Abstract

The invention belongs to the technical field of sludge digestion treatment, and discloses a novel sludge digestion reactor. The novel sludge digestion reactor comprises a sludge digestion tank cover mechanism and a sludge digestion tank body mechanism; the sludge digestion tank cover mechanism comprises a stirring motor, a sludge digestion tank cover, a sludge stirring mechanism and a sludge ultrasonic disintegration device; the sludge digestion tank mechanism comprises a sludge inlet, a discharge port and a sampling port; the sludge stirring mechanism comprises a stirring rod fixer, a stirring rod, foaming blades and stirring blades; the sludge ultrasonic disintegration device comprises an ultrasonic transducer and a strip-shaped flat ultrasonic probe. The sludge digestion reactor provided by the invention can effectively improve the sludge digestion rate and shorten the sludge digestion period.

Description

technical field [0001] The invention relates to the technical field of sludge digestion treatment. Background technique [0002] Anaerobic digestion of sludge is a sludge treatment technology that uses facultative and anaerobic bacteria to convert biodegradable organic matter in sludge into methane and carbon dioxide. Since this digestion technology produces valuable biogas while stabilizing the organic matter, it is considered to be one of the most cost-effective sludge treatment technologies. Although sludge anaerobic digestion is an important part of modern sewage treatment plants, it still has the problems of slow sludge digestion rate and long digestion cycle. Anaerobic digestion is divided into four stages: hydrolysis stage, acidification stage, hydrogen and acetic acid stage, and methane stage. Among them, the hydrolysis stage is the rate-limiting stage of the entire digestion process. This is due to the slow rate of dissolution of particulate matter and the rate a...
