Embodiment Construction

[0028] Such as figure 1 and figure 2 Shown, a kind of waste emulsion of the present invention, electroplating waste water, landfill leachate comprehensive treatment technology, comprises the following several steps:

[0029] 1) Lift the waste water to be treated into the demulsification reaction kettle through the water pump, add sulfuric acid through the dosing device for acidification treatment, the waste water appears milky yellow and turbid, after acidification, steam the waste water in the kettle to heat up, and add a certain amount of sulfurous acid iron;

[0030] 2) When the temperature of the wastewater rises to about 80°C, the emulsified state of the wastewater appears to be cracked, and the pH of the wastewater is adjusted to about 9-10 by adding lime milk solution to maintain the temperature. Ferrous hydroxide floc precipitates appear in the water body, and further PAM is added. The coagulant can completely flocculate the water body, so that the wastewater can be...

Abstract

The invention discloses an integrated disposal technology for waste emulsion liquid, electroplating wastewater and landfill leachate. The integrated disposal of the waste emulsion liquid, electroplating wastewater and landfill leachate can be implemented by utilizing demulsification, oxidation pre-treatment and biological treatment. According to the integrated disposal technology for waste emulsion liquid, electroplating wastewater and landfill leachate, provided by the invention, the demulsification of various waste emulsion liquid with high COD can be implemented, the waste emulsion liquid, the electroplating wastewater and the landfill leachate can be disposed in the same disposal facility to reach the emission standard, the equipment is compact, and the investment is low.

Description

technical field [0001] The invention relates to a comprehensive treatment technology for waste emulsion, electroplating wastewater and landfill leachate, belonging to the technical field of hazardous waste treatment. Background technique [0002] Emulsion wastewater is a common wastewater produced in factory production, which is characterized by a wide variety, COD cr The concentration of oil content is high, and the treatment is difficult; the concentration of metal ions in electroplating wastewater is high; the leachate of landfill site is difficult to degrade COD, and the content of ammonia nitrogen is high; the existing disposal technology is mostly used for waste emulsion, electroplating wastewater, and landfill leachate Separate disposal, the investment is relatively high. [0003] In the prior art, general demulsification treatments include salting-out method, coagulation method, acidification method, mixing method and the like. [0004] The salting-out method is to...
