Embodiment 1

[0024] This embodiment provides a performance testing method for electrocoagulation water treatment devices, which is used to test the performance of electrocoagulation water treatment devices on the market, and then realize the classification of product performance of electrocoagulation water treatment devices, and finally evaluate the performance of electrocoagulation water treatment devices. The production and application of flocculation water treatment devices play a guiding role.

[0025] Such as figure 1 Shown, the performance evaluation method of electrocoagulation water treatment device of the present invention, comprises the following steps:

[0026] S10, determining the performance evaluation index of the electrocoagulation water treatment device;

[0027] In an embodiment of the present invention, the performance evaluation indicators of the electrocoagulation water treatment device include current efficiency, current efficiency drop rate, liquid age distribution f...

Embodiment 2

[0064] An enterprise evaluates the newly purchased electrocoagulation water treatment device, which is used to treat the enterprise's high-suspended solids wastewater, with a scale of 500 tons / day.

[0065] According to the evaluation method of the present invention, the evaluation calculation score is 92, the evaluation result is "good", and the pollutant treatment effect reaches the expected effect.

Embodiment 3

[0067] A manufacturer evaluated the five-year-used electrocoagulation water treatment device during the maintenance process. The device is used to treat wastewater from a printing and dyeing enterprise, with a scale of 1200 tons / day.

[0068] According to the evaluation method of the present invention, the evaluation calculation score is 52, the evaluation result is "poor", and the treatment effect is only 50% of the design value. Through further analysis of the single basic performance evaluation index, it is found that the current efficiency, current efficiency decline rate and resistance The scores of the three indicators of corrosion performance were too low. The electro-flocculation water treatment device was replaced with electrodes and internal circuits, and the treatment effect was restored. The electro-flocculation water treatment device was evaluated again, and the evaluation result was "good", and the pollutant treatment The effect meets expectations.

Abstract

The invention discloses a performance evaluation method of an electric flocculation water treatment device. The method comprises the following steps: S10, determining performance evaluation indexes ofthe electric flocculation water treatment device; S20, determining the weight of the performance evaluation index of the electric flocculation water treatment device; S30, detecting performance evaluation indexes of the electric flocculation water treatment device; and S40, performing performance score calculation on the electric flocculation water treatment device. According to the performance evaluation method of the electric flocculation water treatment device, all the performance evaluation indexes of the electric flocculation water treatment device are scored and are weighted, so that the performance of different electric flocculation water treatment devices is objectively evaluated, each single score can be analyzed to diagnose product defects, possible problems in use are identified, and the water treatment effect of the electric flocculation water treatment device is favorably improved.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a performance evaluation method of an electrocoagulation water treatment device. Background technique [0002] In the prior art, the integration of water treatment devices, especially the integration of electrocoagulation water treatment devices has become a trend. The electrocoagulation method is to use aluminum, iron and other metals as the anode alone under the action of an external electric field. Under the action of the current, the anode is dissolved to generate ions, and the complexes are generated by hydrolysis to flocculate the wastewater, thereby removing pollutants in the wastewater. The water purification technology removed has the characteristics of convenient operation and management and high treatment efficiency, while the integrated electrocoagulation water treatment device treats wastewater by electrocoagulation method, which has the advantages of sm...
