Review of Sludge Reduction Technology in the Wastewater Treatment Plant

Abstract

Whether water treatment or sewage treatment, it is necessary to increase the analysis and implementation of sludge reduction technology. In the process of wastewater treatment, by adding enzymatic hydrolysis technology, mechanical disposal technology, processing technology, thermal decomposition, and other technical means, the gas in the cells will be released, and then the cells will be sent back to the activated sludge tank to further degrade the dissolution generated by cell rupture, resulting in the reduction of sewage. Sludge reduction technology further reduces the cost of sewage production and treatment through sludge anaerobic discharge, sewage distillation decomposition, sludge drying, sludge incineration, and other treatment processes. Based on this, through the selection and comparison of various sludge reduction technologies, clearly == analyzed the advantages and disadvantages of various technologies that can be used as a reference for other sewage sludge reduction.
