, the first sedimentation is carried out before the sewage is sent to the treatment equipment, and the second is to clean up in time after the sludge is completely sedimented to purify the sewage .

The innovation model integrates various methods

Under the background of the technological age, many advanced urban sewage treatment technologies have been proposed. In addition to the commonly used technologies mentioned above, such as: biofilm technology and activated carbon technology have been actively adopted. Each comprehensive technology has its own unique advantages.

Biofilm Technology

This technology has the characteristics of good effect, low capital and low cost. It mainly adopts the cultivation of microbial strains to produce effective preparations. When this preparation is put into sewage, biofilms will appear to purify water quality. .

Adsorption technology

The main material of this technology is to use the adsorption performance of activated carbon to treat sewage. This can change the color of sewage and purify the smell of sewage, which is a scientific method of water pollution treatment.

Oxidation technology

Most of this technology is closely related to the chemical oxidation reaction, and its advantage is that it is simple to operate and can purify sewage without too many treatment devices.
