Intelligent purification device for nickel plating wastewater

Abstract

The invention belongs to the technical field of wastewater treatment, and particularly relates to an intelligent purification device for nickel plating wastewater. The intelligent purification devicecomprises a box body and a controller; the controller is used for controlling the device to operate automatically, and the controller is fixedly arranged on the side wall of the box body; a water inlet pipe is arranged at the top of the box body, a water outlet pipe is arranged at the bottom of the box body, and a waste water treatment module is arranged in the box body; the water inlet pipe is provided with a detection module, a sulfuric acid lead-in pipe is connected to the water inlet pipe, and a first magnet is arranged at an end of the water inlet pipe; the detection module is used for detecting whether the pH value of wastewater in the water inlet pipe meets the requirements; the sulfuric acid leading-in pipe is connected with a fresh water leading-in pipe; and the wastewater treatment module is used for purifying the wastewater. The intelligent purification device is simple in structure, and operation is convenient; the wastewater can be continuously purified through cooperationof the wastewater treatment module and a purification unit, and treatment efficiency is not affected while sufficient treatment time of the wastewater is ensured; and through two-time purification, the wastewater is completely purified, and water pollution is avoided.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, in particular to an intelligent purification device for nickel-plating wastewater. Background technique [0002] The nickel-containing wastewater is treated centrally after discharge. In the process, chemicals, acids, and alkalis need to be added to adjust to an appropriate pH value, and then flocculants are added to flocculate and settle nickel heavy metals. Nickel-containing sludge is hazardous waste and must be handed over to qualified professionals. Company processing. The water can only be discharged after biochemical treatment. Among them, adjusting the pH value is the key. Repeated dosing often causes waste due to different reaction rates of the pH meter, which also increases the processing cost and affects the processing efficiency. . [0003] There are also some technical solutions for the treatment of nickel-containing wastewater in the prior art. For example, a Chinese ...

Problems solved by technology

However, this technical solution cannot achieve continuous continuous purification without affecting the purification efficiency, and at the same time, the purification of water quality cannot be completely realized only through phenolic spherical resin groups, which makes this technical solution limited.
