Problems solved by technology
[0003] The purpose of the present invention is to solve the problem of low efficiency and complex equipment by completely separating solid and liquid wastes and then treating them separately when treating organic waste water with high solid content
A further object of the present invention is to provide an upflow anaerobic bioreactor for treating organic wastewater with a high solid content in order to solve the problem that the conventional anaerobic bioreactor is clogged and the scum is too much in order to solve the problem that the solid content in the organic wastewater treatment is too high The device, specifically, is a method and device for improving the ability of an upflow anaerobic sludge bed to treat organic wastewater with high solid content by utilizing the hydraulic impact of the outer tank and the return flow of gas to form a fluidized bed in the inner tank

Abstract
The invention discloses an anaerobic bioreactor for treating organic waste water with high solid content and an operating method of the anaerobic bioreactor. The anaerobic bioreactor comprises an outer kettle liquid reactor and an inner kettle solid reactor arranged inside the outer kettle liquid reactor, wherein the outer kettle liquid reactor is additionally provided with a gas reflux circulation system, and the gas reflux circulation system is directly introduced to the inner kettle solid reactor so as to achieve the purpose of pneumatically stirring a solid. Compared with the prior art, the anaerobic bioreactor has the following advantages that the inner solid waste reactor and the outer liquid reactor are arranged in a combination way, the whole device is compact in structure, the solid waste is digested in the inner reactor, pipeline blockage is effectively avoided, and the substances in the inner solid reactor are enabled to be in a fluidized state under the double stirring effects of gas reflux circulation and water impact, so that the separation of soluble substances in the solid is effectively promoted.
Description
technical field [0001] The invention belongs to the field of environmental protection, and more specifically relates to an anaerobic digestion reaction device for organic waste water with high solid content and an operation method thereof. Background technique [0002] Anaerobic biodigestion is a common method for treating high-concentration organic wastewater. At present, common anaerobic bioreactors mainly include first-generation reactors represented by anaerobic digestion tanks and anaerobic contact tanks; anaerobic filters, The second-generation reactor represented by upflow anaerobic sludge bed and fluidized bed; and the third-generation reactor represented by anaerobic granular sludge bed, anaerobic internal circulation and anaerobic baffle type. These anaerobic bioreactors have certain effects in improving the living conditions of anaerobic sludge and increasing the removal rate of chemical oxygen demand in sewage. It is especially suitable for the treatment of orga...
