Abstract
Description
Technical Field

[0002] Electrolytic spray wastewater refers to the wastewater generated by the spray water used in the electrolysis process. In the electrolysis process, water is usually used as a solvent or carrier to transfer electrolytes or cool electrodes. These spray waters may be contaminated during the contact process and contain various organic and inorganic substances, such as metal ions, salts, acids and alkalis. It is very important to maintain a constant pH value in the treatment of electrolytic spray wastewater, because changes in pH will affect the solubility and precipitation of various chemical substances in the wastewater, thereby affecting the effect of wastewater treatment.
[0003] However, the electrolytic spray wastewater in the prior art is mostly treated by neutralization, by adding an appropriate amount of neutralizer to the acidic or alkaline wastewater to react with the acidic or alkaline components in the wastewater, thereby adjusting the pH value of the wastewater to a target range. However, the low temperature of the wastewater will greatly reduce the reaction effect, and the use cost will also increase if a heater is used to heat the wastewater. For this reason, we provide a constant pH treatment device for electrolytic spray wastewater to solve the above problems. Utility Model Content
