Abstract

The present invention discloses a kind of anaerobic mud bed reactor for treating organic waste water. The anaerobic mud bed reactor has rectangular or circular horizontal cross section, is provided with inflow devices homogeneously distributed in the inflow end and outflow device in the far end to the inflow end, and may form the reasonable distribution of type-A mud grains in the front part and type-B and type-C mud grains in the back part. The present invention has organic waste water treating capacity higher than UASB reactor, COD volume load in unit reactor as high as several kg or even decades kg, and lower investment.

Description

[0001] (This application is a divisional application of the application number 200310110817.6, the application date is October 31, 2003, and the invention name is the treatment method of organic wastewater and its anaerobic sludge bed reactor) technical field [0002] The invention relates to an anaerobic sludge bed reactor for organic waste water treatment, in particular to an anaerobic sludge bed reactor for brewing, food, papermaking, chemical industry, oil pressing and other waste water treatment. Background technique [0003] The anaerobic sludge bed reactor for organic wastewater treatment is mainly used to decompose the organic pollutants contained in the wastewater through the action of microorganisms to form biogas, sludge, etc., so as to achieve the purpose of purification. At present, the anaerobic reactors used in organic wastewater treatment mainly include ordinary anaerobic digesters, anaerobic contact processes, anaerobic filter beds (AF), anaerobic fluidized b...
