Membrane chemical reactor, water treatment system and water treatment method

Abstract

The invention relates to the technical field of water treatment, in particular to a membrane chemical reactor, a water treatment system and a water treatment method. The membrane chemical reactor comprises a main body, a water guide assembly and a membrane assembly, wherein the water guide assembly comprises a plurality of first water guide plates and a plurality of second water guide plates, and the plurality of first water guide plates and the plurality of second water guide plates are sequentially accommodated in a membrane tank at intervals, are arranged in a staggered manner and jointly form a snakelike first flow guide channel; the membrane assembly comprises a membrane box, a plurality of first membranes and a plurality of second membranes; the plurality of first membranes and the plurality of second membranes are sequentially accommodated in the membranes tank at intervals, are arranged in a staggered manner, and jointly form a snakelike second flow guide channel; and two ends of the first flow guide channel are respectively communicated with a water inlet and the second flow guide channel, and the membrane tank is communicated with the water outlet. Therefore, by means of the arrangement mode, the water flow state can be improved, the good pollution control effect is achieved, the chemical cleaning time is prolonged, and then stable and efficient operation can be achieved.

Description

technical field [0001] The present application relates to the technical field of water treatment, in particular to a membrane chemical reactor, a water treatment system and a water treatment method. Background technique [0002] In water treatment, the chemical method is a method of changing the chemical or physical properties of pollutants in sewage through chemical reactions, making them change from a dissolved, colloidal or suspended state to a precipitated or floating state and then removed from the water. [0003] The existing process often adopts "chemical reaction-precipitation-multi-media filtration". However, such a combination often occupies a large area, consumes a lot of chemicals and energy, and cannot meet the urgent needs of project upgrades and capacity expansion. [0004] Membrane filtration is a high-efficiency filtration technology, in which ultrafiltration / microfiltration membrane can separate suspended solids, bacteria, particulate matter and water due t...

Problems solved by technology

However, the traditional ultrafiltration has high requirements on the turbidity of the incoming water, which does not exceed 50NTU. When the turbidity of the incoming water is high, the anti-pollution effect is limited and cannot operate stably.
