The principle of ultrasonic cleaning machine is the recovery of some precious metal ions, such as silver ions, and others are some heavy metal ions, especially those that simply form environmental pollution, such as chromium, copper and other heavy metal ions. In fact, electrochemical treatment of sewage, especially the treatment of ions in sewage, has many advantages. First, the ions in sewage are reduced. Second, the metal recovered by electrochemical high-frequency rectifier can be recovered and reused, which not only effectively maintains the environment, but also promotes the recovery and use of waste.

电解电源使用于污水处理是有一些请求的，与电镀相同，污水处理技能中的电解电源通常是大电流低电压的直流电源或许单脉冲电源设备，其开展进程与电镀电源的开展进程相似。

There are some requirements for the use of electrolytic power supply in sewage treatment, which is the same as electroplating. The electrolytic power supply in sewage treatment skills is usually DC power supply with high current and low voltage or single pulse power supply equipment, and its development process is similar to that of electroplating power supply.

如今大多选用的是高频电解电源，其利于功率的再拓宽，减小空间占用，下降能耗，前进工作效率。别的十分重要的一点即是电解电源，尤其是用于污水处理的电解电源，电流承载才能是要远远大于电压的，也即是说大电流低电压，电压通常不会超越36V，正常情况下12V足够，而电流小则200A到300A，大则2000A到5000A甚更高，依污水成分以及处理流程而定。

Nowadays, most of them choose high-frequency electrolytic power supply, which is conducive to broadening the power, reducing space occupation, reducing energy consumption and advancing work efficiency. Another very important point is that the current carrying capacity of electrolytic power supply, especially for sewage treatment, is far greater than the voltage, that is, high current and low voltage, and the voltage usually does not exceed 36V. Under normal circumstances, 12V is sufficient, while the current is 200A to 300A, 2000a to 5000A or even higher, depending on the sewage composition and treatment process.

污水处理中的电化学处理办法如今现已日趋老练，许多类型的电化学处理污水技能现已十分完善，比方电镀厂废水的处理，废水电解收回贵金属等技能。

Electrochemical treatment methods in sewage treatment are becoming more and more sophisticated, and many types of electrochemical sewage treatment skills are now very perfect, such as electroplating plant wastewater treatment, wastewater electrolysis and recovery of precious metals.

别的电解电源在金属收回中的使用是与污水处理中金属收回的使用是差不多的，差异在于金属收回的废水中金属离子浓度较高，比方电镀厂、氧化处理等外表处理厂发生的废水，相对的减少了收回金属的本钱，而污水处理中的金属收回则大多是将污水中的金属离子浓度下降以到达污水排放规范，其金属收回本钱相对较高。

In addition, the use of electrolytic power supply in metal recovery is similar to that in sewage treatment. The difference is that the concentration of metal ions in the wastewater recovered from metal is high. For example, the wastewater from electroplating plants, oxidation treatment plants and other surface treatment plants relatively reduces the cost of metal recovery, The metal recovery in sewage treatment mostly reduces the metal ion concentration in sewage to meet the sewage discharge specification, and its metal recovery cost is relatively high.
