Anaerobic reactor for processing high organic concentration and high solid content waste water

Abstract

The invention discloses an anaerobic reactor for processing wastewater with high concentration of organic matters and high solid contents, and the anaerobic reactor is applicable to the anaerobic digestion treatment of the wastewater with high concentration of organic matters and high solid contents, such as wastewater in a livestock breeding farm, residual sludge in a sewage disposal plant, etc. A main body (1) of the reactor is two concentric cylinders while the middle cylinder is a high solid reaction zone (5) and the outer ring is a baffling reaction zone (25). The high solid reaction zone (5) and the baffling reaction zone (25) share a part of a tank wall, namely a tank wall (4) of the high solid reaction zone. The high solid reaction zone (5) is a cylinder and the lower part of the high solid reaction zone is provided with a water inlet pipe (2) and a water distribution system (3) while water current flows in the form of upward current; the bottom part of the high solid reaction zone (5) is provided with a sludge sedimentation zone (6) taking the shape of a cone and an intermittent sludge discharging pipe (7); the edge around the upper part of the high solid reaction zone (5) is provided with a slag trap (8) and a water collecting tank (9) while the middle of the upper part is provided with a gas collection chamber (10) and the top is provided with a sealing cover (11) and a gas collection pipe (12).

Description

technical field [0001] The invention is an anaerobic reactor suitable for anaerobic digestion treatment of waste water from poultry farms, excess sludge from sewage treatment plants and the like containing high organic matter concentration and high solid content. It belongs to the field of environmental engineering technology. Background technique [0002] At present, with the increase of population and the improvement of environmental protection requirements, the number of urban sewage treatment plants continues to increase, resulting in an increase in the amount of residual sludge in sewage treatment plants; the continuous development of the livestock breeding industry has led to an increase in the amount of wastewater from livestock breeding Increase. Excess sludge and poultry farm wastewater have high organic concentration and solid content. Using anaerobic process to treat them can not only reduce their volume, but also recover biomass energy and effectively reduce pol...
