It will cost a great amount of money to dispose residual sludge in sewage treatment plants. Considering economic and environmental reasons, it is a big challenge we are faced with to solve residual sludge properly. Owing to the strict demand from environment and relevant laws, it will be stricter and stricter to choose a proper solution for residual sludge. It is an urgent demand to reduce the total volume of sludge. This article pays attention to introduce the main methods to reduce sludge volume. Proper physical environment and running process will reduce the output of residual sludge. But, no matter you adopt which method, microorganisms will be definitely affected. In addition, nitrogen content in disposed water will be higher.
Make use of advanced oxidation technology to produce hydroxyl radical which holds pretty high oxidation potential. Hydroxyl radical holds better performance than majority of oxidation agent. After oxidation-reduction reaction with sludge, polysaccharose substance outside of microorganisms will be degraded. Microbial cells will be broken. After release of organic matters, carbon source and RNA, oxidation and mineralization process will be continued, which will release the compound water and internal water. It will be easier to separate sludge and water, which will provides convenience for dehydration. The volume of sludge will be reduced.
