Description

A kind of mercurous sewage water treatment method
Technical field
The present invention relates to heavy metal-polluted water-treatment technology field, and in particular to a kind of mercurous sewage water treatment method.
Background technology
Heavy metal original meaning refers to metal of the proportion more than 5（Density is more than 4.5 grams of metals per cubic centimeter）, including gold, Silver, copper, iron, lead etc..Heavy metal pollution is different from the pollution of other organic compounds.Many organic compounds can be by nature Boundary's physics, chemical or biology purification in itself, makes harmfulness reduction or releases.And heavy metal has enriching, it is difficult to Degraded in environment.At present China due in the exploitation of heavy metal, smelting, process, cause many heavy metals for example lead, mercury, Cadmium, cobalt etc. cause serious environmental pollution into big gas and water, soil.The heavy metal such as discharged with waste water, even if concentration is small, Can be accumulated in algae and bed mud, be adsorbed by fish and shellfish body surface, food chain concentration be produced, so as to cause public hazards.
Mercury (Hg) is one of most strong heavy metal element of environment Poisoning.The minamata disease thing of the 1950's Japan's generation Part, makes people be fully recognized that mercury, especially murder by poisoning of the methyl mercury (MeHg) to human body and animal.60-eighties of 20th century, Scholars have made intensive studies to the circulation Evolution of artificially-contaminated aquatic ecosystem mercury, and to MeHg to human body The mechanism of murder by poisoning has carried out further investigated, obtains MeHg and can be enriched with by aquatic food web and amplifies, biological in high nutrition level In highly enriched and MeHg can be hindered by human body blood and brain hinders the understanding that harm is produced to the central nervous system of people.
Traditional mercury-containing waste water treatment method mainly has chemical precipitation method, metal deoxidization, active carbon adsorption, ion to hand over Change method, electrolysis and microbial method.Chemical precipitation method advantage：It is the prioritizing selection of high concentration mercury ion wastewater treatment, technology is held Easily realize.Shortcoming：It is not thorough to Low Concentration Mercury wastewater treatment.Metal deoxidization can the single mercury-containing waste water of processes composition, reaction Speed is high, but demercuration is incomplete.Active carbon adsorption in demercuration efficiency mercury content Gao Shiyou very high, when mercury content is low under efficiency Drop,；Shortcoming：Complex operation, high cost, variation water quality are easily caused exceeded.Ion-exchange is influenceed greatly by impurities in water, cost It is high.Electrolysis can process up to standard, but cost of investment is high, power consumption is big, easily generation mercuryvapour causes secondary pollution.Microbial method is in examination Test in research and present vast potential for future development, but still there are many problems to constrain its industrial applications.
The content of the invention
A kind of advantage and disadvantage the invention aims to be directed to above-mentioned each processing method, there is provided mercurous sewage disposal side Method.This is a kind of preferably mercurous sewage water treatment method for the treatment of effect, and specially applicable concentration is relatively low, demercuration efficiency is higher, Mercurous concentration is relatively low after final process, the relatively low mercurous sewage water treatment method of cost.
In order to reach foregoing invention purpose, the present invention uses following technical scheme：
A kind of mercurous sewage water treatment method, specifically includes following steps：

（2）Then the pH containing Mercury sewage is adjusted to 8.3-8.5, composite flocculation agent is then added wherein, protected after stirring 1-2h is held, the addition of composite flocculation agent is every cubic metre and adds 10-100g, composite flocculation agent to count by weight containing Mercury sewage Including：Potassium pyrophosphate 1-3 parts, sodium carboxymethylcellulose 10-12 parts, water soluble chitosan 5-8 parts, polyacrylamide 15-18 parts With sodium diethyldithiocarbamate 3-5 parts；
（3）Being precipitated containing Mercury sewage and being filtered after by treatment, the sedimentation time is 2-10h；
（4）PH is adjusted for 6.5-7 containing Mercury sewage after to filtering, then every cubic metre containing Mercury sewage addition 5-20g two Level inorganic agent, keeps 2-5h after stirring, two stage treatment agent count by weight including：Sodium hypochlorite 1-4 parts, ethylenediamine tetraacetic Acetic acid 3-5 parts, citric acid 8-10 parts and AEO 4-6 parts；
（5）The 0.3-1 containing addition bodied ferric sulfate and polyaluminium sulfate in Mercury sewage after treatment:10 mixture, mixing The addition of thing is every cubic metre and adds 5-100g containing Mercury sewage；
（6）Water up to standard is obtained after finally filtering.
For the addition of composite flocculation agent, the content with specific reference to mercury is suitably adjusted, when by step（1）Treatment In sewage afterwards, when the content of mercury is more than 0.8mg/L, the addition of composite flocculation agent is more than 70g；
Used as preferred scheme, the composite flocculation agent also includes sodium 3-5 parts of iminodisuccinic acid four.
Being capable of faster processing time.
As preferred scheme, the step（2）Composite flocculation agent count by weight including：3 parts of potassium pyrophosphate, carboxylic 3 parts of 10 parts of sodium carboxymethylcellulose pyce, 5 parts of water soluble chitosan, 15 parts of polyacrylamide and sodium diethyldithiocarbamate.
As preferred scheme, the step（3）Two stage treatment agent count by weight including：3 parts of sodium hypochlorite, second 4 parts of 3 parts of ethylenediamine tetraacetic acid (EDTA), 10 parts of citric acid and AEO.
As preferred scheme, the step（2）Treatment temperature be 26-30 DEG C.
As preferred scheme, the step（5）Middle elder generation processed at every cubic metre in containing Mercury sewage in add sulfuric acid sub- Iron, after stirring 1h, then filtering obtains water up to standard with charcoal absorption.The addition of ferrous sulfate is 10-50g/L.
Compared with prior art, beneficial effect is the present invention：
1st, this method is combined to being processed containing Mercury sewage using multistep, wherein, in step（3）Sewage after treatment, total mercury Content can just reach the standard of national composite wastewater discharge standard GB8978-1996, i.e.,<50ppb；In step（5）And it is last The sewage total mercury content that treatment is obtained can reach<The chlor-alkali industry standard of 5ppb；
2nd, the processing procedure process is simple of this method, equipment investment is relatively low；
3rd, the treatment effeciency of this method is of a relatively high, it is not necessary to the precipitation of many days and other treatment, greatlys save disposal ability；
4th, the sewage for finally obtaining reduces the content of mercury, and main composition is the salt and organic being easily processed, after being easy to Continuous treatment again.
5th, this method carries out disposed of in its entirety for the comprehensive wastewater of organic mercury and inorganic mercury, with adaptability.
