Description :
WSZ-0.5 integrated sewage treatment equipment
Lusheng Environmental Protection's equipment has undergone rigorous quality control, with high water output and long service life. After passing inspection, it is sold after leaving the factory, and there is no need to worry about the quality. After sales service is more comprehensive, action is better than excitement, thousands of inquiries are better than picking up the phone at once. Welcome to visit our company for inspection.
1、 Definition of sludge
Sludge is a byproduct of sewage treatment, which refers to various sediments and floating materials generated during different treatment processes in water supply and wastewater treatment. Whether it is activated sludge and its derivative technology, or membrane treatment technology, sludge will be generated in the sewage treatment process. Sludge concentrates harmful substances in wastewater, with over 50% of organic pollutants entering the sludge. It also contains pathogenic microorganisms, heavy metals, and other pollutants. Therefore, not treating sludge is equivalent to not treating wastewater, and the concentrated pollutants will cause greater pollution to the environment, which can easily lead to secondary pollution.
2、 Technical route for sludge treatment
Sludge treatment refers to the process of reducing, minimizing, and rendering harmless the original sludge.
Complete roadmap of sludge treatment technology
From a process perspective, sludge needs to go through multiple processes such as concentration, conditioning, dewatering, stabilization, drying, or incineration.
Sludge disposal process diagram
Overall, the sludge treatment and disposal plan requires three main steps: pretreatment, sludge concentration and dewatering, and back-end disposal. Sludge pretreatment and dewatering can be said to be the necessary treatment processes for various back-end disposal schemes, and back-end disposal schemes need to be comprehensively considered based on multiple factors.
Roadmap of different technologies for sludge disposal
The disposal of sludge can form multiple technical routes by combining basic methods. The currently dominant landfill technology route will be replaced, while collaborative incineration, anaerobic digestion, and aerobic fermentation technology routes will be the mainstream technology choices in the sludge treatment and disposal market in the future.
3、 Comparison of evaluation of sludge treatment technology routes
The overall idea for the development of sludge treatment technology is to achieve harmlessness, stabilization, reduction, and energy resource utilization. Harmlessness and stabilization are fundamental requirements for various treatment technologies, and the most thorough method is incineration and subsequent treatment of fly ash; In the requirement of mass reduction, quenching and tempering and wall breaking are the key links to achieve breakthrough; Anaerobic digestion and co incineration are the development directions in energy resource utilization.

4、 Summary and sorting of the sludge treatment industry chain and related companies
The sludge treatment market is currently in its infancy, and the treatment scale of various companies in the industry is relatively small with a high degree of dispersion, basically at a disposal scale of less than 1000 tons per day.
At present, there are many directions for the exploration of core technologies by major companies in the sludge industry, but in general, incineration is still the main approach.
