Study of Earthworms Treating Municipal Wastewater in Cold Regions

Article Preview

Abstract:

Earthworms have synchronous function in sewage purification, sludge stabilization and reduction. Earthworms used in sewage treatment are energy-efficient and high assurance, and show remarkable economic and environmental benefits. The material being in keeping with sustainable development has “ecological equilibrium” and “environment-friendly” two distinct characteristic. This paper analyzes Influence factors of handling techniques. Besides it studies the technical and economic feasibility of technology applied in cold regions and finds a new method for the reuse of sewage and sludge in cold regions.
