Abstract

The invention relates to a double-rotational-flow water distributor and an anaerobic reactor, the double-rotational-flow water distributor comprises an inner rotational-flow water distribution structure and an outer rotational-flow water distribution structure which are fixed at the bottom of an inner cavity of the anaerobic reactor, and the inner rotational-flow water distribution structure and the outer rotational-flow water distribution structure are not connected; and the inner rotational flow water distribution structure, the outer rotational flow water distribution structure and the bottom surface of the anaerobic reactor between the inner rotational flow water distribution structure and the outer rotational flow water distribution structure jointly form a sludge collecting ring conefor collecting anaerobic sludge. Two-way rotational flow formed by the double-rotational-flow water distribution structure is matched with scattered water flow formed by the downcomer water distribution structure, the three directions are strongly staggered, the mixing efficiency of sewage and anaerobic sludge is improved, the mass transfer efficiency is improved, and the reaction efficiency of the reactor is improved.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a double-swirl water distributor and an anaerobic reactor. Background technique [0002] In the field of sewage treatment, compared with aerobic biological treatment, anaerobic biological treatment has the following advantages: 1. It has a wide range of applications and can treat various types of wastewater with high, medium and low concentrations. 2. The energy demand is small and a large amount of energy can be generated. 3. High organic load. 4. The amount of residual sludge is small, and the anaerobic granular sludge produced can be used as a special strain, which has commercial value. 5. The demand for nutrients is small. 6. Strong impact load resistance. [0003] In the anaerobic reactor, the sewage is mixed with the anaerobic sludge through the water distribution structure, and the anaerobic sludge degrades the organic matter in the sewage and converts it into biogas.
