Municipal Sludge Management Planning and Policy Options

摘要

The purpose of the study is to: introduce municipal public decision makers to the issues relating to wastewater treatment plant sludge production treatment and use/disposal. The report is organized as follows: Chapter Two gives a description of basic wastewater treatment processes and how these processes effect sewage sludge quantity and quality. The chapter also explains the impact of sludge characteristics on use/disposal options. Chapter Three discusses the factors which will effect the selection of sludge-treatment alternatives. These factors are discussed in a generic nature with ample references to the applicable regulations and guidelines. Interactions between technology, socio-political considerations, site requirements, and other factors which are necessary to match a sludge-treatment solution to the needs of the community are discussed. Chapter Four gives technical details on currently available sludge-treatment technologies applicable to Illinois. The chapter utilizes the information described in Chapter Three to illustrate which types of constraints there are for each of the technologies.
