Research on residual sludge disposal and resource utilization technology of urban sewage treatment plant

Abstract

Urban sewage treatment plants play a pivotal role in the process of urban sewage treatment in China, but due to the implementation of the daily urban sewage treatment process will appear a large number of residual sludge, if not timely and properly disposed of, it will affect the surrounding natural environment, and even endanger human health. Therefore, taking effective measures, such as reasonable treatment of sludge, can efficiently convert waste into resources and achieve efficient use of resources. This paper aims to deeply explore the most commonly used sludge treatment technologies, and compare and analyze the advantages and disadvantages of various technologies, in order to provide useful suggestions and references for environmental protection and engineering applications.
