Embodiment Construction

[0028] Please check figure 1 , an electrocoagulation device for sewage treatment, which includes a container 100, an electrode device 200 and a marking assembly 300.

[0029] The container 100 is used to hold sewage liquid, and it includes a shell 110 and a cover body 120 that can be detachably connected to the shell 110 . An insulating inner wall 111 is fixed inside the housing 110 . The housing 110 is made of anti-aging and corrosion-resistant materials. In this embodiment, steel, stainless steel, glass fiber reinforced plastic or plastic can be used. The shape of the shell 110 is not limited, for example, it can be prism, cylinder, inverted triangular funnel, truncated prism, or pyramid. Proportional reduction, similar to cone or truncated cone. A support frame 130 is fixed above the center of the bottom of the container 110 , so that the bottom of the container 110 forms a slag funnel 170 .

[0030] In this embodiment, the container 100 defines a water inlet at the bot...

Abstract

The invention discloses an electrocoagulation device and method for sewage treatment. The electrocoagulation device comprises a container and an electrode assembly, wherein the container is used for containing sewage liquid; and the electrode assembly is arranged in the container. The method is as follows: separating out OH ion and electrode ion by electrolysis because the electrode assembly obtains electrical energy; combining the OH ion and the electrode ion to form flocculant; and carrying out flocculation reaction on the flocculant and the sewage liquid so that harmful substances in the sewage liquid are coagulated to form floccus precipitate for later treatment. The method has the advantages that the OH ion and electrode ion are separated out by electrolysis and combined to generate the flocculant, thus additional flocculant dose not need to be directly added.

Description

technical field [0001] The invention relates to an electrocoagulation device and method for sewage treatment. Background technique [0002] The method of treating sewage with chemical flocculants is widely used. It is a method of separating harmful substances in sewage through the mechanism of flocculation of harmful substances in sewage through the mixing and stirring of chemical flocculants and sewage. This method has the following disadvantages: 1. The cost of the flocculant itself is high and the amount of addition is large, so that the cost of treating sewage with this method remains high; bring inconvenience. Contents of the invention [0003] The invention provides an electrocoagulation device and method for sewage treatment, which overcomes the shortcomings of the method for treating sewage with chemical flocculants in the background technology. [0004] One of the adopted technical schemes that the present invention solves its technical problem is: [0005] An ...
