Improving the systems for surface runoff treatment

Abstract

The issues of improving the treatment of surface runoff (SRO), generated on the territory of communities of various functionality, in particular, the design of flow-type local facilities for surface runoff treatment are considered. It is noted that SRO generated on the territory of cities and communities is an intensive source of technogenic pollution of water bodies and affect the ecological safety of the urban environment. Herewith, to the front burner go the issues of developing advanced process systems for SRO treatment that provide for applying the latest developments of the sectoral research; as well as of upgrading the existing process schemes for SRO treatment, with account of the new approaches to the regulation of the pollution discharge into water bodies. The paper discusses the principle of decentralization of surface runoff treatment systems using biological treatment facilities. Based on experimental studies of the SRO composition the paper presents a list of the priority pollution indicators needed for designing SRO treatment systems. The recommended classification of flow-type SRO treatment facilities widely used in the engineering design, is given. The paper describes a new design of a flow-type SRO treatment plant developed as a result of the experimental studies with real SRO with a utility patent obtained.
