Description
Technical field
The present invention relates to a sewage water treatment method, in particular to a kind of industrial sewage treatment technology.
Background technique
With China's industrial development, a large amount of trade effluents and sanitary sewage are produced, pollution on the environment influence is got over
Come more next obvious.The highly difficult sewage wherein discharged, such as chemical engineering sewage, petrifaction sewage, coked waste water, landfill leachate, pharmacy
Sewage, plating cyanogens-containing sewage water, grinding sewage etc., contain many refractory organics and bio-toxicity object in these sewage
Matter, organic components are complicated, and COD COD concentration is high, and such sewage is very difficult.In recent years, China is highly difficult
Field of sewage treatment has many researchs and technological development, but corresponding environmentally friendly task is still very arduous.At present for highly difficult
Sewage water treatment method have Fenton process, O3 catalytic oxidation method, microwave method, electrolytic catalysis method, incineration method, activated sludge process, at film
Logos, other biological method etc..It studies and what experiment use was more is Fenton process, be in acid condition, with ferrous ion Fe2+
The sewage water treatment method of chemical oxidation is carried out with hydrogen peroxide H2O2 for catalyst.The body being made of ferrous ion and hydrogen peroxide
System, also referred to as Fenton reagent, it can generate the hydroxyl radical free radical of strong oxidizing property, generate in aqueous solution with hardly degraded organic substance organic
Free radical is allowed to structure and destroys, final oxygenolysis, meanwhile, 3 colloid of Fe (OH) for reacting generation has flocculation, adsorption function,
Adsorption water part organic matter.But Fenton process installation area is big, and dosing adapter tube is complicated, and amount of consumption of drugs is big, reagent cost
Height needs readjustment pH and precipitating after reaction, be also easy to produce more sludge dangerous waste, and operation Chinese medicine launches proportion requirement height, reaction condition
It is required that more, treatment effect is unstable, limits industrially scalableization development.
Summary of the invention
It is an object of the present invention to provide a kind of processing method is simple, at high treating effect and low-cost trade effluent
Reason method.
In order to achieve the above objectives, the method that the present invention uses is: a kind of industrial sewage treatment technology, including following step
It is rapid:
(1) using sewage pump by sewage through the coarse solid sundries in grid decontamination water, then by sewage be sent into setting pot in into
Row precipitation process；
(3) sewage will be settled in setting pot drain into anaerobic fixed film reactor and carry out Anaerobic Treatment in anaerobic zone add carbon containing battalion
Nitrate nitrogen is reduced into nitrogen discharge by nutrient solution, the denitrifying bacterium in sewage；
(4) sewage crossed through Anaerobic Treatment is sent into anoxic zone and carries out anoxic treatment；
(5) it will be sent into catalyst reaction pond through the processed sewage in anoxic zone, will further be reacted by adding catalyst；
(6) ozone reaction tower will be sent by the sewage of step (5) processing to react；
(7), it will be sent into secondary settling tank by the sewage of ozone reaction, and flocculant be added and carries out flocculation treatment, isolated
Sediment；
(8), it will be discharged after the sewage that step (7) is handled is filtered by packing layer.
As an improvement of the present invention, the ingredient of the flocculant are as follows: the ferric sulfate of 5-12 parts by weight, 10-15 weight
Measure the ferric trichloride of part, the ferrate of 5-10 parts by weight；Polyacrylamide, gelatin, the soluble cellulose of 8-15 parts by weight
Mixture.
The utility model has the advantages that
The present invention passes through precipitating pretreatment, hydrolysis acidification, low-level oxidation, aerobic-anaerobic coupling technique and flocculation treatment
Combine, simple process, effect is good, percent of decolourization, COD, BOD removal rate, and tp removal rate is high, and solid residues amount is small, and at
This is cheap, is suitble to promote.
