Abstract

The invention provides a horizontal anaerobic digestion reaction device, and belongs to the field of solid waste treatment. The system device is used for artificially creating nutrition and condition essential to anaerobes, so that anaerobes having high concentration are accumulated in a reactor, and complete an organic anaerobic metabolizing process through the living activities of the anaerobes. The device comprises a reactor main body having a horizontal structure, wherein the reactor main body is provided with an inner tank and an outer jacket; the inner tank has a feed opening and a discharge opening; screw propellers with forward and reverse augers are arranged at the lower part of the reactor main body; a stirrer is arranged at the upper part of the reactor main body and is provided with a concentric transmission shaft and multiple groups of hollow blades connected to the transmission shaft; rake teeth are arranged on two sides of each blade, and rake teeth of adjacent blades are staggered; a baffle and a deflector are arranged in each blade; and the inner cavity and the outer cavity of the concentric transmission shaft are respectively connected with water inlet and outlet pipes of each blade.

Description

technical field [0001] The invention belongs to the field of solid waste treatment and relates to a horizontal anaerobic digestion reaction device used in anaerobic digestion reaction experiments. Background technique [0002] Anaerobic digestion is a complex chain reaction process consisting of four processes: hydrolysis, acidification, acetogenic / dehydrogenation, and methane production. Each degradation step is carried out by different bacterial groups that are interrelated to some extent and have different environmental requirements. First of all, the polymeric substances or monomers in the organic matter are firstly utilized by the hydrolytic fermentation bacteria to produce acetic acid, hydrogen, propionic acid, butyric acid and other volatile fatty acids. The accumulation of hydrogen will inhibit the activity of acetic acid bacteria, so maintaining a low hydrogen partial pressure is very important for hydrogen-producing acetogenic bacteria, and the entire anaerobic di...
