Description

technical field [0001] The invention relates to a sewage and sludge treatment system, in particular to a treatment component for drying domestic sewage and sludge in a town. Background technique [0002] With the enhancement of people's awareness of environmental protection, sewage treatment has become a key issue of concern to governments of various countries. There are three main sources of sewage in my country, namely, decentralized domestic sewage in township residential areas, centralized domestic sewage in urban living areas, and industrial production processes. sewage. Using sand to purify sewage is a traditional sewage treatment method. The existing sewage treatment method has some shortcomings. The removal capacity of TN and TP is low, and some biochemical treatment ponds such as denitrification ponds need to be placed. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides another component for drying dom...
