Abstract

The present invention discloses one kind of circular granular sludge reactor with great load capacity, stable running, simple structure and other advantages. The circular granular sludge reactor has the structure including several anaerobic reactor tanks, each of which has a water distributor connected to the water inlet pipe and a sludge exhausting unit in the lower part, at least one layer of triphase separator with top vapor-water separator connected to the inner circulating pipe and methane lifting unit, an outer return pipe connected to the water inlet pipe, an outer circulating unit and a granular sludge circulating unit.

Description

technical field [0001] The invention relates to an anaerobic reactor for water treatment, in particular to a circulating granular sludge reactor relying on the joint action of internal circulation and external circulation. Background technique [0002] With the rapid development of industry and the continuous increase of population, the problems of energy, resources and environment have become increasingly serious. In the past 30 years, the shortage of energy has become more prominent. Using traditional aerobic biological treatment methods to treat wastewater consumes a lot of energy. The energy consumption for wastewater treatment in developed countries has accounted for about 1% of the country's total electricity consumption. The essence of aerobic biological treatment of wastewater is a technical measure to improve the quality of wastewater to meet the requirements of water environment quality by using the consumption of electric energy. Therefore, aerobic biological tre...
