Every year, China's urban sewage treatment plants produce more than 60 million tons of sludge (water content 80%), and the amount of sludge per 10,000 tons of sewage is about 3-8 tons. Due to the long-term problem of "heavy water and light mud", the situation of sludge treatment and disposal is becoming more and more serious. There are a variety of sludge drying technologies, including natural drying, thermal drying, and high drying dehydration. This article mainly talks about sludge drying

The moisture content before sludge drying is very high, the remaining sludge moisture content reaches 99.2% to 99.5%, the sludge moisture content after concentration tank is 95% to 97%, and the moisture content after filtration is about 80%. The reason for reducing the moisture content and sludge drying is that the sludge production in the sewage plant is relatively large, and the sludge volume must be reduced to facilitate subsequent transportation and treatment.
