Abstract

Disclosed is a chemical nickel waste liquid integrated processing system. The chemical nickel waste liquid integrated processing system is characterized in that solid-liquid separation can be performed on chemical nickel waste liquid, and the system comprises an evaporation device, a cooling tower, a conduction oil circulating device, an electric control cabinet and an automatic control unit; the evaporation device comprises a steam-liquid separator, a feeding electric valve, an emptying valve, a heating chamber, a condenser, a water storage tank and a vacuum pump; the water storage tank is composed of a first tank body and a second tank body. The chemical nickel waste liquid integrated processing system is high in integration degree, small in occupied area and capable of safely, stably and effectively removing phosphorus, nickel and COD in chemical nickel waste liquid, no secondary pollution is generated, and the processed chemical nickel concentrated solution has the recycling value.

Description

technical field [0001] The invention relates to the field of industrial waste liquid treatment, in particular to an integrated chemical nickel waste liquid treatment system, which is especially used for treating chemical nickel waste liquid produced in circuit board processing industry and electroplating industry. Background technique [0002] Electroless nickel surface treatment is widely used in circuit board industry and electroplating industry. In the production process, because the chemical nickel stock solution has been left for a long time and cannot meet the production requirements due to chemical reactions, it is discarded (commonly known as aging). . The concentration of pollutants in these two waste liquids is high, the risk factor is high, and the treatment is difficult. These two waste liquids all contain a certain amount of nickel, but the nickel content is low and has no resource utilization value; the main components of the chemical nickel waste liquid are ...
