Description
Technical field
The present invention relates to a kind of chemical industry reagent, specifically a kind of wastewater from chemical industry flocculant.
Background technology
Wastewater from chemical industry is varied, and majority has severe toxicity, is difficult to purify, has certain summation in vivo, in water
There is in body obvious oxygen consumption property, easily make water quality deterioration.Have the following characteristics that water-quality constituents is complicated, by-product is many, reaction is former
Material is often the compound of solvent material or circulus, increased the intractability of waste water；Pollutants in Wastewater content is high, this
It is that not exclusively and used in raw material or production, solvent mediums enter caused by waste water system in a large number due to raw material reaction；
Poisonous and harmful substance is many, has many organic pollutions to be poisonous and hazardous to microorganism in Fine Chemistry Wastewater.As halogen chemical combination
Thing, nitro compound, the dispersant with bactericidal action or surfactant etc.；Bio-refractory material is many, and b/c ratio is low, can
Biochemical is poor；Chroma in waste water is high.The feature of wastewater from chemical industry has following several respects: 1. toxic and zest.Contain in wastewater from chemical industry
There are many pollutant, some are materials that is poisonous or having severe toxicity, such as cyanogen, phenol, arsenic, hydrargyrum, cadmium and lead etc., some materials are difficult point
Solve, long term accumulation can cause to be poisoned in vivo, such as organochlorine compound；Some are purportedly carcinogen, such as polycyclic aromatic hydrocarbon
Compound etc.；Additionally, also having some irritant, corrosive materials, such as mineral acid, bases etc.；2. Biochemical oxygen demand and change
Learn oxygen demand all higher.Wastewater from chemical industry contains various organic acid, alcohol, aldehyde, ketone, ether and epoxide etc., and being characterized in biochemical needs
Oxygen amount and COD are all higher.This waste water once entering water body, will in water further oxidation Decomposition, thus consuming
Substantial amounts of dissolved oxygen in water, directly threatens hydrobiological existence；3. ph is unstable.The waste water of Chemical Manufacture discharge, Shi Ercheng
Highly acid, when and be in strong basicity, ph is unstable, has high risks to aquatile, structures and crops；4. nutrition compound
Matter is more.The phosphorous, nitrogen quantity having in chemical production wastewater is too high, causes waters eutrophication, makes algae and microorganism in water big
Amount breeding, also can form " red tide " when serious, cause the large quantities of death of Fish；5. wastewater temperature is higher.Because chemical reaction often exists
Carry out under high temperature, the waste water water temperature of discharge is higher.The thermal pollution of water body after this hot waste water enters waters, can be caused, make water
Middle dissolved oxygen reduces, thus destroying hydrobiological conditions of existence.6. oily pollution is more universal.General in petrochemical wastewater
All contain oils, not only endanger hydrobiological existence, and increased the complexity of wastewater treatment；7. recover relatively difficult.
The waters polluted by chemical industry harmful substance, though reduce or stop pollutant discharge, waters original state will be returned to it is still necessary to
For a long time, especially for the heavy metal contaminants being enriched with by biology, remain difficult to after stopping discharge eliminating pollution shape
State.
Wastewater from chemical industry is directed to the feature of different polluters, has developed various different chemical wastewater treatment methods, these
Processing method is divided into four big class: physical treatment process, method of chemical treatment, physical-chemical process and biological treatment by its action principle
Method.Wastewater from chemical industry physical treatment process pass through physical action, with separate, reclaim waste water in undissolved in suspended state polluter
Waste water treatment process, according to the difference of physical action, gravitational separation process, centrifugal separation and sieving retention method etc. can be divided into again.
Physical has the advantages that equipment is simple, low cost, convenient management, effect stability, be mainly used in removing floating thing in waste water,
The materials such as suspended solid, sand and oils, including filtration, Gravity Separation, centrifugation etc..Wastewater from chemical industry method of chemical treatment passes through to change
Learn reaction and effect of mass transmitting to separate, to remove in waste water in dissolving, the polluter of colloidal state or be translated into harmless object
The waste water treatment process of matter.Can be used to remove the metal ion in waste water, tiny colloidal organic matter, inorganic matters, nutrient for plants
(nitrogen, phosphorus), oil emulsion, colourity, stink, acid, alkali etc., including methods such as neutralisation, Coagulation Method, oxidoreduction, electrochemistry.Change
Work waste water physical-chemical process utilizes physics chemical action to remove the polluter in waste water.After waste water is processed through physical method, still
The Organic substance of some tiny float and dissolving can be contained, in order to remove the pollutant remaining in water further, can enter
One step is processed using physico-chemical process, mainly have absorption method, ion exchange, membrane separation process, extraction, vaporizing extract process and
Blow-off method etc..The metabolism by microorganism for the wastewater from chemical industry biochemical treatment method, makes to be in solution, colloid and micro- in waste water
The Organic polluter of thin suspended state is converted into stable, harmless method of wastewater treatment.The essence of biological treatment process is
A kind of Organic substance catabolic process being participated in by microorganism carrying out, the microorganism of decomposing organic matter is mainly antibacterial, other microorganisms
As algae and protozoacide also assist in this process, but effect is less.
Wastewater from chemical industry environmental pollution is very big, carries out processing very necessary, existing production is relatively costly, is unfavorable for
Popularize in an all-round way and apply.Chemical wastewater treatment industry now, water quality is increasingly sophisticated, and the requirement to Water Treatment Chemicals also carries increasingly
High.The polymer flocculants polyacrylamide commonly used in the market, the monomer structure of employing is more single, and product uses face narrow
Narrow it is impossible to meet the requirement of different industries different quality.
