Description

technical field [0001] The invention relates to an energy-saving and environment-friendly equipment for safe disposal and resource utilization of solid waste (sludge), especially related to an integrated treatment system for sludge drying, pyrolysis, gasification and incineration. Background technique [0002] Since the "Eleventh Five-Year Plan", my country's sewage treatment industry has developed rapidly, and its daily treatment capacity has exceeded 100 million tons. The rapid growth of sewage treatment capacity and treatment rate has also brought about a rapid increase in sludge production. According to statistics, the annual sludge output of only urban sewage treatment plants in my country has exceeded 30 million tons, and there are still a large amount of industrial sludge. speed growth. [0003] Sludge is the sediment produced in the process of sewage treatment. It is a solid-liquid mixture composed of complex heterogeneous bodies such as organic debris, bacterial ...
