Design investigation of a solar energy heating system for anaerobic sewage treatment

Domestic and international researches of solar energy heating for anaerobic wastewater treatment are described in this paper. The design investigation of a solar heating anaerobic sewage treatment system for cold regions is proposed, (I) developing of a solar water heating system for treatment, (II) developing of a high-rate anaerobic reactor for sewage treatment under normal temperature conditions, and (III) solving problems of joint control between the solar water heating system and the anaerobic reactor. This article provides a reference for design and application of the solar energy heating system for anaerobic sewage treatment.
