Seriously, the health and safety of the mankind is threatened.For protection environment, the processing of industrial wastewater than municipal sewage processing more
It is important.In industrial wastewater, high concentration organic acid and aldehydes contaminated wastewater are particularly pertinent.The main feature COD of aldehydes waste water is dense
Degree is high, and bio-toxicity is big, belongs to high-concentration hardly-degradable waste water.Aldehyde-containing type wastewater biodegradability is generally preferable, but it has a bit
Bio-toxicity can have inhibiting effect to microorganism when aldehyde content is higher in waste water to influence biological treatment effect.Aldehydes
Especially formaldehyde waste water bio-toxicity, pollution toxic are especially prominent in waste water.Formaldehyde to the toxicity of people and warm-blooded animal very
By force, it can stimulate skin, and Yi Yinqi dermatitis is also easy to produce respiratory tract, allergy, abnormal pulmonary function, dysfunction of liver, immune function
It can wait extremely.If mankind's long-term drinking can cause dizzy, anaemia and various nervous system diseases by the water source of formaldehyde pollution
Disease.The COD concentration of high concentration organic acid and aldehydes waste water is larger, and stronger acidity is presented in this kind of waste water more, and wastewater pH is mostly 1
~2 or so.Organic acid has stronger toxicity and carcinogenicity, such waste water can not only cause the loss of agricultural and fishery, and
It is detrimental to health.Simultaneously as such waste water has stronger acidity, cause its biodegradability very poor, it is difficult to straight
Tap into row biochemical treatment.Domestic at present more to the research of high concentration organic acid and aldehydes wastewater treatment, processing method is respectively not
It is identical, and it is crucial for selecting a low cost, the technique of high removal rate.
Summary of the invention
Place in view of the shortcomings of the prior art, the object of the present invention is to provide a kind of organic acid containing high concentration and aldehyde
The processing method of class waste water reduces by the way that acid proof and oxygen bacterium is added in reaction tank and adjusts wastewater pH step, thus simple
Chemical industry skill reduces cost.
For the attainment of one's purpose, technical solution provided by the invention are as follows:
A kind of processing method of organic acid containing high concentration and aldehydes waste water, which is characterized in that itself the following steps are included:
(1) waste water is entered into conditioning tank, goes impurity removing, uniform water quality, stationary flow amount；
(2) step (1) treated waste water is entered in HBR reaction tank by elevator pump, is placed in advance in HBR reaction tank
Nitrogenous compound is added in HBR reaction tank in acid proof and oxygen bacterium, phosphorus-containing compound is reacted；
(3) waste water outflow after step (2) reaction enters UASB anaerobic reactor, under anaerobic, it is anti-to carry out anaerobism
It answers
(4) waste water outflow after step (3) reaction enters level-one aerobic tank, carries out Aerobic Process for Treatment；
(5) waste water outflow after step (4) reaction enters anaerobic pond, carries out depth hydrolysis' acidification；
(6) waste water outflow after step (5) reaction enters the reaction of the pond BAF；
(7) waste water after step (6) reaction is detected, qualified discharge, then return of waste water not up to standard to step (2).
Preferably, in step (1), residence time of the waste water A in conditioning tank is 1~5 day.
Preferably, acid proof simultaneous oxygen bacterium can be by persistently feeding formic acid solution, formic acid solution to simultaneous oxygen bacterium
Concentration is gradually deepened, and by cultivating, taming and screening for a long time, finally obtains a kind of extremely strong simultaneous oxygen bacterium of acid resistance.
Preferably, in step (2), the range of reaction temperature in HBR reaction tank is at 10~55 DEG C, and pH value range is 5~10
Between, sludge concentration range exists in 1000~6000mg/L, oxyty range in 0.2~0.8mg/L, volumetric loading range
0.3~5kgCOD/ (m3*d)。
Preferably, in step (2), the nitrogenous compound is one of urea, ammonium salt, nitrate, nitrite or appoints
The mixture aqueous solution of meaning ratio, nitrogenous compound solution concentration range is 0.1~10%.
Preferably, in step (2), the phosphorus-containing compound is the mixed of one of phosphoric acid, potassium dihydrogen phosphate or arbitrary proportion
Object aqueous solution is closed, phosphorus-containing compound solution concentration range is 0.1~10%.
Preferably, in step (3), the range of reaction temperature in UASB anaerobic reactor is at 15~55 DEG C, and pH value range is 5
Between~10, volumetric loading range is in 0.01~10kgCOD/ (m3*d)。
Preferably, in step (4), the range of reaction temperature in level-one aerobic tank is at 10~55 DEG C, and pH value range is 6~9
Between, sludge concentration range in 10~50000mg/L, oxyty range in 0.5~9mg/L, volumetric loading range 0.1~
2.8kgCOD/(m3*d)。
Preferably, in step (5), range of reaction temperature in anaerobic pond at 15~55 DEG C, pH value range between 6~9,
Volumetric loading range is in 0.1~3.0kgCOD/ (m3*d)。
Preferably, for the range of reaction temperature in step (6) in the pond BAF at 15~55 DEG C, pH value range is molten between 6~9
Oxygen ranges are in 0.5~8mg/L, and volumetric loading range is in 0.1~2.3kgCOD/ (m3*d)。
Using technical solution provided by the invention, compared with prior art, have the following beneficial effects:
