Sludge agriculture application in future will be one of the main sewage sludge disposal ways in China. To ensure safety and environment of sewage sludge agriculture application, except to strengthen the research of sludge heavy metal, pathogen outside the organic contaminants will be one of the focuses of the future research, especially to strengthen the PAHs and NP/NPE. In order to reduce the environmental risks of sludge agriculture application, using biological aerobic fermentation processing technology treatment sludge can effectively reduce the organic contaminants, depress secondary pollution problem, which sewage sludge brings.

SynopisA general survey of the biomass of the benthic infauna of the Clyde Sea Area and the distribution and abundance of the dominant species throughout the area, based on data from surveys undertaken in 1972 and 1974, is described. Recent surveys of the distribution of species along a well-defined gradient of organic enrichment on the Garroch Head sewage sludge disposal grounds in the central Firth of Clyde are used comparatively to suggest that benthic populations in the inner sea lochs, Kilbrannan Sound and in areas along the Ayrshire coast are markedly enriched. It is suggested that this enrichment may be caused by a general eutrophication of the Clyde Sea Area enhancing the effects of localised carbon inputs from urban areas.

Technical control of sewage sludge disposal to sea is carried out primarily to maintain the quality of the receiving environment and this paper discusses the control in the context of England and Wales. Control is exercised in several ways and by several bodies. There are international conventions and national legislation governing sludge dumping, the national legislation is enforced by the Ministry of Agriculture Fisheries and Food, who stipulate the required quality and quantity of sludge. The sludge is produced and disposed of by regional water authorities who must control the quality of their sludge and use trade effluent legislation to control effluent from industry. In turn industrialists must control their effluents to meet water authority standards and this usually requires the installation of water treatment equipment or even change of process. At all stages scientific methods are used to check the effect of the legislative control. It is important that the technical controls used to protect the environment are not over-stringent so that an economic and practicable method of sludge control is not wasted.

Industrial drying techniques are successfully used processes. They are usually used for the production of base materials for industries such as food, chemical and pharmaceutical. These processes can be transferred without any difficulty for the drying of sewage sludge. Thermal drying as a process for the purpose of water removal is an important link in waste management between sludge production and sludge disposal. Two systems, convection and contact drying, are here compared. Contact drying in the thin film evaporation process is explained. Explanation and proposed uses of the single and two-stage drying systems will be discussed. Finally a short review of incurred expenses will be given.
