Abstract

The invention relates to the field of water feed treatment and particularly relates to an electrochemical reaction tank for treating algae-containing water. In the electrochemical reaction tank, a water inlet is arranged at the center or a position which enables a water flowing channel to be as long as possible, wherein a water outlet gate is arranged on one side wall of the reaction tank, and electrode separation plates are vertically arranged in the reaction tank and are insulated from each other, so that a revolving or a reciprocating flowing channel is formed in the reaction tank. Cathodeplate groups or anode plate groups are installed on the electrode separation plates which are parallel with each other, wherein the polarities of the plates on the adjacent parallel sections are different, so that an electric field is formed between the adjacent parallel sections; a travelling scraping machine and a travelling scraping machine rail are arranged on the top of the reaction tank, wherein the travelling scraping machine rail is in parallel with the side wall on which the water outlet gate is arranged. The reaction tank can be constructed by modifying a conventional flocculation tank, and allows a water plant to rapidly respond to and deal with sudden burst of algae pollution, thus achieving treatment on the algae-containing water.

Description

technical field [0001] The invention relates to the field of water supply treatment, in particular to an electrochemical reaction tank for treating algae-containing water. Background technique [0002] Algae outbreaks in slightly polluted water bodies not only affect the safety of the water environment, but also seriously threaten the safety of water treatment. Traditional algae removal structures in waterworks include microfilters, air flotation tanks and floating sinks. However, because algae blooms only occur when environmental conditions are suitable, many water plants do not have separate algae removal structures such as microfilters and air flotation tanks. During the algae outbreak, the water plant mainly uses methods such as pre-oxidation, enhanced coagulation, and increasing the frequency of backwashing of the filter. These methods have limited treatment effects and will also increase the risk of secondary pollution of the water body. The floating-sinking tank use...
