Embodiment Construction

[0054] Please refer to Figure 1 to Figure 7As shown, it shows the specific structure of the electrocoagulation wastewater treatment device 10 of the preferred embodiment of the present invention. The electrocoagulation wastewater treatment device 10 is composed of multiple sections of pipelines 11 circuitously connected in series. Water inlet 12 is arranged, and water inlet valve 13 is installed at this water inlet 12 places. A water outlet 14 is provided on the final pipeline 112, and a pressurizing valve 15 is installed at the water outlet 14. A detection valve 16 is installed at the joint 114 of any section of pipeline 113 in the middle and its upper section of pipeline, and a dosing valve 17 is installed at the joint 114 of its next section of pipeline.

[0055] like Figure 2 to Figure 5 As shown, each section of tubing 11 includes an anode 115 and a cathode 116 for electrocatalysis. The cathode 116 is tubular, forming a lumen 1161 inside the cathode 116; the anode 11...

Abstract

The invention discloses an electrocoagulation waste water treatment device. A pipeline is multisegmental, a detection value is arranged on the upstream end of each segment of pipeline, a dosing valve is arranged on the downstream end of each segment of pipeline so as to realize the fact that any pipeline segment is filled with medicaments, different medicaments can be added in different pipeline segments and different flow ways so as to meet the treatment demand; secondly, an anode and a cathode are arranged on each segment of pipeline of the electrocoagulation waste water treatment device, the anode and the cathode exist in a pipeline, an anti-leakage rubber tube sleeves the outsides of the pipelines so as to provide a closed reaction space, the generated harmful gas cannot be dispersed and is easily controlled, the reaction is complete, and the combination is convenient; furthermore, a pressurizing valve is arranged at a water outlet of the electrocoagulation waste water treatment device to be matched with the airtight environment in each segment of pipeline, so that the pressurization on the gas can be conducted, the solubility of the gas is higher, and the treatment effect is better; in conclusion, by adopting the electrocoagulation waste water treatment device, the sewage treatment effect can be greatly improved, and the reaction can be shortened.

Description

technical field [0001] The invention relates to the technology in the field of wastewater treatment, in particular to a new application of a tubular electrochemical device in wastewater treatment. Background technique [0002] At present, there are the following centralized traditional methods for the pre-treatment of electroplating heavy metal wastewater before reuse: [0003] 1. Precipitation method: that is, by adding chemicals to form metal oxide precipitation or metal oxide co-precipitation on the generated precipitate, so as to achieve the purpose of removing heavy metal ions. To a certain extent, this method has disadvantages such as difficulty in reaching the standard after treatment, slow sedimentation of sludge and difficulty in dehydration. [0004] 2. Adsorption method: through the exchange of metal ions with ions or functional groups in the adsorbent, they are adsorbed on the adsorbent and removed. The shortcomings of this method are: some adsorbents have low ...
