Project Overview: Meirongxiang Microelectronics Technology (limited) company of its products mainly for the integrated circuit package containing the plating process, the use of non-cyanide electroplating, cyanide emissions. The wastewater comes mainly from the surface treatment process before the surface treatment need to repeatedly washed with water, to produce large amounts of acid, alkali, oils, surface active agents, also produce metal ions in the process. Preparation of pure water system in reproduction, occasionally discharge a small amount of acid-base backwash water in the production process are also part of the mother liquor after multiple uses of the need to replace emission (such as stripping the developing waste, etc.). Waste and waste water must be harnessed before being discharged.

Design: the production of treated wastewater discharge standards; waste reuse after treatment.

Design size: 1,050 tons / day

Water quality standards: GB8978-1996 two emission standards
