When it comes to micro-electrolytic fillers, everyone must be very familiar with it. It is a common sewage treatment material and is widely used by many companies. However, some problems will inevitably occur during use, so let's introduce some common problems and solutions that cause the reduction of the treatment effect in the iron-carbon micro-electrolysis water treatment process.

1. Fluctuation of water quality, and then determine the best PH value and residence time according to different water quality

2, PH value adjustment, adjust the appropriate PH value, because the PH value difference of 0.5 removal effect will be very different

3. The residence time, the length of the residence time, is also the length of the redox action time. The longer the residence time, the more thorough the reaction, but too long will not work, so you should choose the best stay time.

4. Aeration amount, aeration is beneficial to the oxidation of certain substances and to the removal of surface passivation film. However, excessive aeration will affect the contact time between water and filler, which will reduce the removal rate. The best value should be taken or intermittent aeration should be adopted.

5. Flocculation and sedimentation, the flocculation and precipitation of micro-electrolysis effluent is not good, not only will ferrous ions react to COD, but also cause a series of problems in subsequent treatment.

6. Passivation, some suspended substances are deposited on the surface of the filler to form a dense passivation film, which reduces the contact area of the filler and water, shortens the reaction time, and reduces the treatment effect. You can increase the amount of aeration to flush the filler. Then, the acidic wastewater is used to activate the filler to restore its activity.
