Abstract
The invention discloses a method for treating heavy metal wastewater during a machining process. The treating method is implemented by the following steps of: wastewater reclamation, putting of chemical agents, degradation, ion exchange, regeneration, washing, drying and discharging. Compared with the prior art, according to different water quality requirements, the method achieves comprehensive balance, series flow usage, high efficiency, quick reaction, universality and thoroughness, and meanwhile can improve the water quality stabilizing measure and continuously improving the circulation utilization rate of the water.
Description
technical field:
The present invention relates to process for treating heavy-metal waste water in a kind of course of processing.
background technology:
Along with the development of science and technology and the continuous progress of society, industrial technology and technique are ripe gradually, for industrial production enterprise brings larger interests.But in the industrial production due to a lot of complicated production technique and production technology can be related to, add the severe of industrial process conditions, cause giving off a lot of with serious pollution water in process of production.Water is mankind's resource of depending on for existence and basic guarantee, so improve the quality of water, water conservation is an important topic of society.Therefore need to process these trade effluents, reach the requirement of purification.
In recent years, along with industrial development and progress, the quantity discharged of waste water is increased year by year, not only destroy ecological resources balance, also have impact on the living environment of people, hinder the development of society.So need to strengthen the research and exploitation to process for treating industrial waste water, formulate effective strategy to improve the depuration quality of sewage.In Industrial Wastewater Treatment, the main mode adopted has physical treatment process, chemical treatment method, biological treatment and electrochemical treatment etc. at present, to some extent solves the process problem of waste water, but there is a little deficiency in the application.Existing treatment process cannot realize cleaner production, and resource is taken as waste and slatterns.In addition, exist waste water be difficult to stably reaching standard discharge, process water can not reuse, mud thing dispose and reclaim difficulty etc. problem.
summary of the invention:
The object of the invention is to: overcome the deficiencies in the prior art, process for treating heavy-metal waste water in a kind of course of processing is provided, be used for realizing the recycling of heavy metal in waste water and the zero release of waste water.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
Process for treating heavy-metal waste water in a kind of course of processing, comprises the following steps:
(1) waste water reclamation: the waste water reclamation that the course of processing is produced;
(2) chemical agent is thrown in: injected volume is the activated carbon fiber of H2O2 and 50-100mg/l of 15-25mg/l simultaneously in the photochemical reaction pond filling polluted source water;
(3) degrade: pass into the O3 of 5-10mg/l and carry out ultraviolet degradation while passing into O3, degradation time is 30min-50min.
(4) ion-exchange: regulate PH value to be 8 ~ 11 waste water of weakly acidic cation-exchange resin process, then carry out ion-exchange with strongly basic anion exchange resin
(5) regenerate: storng-acid cation exchange resin sulphuric acid soln zeolite regeneration, the water after gained regenerated liquid neutralizing treatment is with zero release of pollutant
(6) wash: invade bubble 15-20 minute clean dirt stain with the heavy metal of the clear water of 40 DEG C to absorption;
(7) dry: seasoning of being exposed to the sun under the heavy metal after cleaning is placed on sufficient sunlight;
(8) discharge: the trade effluent of the standard that reaches after process is discharged.
In the course of processing of the present invention, process for treating heavy-metal waste water advantage is:
1. process for treating heavy-metal waste water in the course of processing of the present invention, compared with prior art, the present invention is according to different quality requirement, overall equilbrium, crossfire uses, and high efficiency, reaction are fast, universality and thoroughness, water conditioning measure can be improved simultaneously, improve constantly the cyclic utilization rate of water.
embodiment:
Below in conjunction with embodiment, the invention will be further described.
Process for treating heavy-metal waste water in a kind of course of processing, comprises the following steps:
(1) waste water reclamation: the waste water reclamation that the course of processing is produced;
(2) chemical agent is thrown in: injected volume is the activated carbon fiber of H2O2 and 80-100mg/l of 20-25mg/l simultaneously in the photochemical reaction pond filling polluted source water;
(3) degrade: pass into the O3 of 8-10mg/l and carry out ultraviolet degradation while passing into O3, degradation time is 40min-50min.
(4) ion-exchange: regulate PH value to be 10 ~ 11 waste water of weakly acidic cation-exchange resin process, then carry out ion-exchange with strongly basic anion exchange resin
(5) regenerate: storng-acid cation exchange resin sulphuric acid soln zeolite regeneration, the water after gained regenerated liquid neutralizing treatment is with zero release of pollutant
(6) wash: invade bubble 18-20 minute clean dirt stain with the heavy metal of the clear water of 40 DEG C to absorption;
(7) dry: seasoning of being exposed to the sun under the heavy metal after cleaning is placed on sufficient sunlight;
(8) discharge: the trade effluent of the standard that reaches after process is discharged.
Certainly, above-mentioned explanation is not limitation of the present invention, and the present invention is also not limited to above-mentioned citing; those skilled in the art; in essential scope of the present invention, the change made, change, interpolation or replacement, all should belong to protection scope of the present invention.
