Nanping sanjin electronics co. LTD

Project introduction: sanjin electronics co., LTD. L production process using chemical nickel plating and electrolytic nickel plating process, produces the wastewater containing nickel, nickel ion is the first in the national wastewater discharge standard random discharge of pollutants is forbidden, because it can accumulate in environmental and animal and plant body, cause long-term adverse effects on human health, so the waste water containing such substances, divisions and discharge way, also regardless of the function of receiving waters and categories, the maximum allowable emission concentration Ni2 + < 1.0 mg/L.

Treatment measures: due to the low concentration of heavy metal ions contained in the wastewater, it has no recovery value. Generally, the selection of treatment methods does not carry out recovery treatment such as electrolysis, ion exchange and other treatment methods, but adopts chemical neutralization, flocculation and precipitation methods with low investment and mature technology.

Treatment effect: the treated water nickel content ≤1mg/l, discharge standards.
