Abstract

The invention discloses a high concentration wastewater treatment device which produces methane highly effectively, belonging to the equipment device used for environmental engineering. The device which is full-automatic, with methane effectively produced, and with organic wastewater anaerobic treatment, comprises mainly of a novel expanded granular sludge bed (shortly called EGSB), a reactor, and a computer monitoring system. The device can effectively treat organic wastewater, and at the same time it can produce methane highly-effectively. And it provides a perfect environmental engineering equipment device for the effective treatment to organic wastewater and scope-production of methane.

Description

technical field [0001] The invention relates to a novel high-efficiency biogas-producing wastewater treatment device, which belongs to equipment used in environmental engineering. Background technique [0002] Anaerobic reactors include both traditional reactors and modern high-efficiency reactors. After more than a hundred years of development, the anaerobic process has developed from the first generation of anaerobic digesters to the second generation of anaerobic filters (AF) , anaerobic fluidized bed reactor (AFB), upflow anaerobic sludge bed reactor (UASB) and the third generation of expanded granular sludge bed reactor (EGSB and IC) in various reactor forms. With the advancement of industrialization, the problems of energy crisis and environmental pollution are becoming more and more prominent. This requires reactors that can effectively treat high-concentration organic wastewater and at the same time efficiently and automatically produce biogas. The existing reactors ...
