Description
Technical field
The present invention relates to trade effluent innoxious process for treating field, be related specifically to be applicable to high-concentration chemical industry sewage
Processing method.
Background technology
Chemical engineering sewage refers to that chemical plant produces the sewage produced in product process, as produce ethylene, polyethylene, rubber,
The oil-polluted water of the devices such as polyester, methanol, ethylene glycol, Oil Tank, space division air compression station.The water-quality constituents of chemical engineering sewage is complicated,
Water-quality constituents is complicated, and by-product is many, and reaction raw materials is often the compound of solvent material or circulus, adds the place of sewage
Reason difficulty.
Chemical engineering sewage pollutes generally following characteristics: 1, toxic and zest.In chemical engineering sewage some contain as cyanogen,
Poisonous or the hypertoxic materials such as phenol, arsenic, hydrargyrum, cadmium or lead, under certain concentration, produce toxic effect to biological and microorganism.
Additionally it is likely to containing the zest such as mineral acid, bases, corrosive material.2, organic concentration is high.Particularly petrochemical industry
In sewage, the organic concentration such as various organic acid, alcohol, aldehyde, ketone, ether and epoxide is higher, can oxidation point further in water
Solve, consume substantial amounts of dissolved oxygen in water, directly affect hydrobiological existence.3, pH is unstable.During the sewage of chemical industry emission and
Highly acid, time and alkaline phenomenon often has, biological, building and crops are had harm greatly.4, nutrient laden
Material is more.The sewage that phosphorous, nitrogen quantity is higher can cause body eutrophication, makes algae and microorganism amount reproduction in water, sternly
" red tide " can be caused during weight, affect fish growth.5, recover relatively difficult.The waters water to be returned to polluted by harmful substance
The initial condition in territory is extremely difficult.Especially by the heavy metal substance of Institute of Micro-biology's concentration, stop discharge and be still difficult to eliminate.
The processing method of the chemical engineering sewage that application is wider is broadly divided into Physical and chemical method at present.Physical includes filtering
Method, the gravitational settling gentle float glass process of method etc..Filtration is to have hole granular pellet layer to retain impurities in water, mainly reduces in water
Float, in the filtration treatment of chemical engineering sewage, conventional pull frame filter and microporous filter, microporous pipe is by polyethylene system
Becoming, pore size can be adjusted, and exchanges more convenient；Gravitational settling method is to utilize the precipitable performance of particle in water,
Natural subsidence effect under the effect of gravitational field, to reach a kind of process of solid-liquid separation；Air supporting method is micro-by generating absorption
Minute bubbles are attached wraps up in the method carrying particle and take the water surface out of.These three physical method technique is simple, convenient management, but can not
It is applicable to the removal of solubility sewage composition, there is significant limitation.Chemical method is that the effect utilizing chemical reaction is to go
Except the Organic substance in water, inorganic contaminants.Mainly there are chemical coagulation process, chemical oxidization method, electrochemical oxidation process etc..Chemical coagulation
Method effective object is mainly small float and colloidal substance in water, by adding cohesion and the flocculation work that chemical agent produces
With, make elimination of colloid stability form precipitation and remove.Coagulation Method not only can remove the tiny suspension that the particle diameter in sewage is 1～10mm
Granule, and colourity, microorganism and Organic substance etc. can also be removed.The method is by change shadows such as pH value, water temperature, water quality, the water yields
Ringing big, the organic and inorganic material clearance good to some solubility is low；Chemical oxidization method is typically with oxidant chemical engineering sewage
In the organic pollution method that carries out oxidation removal.Sewage through chemistry redox, can make contained organic in sewage and
Inorganic noxious substance is transformed into nontoxic or that toxicity is less material, thus reaches the purpose of sewage purification.Conventional has air
Oxidation, oxychloride and ozonization method.Air oxidation is weak because of its oxidability, is mainly used at the sewage containing the stronger material of reproducibility
Reason, Cl is commonly used oxidant, is used primarily in containing in phenol, process containing organic sewages such as cyanogen, processes sewage, oxygen with ozone
Change ability is strong, non-secondary pollution.Ozonation, oxychloride method, its water treatment efficiency is good, but energy consumption is big, and cost is high, uncomfortable
Conjunction processes the chemical engineering sewage that the water yield is big and concentration is relatively low；Electrochemical oxidation process is in a cell, the organic contamination in sewage
Thing is owing to occurring redox reaction to remove on electrode, and it is oxidized that dirty water pollutant loses electronics at the anode of electrolysis bath
Outward, the Cl-in water, OH-etc. also can generate Cl2 and oxygen and Oxidative demage pollutant indirectly at anode discharge.It practice, be
The Oxidation of strengthening anode, reduces the internal resistance of electrolysis bath, often adds some sodium chloride in electrolytic sewage groove, carry out what is called
Electric chlorination, NaCl can generate chlorine and hypochlorite at anode after adding, and also has stronger to the inorganic matter in water and Organic substance
Oxidation.In terms of electroxidation and electroreduction, it is found that some new electrode materials in recent years, achieves certain effect, but still
Have that energy consumption is big, cost is high, and there is the problems such as side reaction.
Therefore, a kind of processing method being applicable to high-concentration chemical industry sewage is developed, enabling effectively remove in sewage
Organic substance, nitrogen, phosphorus, and reduce acidity, just it is particularly important.
