Abstract
The invention relates to an environment-friendly electroplating wastewater treatment device, which performs a treating process to treat acidulous wastewater containing silver ions into clear alkalescent water which does not contain the silver ions and accords with the industrial discharge requirement. The treating process comprises the following implementation steps: 1) designing and manufacturing a wastewater treatment device which is arranged below an environment-friendly electroplating production line and comprises a waste liquid treatment tank, a salt water tank, a lime water tank, an active carbon filter tank and a water pump; 2) introducing salt water containing 20 percent of NaCl and lime water into the waste liquid which is generated in the environment-friendly electroplating process and flows to a waste material liquid treatment tank so that the salt water neutralizes the silver ions in the waste liquid and the lime water neutralizes the alkalescence of the waste liquid; and 3) pumping the neutralized water to a device provided with an active carbon filter by the water pump so as to filter and remove suspended substances.
Description
Technical field
The environment-protection electroplating liquid waste treating apparatus utilizes chlorion and silver ions to generate the silver nitride precipitation thing and removes silver ions in the waste liquid, utilize in the caustic lime water and waste liquid in acid ion, again with gac device filter and remove suspended substances.
Background technology
The present invention is directed to me and take charge of the waste water that environment-protection electroplating technology newly developed produces.The environment-protection electroplating technology is a kind of novel surface treatment technology newly developed; be on product, to handle one deck silver and protective layer; its process is different from traditional plating fully; can produce waste liquid in the treating processes; contain the silver ions that concentration is about 0.1-0.3% in the waste liquid; and being slightly acidic, its pH value is about 3-4.
Summary of the invention
The present invention becomes the limpid treating processes that meets the alkalescent water that industrial discharge requires of argentiferous ionic not to the slightly acidic wastewater treatment that contains silver ions.
Implementation step is as follows:
1) design and produce a wastewater treatment equipment, this device be installed in the environment-protection electroplating production line below.Wastewater treatment equipment contains liquid waste disposal groove, saline slot, lime tank, activated carbon filtration groove and a lift pump.
2) waste liquid that produces of environment-protection electroplating flows in the waste and old material liquid treatment trough, feeds the salt solution and the liming that contain 20%NaCl, in the salt solution and the silver ions in the waste liquid, in the liming and the weakly alkaline in the waste liquid.
3) be extracted in the device that has activated carbon filtration filter and remove suspended substances by water pump through neutral water.
Embodiment
Example 1: the preparation of the making of equipment and processing liquid medicine
1) equipment making: the PVC plate that equipment is used is welded, and last the filtration together put gac in device bottom, adopts the chemical pump of low noise.The thickness 10mm of PVC plate.Gac need regularly replace.
2) liquid medicine proportioning: salt solution is equipped with according to 20% NaCl, and liming uses unslaked lime to add bubble system, gets the clarification part.
3) operation steps:
A, waste water flow in the reactive tank, and salt solution and liming are in two other tanks, and salt solution and liming flow in the wastewater trough simultaneously, make the silver ions precipitation in the waste liquid, in and the acidity of waste water.
Waste water in the waste liquid tank after B, the neutralization is extracted into by water pump and filters and remove suspended substance in the appliance arrangement that has gac.Behind activated carbon filtration equipment, outfall sewer is effusive to be exactly limpid alkalescent water, and pH value can be controlled in about 8.
Description of drawings:
Fig. 1 is an environment friendly electroplating waste processing equipment.
Claims (1)
- Environment friendly electroplating waste processing equipment technical matters key point is to use sodium chloride solution precipitated silver ion, in the liming and the acidity in the waste liquid, makes it become weakly alkaline water, then with gac device filter and remove suspended substances.Last outfall sewer flows out limpid alkalescent water.Claimed following project:1) by the chlorion precipitated silver ion in the sodium chloride solution;2) pass through in the liming and the acidity in the waste liquid;3) filter the removal floating matter by the gac device.
