The invention discloses a hydraulic anaerobic reaction system and a control method thereof. The system comprises a feeding unit, an anaerobic reaction unit, a sludge-water separation unit, a sludge return unit and a biogas discharge unit, wherein the feeding unit is connected with the anaerobic reaction unit, the sludge-water separation unit is connected with the anaerobic reaction unit, the receiving end of the sludge return unit is connected with the sludge-water separation unit, the output end of the sludge return unit is connected with the anaerobic reaction unit, and the biogas dischargeunit is connected with the anaerobic reaction unit and the sludge-water separation unit. According to the system and the control method, the anaerobic sludge can be intercepted in the system on the premise of avoiding blockage, the retention amount of the anaerobic sludge in the system is maintained, and high volume load and high gas yield are realized.
Description
technical field [0001] The invention relates to the field of environmental protection, in particular to a hydraulic anaerobic reaction system and a control method thereof. Background technique [0002] The anaerobic reaction system in the prior art is mainly divided into two categories, the fully mixed anaerobic reactor and the upflow anaerobic sludge bed; both have incompatibility, and the fully mixed anaerobic reactor is used, Anaerobic sludge is easy to be lost with the discharge, which may easily cause excessive organic load and acidification of the system; using an upflow anaerobic sludge bed, the concentration of anaerobic sludge will be unevenly distributed, gradually decreasing from bottom to top, and scum will accumulate The shell is easy to block the upper three-phase separator, making it difficult to separate biogas, water and anaerobic sludge, and it is difficult to operate stably. The anaerobic reaction system according to the embodiment of the present inventio...
