(1)镀件清洗水；
(1) cleaning water for plated parts;
(2)废电镀液；
(2) waste plating solution;
(3)其他废水，包括冲刷车间地面，刷洗极板洗水，通风设备冷凝水，以及由于镀槽渗漏或操作管理不当造成的 “跑、冒、滴、漏”的各种槽液和排水；
(3) Other wastewater, including washing the floor of the workshop, washing the plates, condensate of ventilation equipment, as well as the "run, run, drop, leak" caused by the leakage of plating trough or improper operation and management of various trough fluids and drainage;
(4)设备冷却水，冷却水在使用过程中除温度升高以外，未受到污染。电镀废水的水质、水量与电镀生产的工艺条件、生产负荷、操作管理与用水方式等因素有关。电镀废水的水质复杂，成分不易控制，其中含有铬、镉、镍、铜、锌、金、银等重金属离子和氰化物等，有些属于致癌、致畸、致突变的剧毒物质。
(4) the cooling water of the equipment is not polluted unless the temperature rises during the use of the cooling water. The quality and quantity of electroplating wastewater are related to the technological conditions, production load, operation and management, and water consumption mode of electroplating production. The water quality of electroplating wastewater is complex and its composition is not easy to control. It contains heavy metal ions such as chromium, cadmium, nickel, copper, zinc, gold, silver and cyanide. Some of them are carcinogenic, teratogenic and mutagenic toxic substances.
