The principle of ultrasonic cleaning equipment 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.

電解電源使用于污水處理是有一些請求的，與電鍍相同，污水處理技能中的電解電源通常是大電流低電壓的直流電源或許單脈沖電源設(shè)備，其開展進(jìn)程與電鍍電源的開展進(jìn)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.

如今大多選用的是高頻電解電源，其利于功率的再拓寬，減小空間占用，下降能耗，前進(jìn)工作效率。別的十分重要的一點(diǎn)即是電解電源，尤其是用于污水處理的電解電源，電流承載才能是要遠(yuǎn)遠(yuǎn)大于電壓的，也即是說大電流低電壓，電壓通常不會超越36V，正常情況下12V足夠，而電流小則200A到300A，大則2000A到5000A甚至更高，依污水成分以及處理流程而定。

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.

污水處理中的電化學(xué)處理辦法如今現(xiàn)已日趨老練，許多類型的電化學(xué)處理污水技能現(xiàn)已十分完善，比方電鍍廠廢水的處理，廢水電解收回貴金屬等技能。

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.

別的電解電源在金屬收回中的使用是與污水處理中金屬收回的使用是差不多的，差異在于金屬收回的廢水中金屬離子濃度較高，比方電鍍廠、氧化處理等外表處理廠發(fā)生的廢水，相對的減少了收回金屬的本錢，而污水處理中的金屬收回則大多是將污水中的金屬離子濃度下降以到達(dá)污水排放規(guī)范，其金屬收回本錢相對較高。

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.
