With the process of urbanization in China, urban domestic sewage has always been a major problem in the industry. Because sewage treatment needs to be met, first, sludge sludge treatment, can not be incinerated or landfill, can not cause secondary pollution; second, it is necessary to treat harmful substances and nutrient substances in the water, active fungal groups, etc., nitrogen, phosphorus, Potassium and other nutrients are extracted and used twice.

First of all, for the treatment of sludge slurry, filter press equipment can be used. Nowadays, the filter filter equipment is generally not required for the dryness of such filter residue, and the sludge and water in the sewage can be effectively separated. Pave the way for the next step.

Thirdly, in the treatment of separated water, a phosphoric acid dissolving agent and a hardening agent for solidifying heavy metals are added to the water, and a trace amount of harmful heavy metals in the water are also treated to prevent harmful heavy metals from entering the food chain, and a biological drying separating agent is added to the water again, and fermentation of these bacteria is performed. Reaction, pathogenic microorganisms and odors in the water. Then you can think of ordinary water treatment and use it again.

Secondly, for the treatment of the separated mud, the mud will also extract harmful substances, which are then burned and landfilled.

For the treatment of domestic sewage, it is simple to say that this is. We can now use these resources again because of the continuous advancement of our technology and the production and development of various mechanical equipment.
