A kind of flue gas desulfurization wastewater treatment method

Abstract

The invention discloses a flue gas desulfurization waste water treatment method which adopts wastewater treatment equipment. The wastewater treatment equipment comprises a framework 129 and closed treatment plates 100, wherein the closed treatment plates 100 are arranged at two ends of the framework 129 symmetrically; a separation cavity 126 which passes through left and right is formed inside theframework 129; a first cavity 111 is formed in the bottom of the separation cavity 126; a first guide chute 103 is formed in the inner wall of the left end of the first cavity 111 in a communicated manner; a second guide chute 116 is formed in the inner wall of the right end of the first cavity 111 in the communicated manner; treatment cavities 130 which are opened towards the separation cavity 126 are formed in the closed treatment plates 100; storage grooves 105 are formed in the bottoms of the treatment cavities in the communicated manner; a first rotating shaft 119 which extends up and down is rotationally connected in match between the separation cavity 126 and the first cavity 111; the extended tail end of the top of the first rotating shaft 119 extends into the separation cavity 126; a rotating disc 120 is arranged at the tail end.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a method for treating flue gas desulfurization wastewater. Background technique [0002] With the development of science and technology and the progress of society, the country has been promoting the development of high technology. In the field of wastewater treatment technology, there has always been a relatively difficult technical problem. Among them, the wastewater after flue gas desulfurization treatment in limestone-gypsum slurry includes Two parts, one is the gypsum slurry after the reaction, and the other is the waste water formed by flushing equipment. There are a large amount of suspended solids, heavy metals and acid radical ions in this waste water, so it is a big problem to effectively treat the pollutants in the waste water, and the existing The general equipment is large in size, each process works separately, and the processing environment is not airtight, whic...

[0002] With the development of science and technology and the progress of society, the country has been promoting the development of high technology. In the field of wastewater treatment technology, there has always been a relatively difficult technical problem. Among them, the wastewater after flue gas desulfurization treatment in limestone-gypsum slurry includes Two parts, one is the gypsum slurry after the reaction, and the other is the waste water formed by flushing equipment. There are a large amount of suspended solids, heavy metals and acid radical ions in this waste water, so it is a big problem to effectively treat the pollutants in the waste water, and the existing The general equipment is large in size, each process works separately, and the processing environment is not airtight, which not only has low processing efficiency, but also pollutes the environment. At the same time, the device is not easy to clean after long-term use. This device effectively solves this problem.
