Abstract

The invention discloses a nickel-containing wastewater reduction system, which includes an evaporation tank, a condensation tank and a buffer pool. The evaporation tank is fixed at the left position in the middle of the base, and a second stirring shaft is vertically installed inside the evaporation tank. An oil bath heating pipe is arranged on the periphery of the evaporation tank where the second stirring shaft is located, and an oil bath heating tank is installed on the left side of the base where the evaporation tank is located, and the oil bath heating tube of the first stirring shaft is A temperature sensor is installed on the inner bottom of the tank, a waste water inlet pipe is arranged on the front surface of the evaporation tank, a condensation tank is installed on the right side of the base where the evaporation tank is located, and a condensation coil is arranged inside the condensation tank, so A buffer pool is installed on the right side of the base where the condensation tank is located, and a clean water outlet is provided at the bottom of the right side of the buffer pool. The invention solves the problem that the waste water electrolysis nickel discharge is not up to the standard by setting an evaporation tank, a condensation tank and a buffer pool.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a nickel-containing wastewater reduction system. Background technique [0002] In industrial production, electrolysis is used to extract nickel from nickel-containing wastewater. During electrolysis, as the concentration of nickel ions in the solution decreases, nickel ions cannot be completely electrolytically deposited, and the solution after electrolysis still contains a certain concentration of nickel ions, which is difficult. To meet the discharge requirements, the traditional method of adding alkali to the solution to adjust the pH and using the recapture agent M1 for precipitation treatment is cumbersome and requires strict control of the pH value in the electrolytic cell. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the invention provides a nickel-containing waste water reduction sys...
