Abstract
The invention discloses the processing method of a kind of chlopyrifos waste water, comprise the following steps: the degradation efficiency of organophosphor of the present invention is high, the general electrolysis of ratio, the biodegrading process such as Fenton process is easier to up to standard；Phos after degraded is prepared as guanite, and indices therein has all reached country and utilized standard, produces a large amount of abraum salt waste organic matters than evaporation and decreases secondary pollution；After organophosphor is degraded, the biodegradability of waste water is greatly improved, the indices of bio-chemical effluent all can meet discharging standards, simultaneously, trichloro pyridyl sodium alcoholate in the basic degrading waste water of microorganism energy of specific culture, water outlet trichloro pyridyl sodium alcoholate concentration is less than 1ppm, and after solar irradiation, waste water no longer reddens.
Description
Technical field
The invention mainly relates to a kind of method, particularly relate to the processing method of a kind of chlopyrifos waste water.
Background technology
Chlopyrifos is a kind of broad spectrum activity organophosphorus compounds that first Dow Chemical company developed in nineteen sixty-five
Insecticide, has efficiently, wide spectrum, low-residual and low drug-fast feature, have tag, stomach toxicity and steaming three
Recast use, to chewing type multiple on paddy rice, wheat, cotton, fruit tree, vegetables, tea tree and sucking mouth parts evil
Worm is respectively provided with favorable effect.Toxicity is low compared with conventional pesticide, to natural enemies security, is to substitute high-toxic organic phosphorus agriculture
The first-selected medicament of medicine (such as 1605, acephatemet, omethoate etc.).Chlopyrifos to preventing and treating diseases and pests of agronomic crop and
Ectozoa of domestic animals is the most significant.
Chlopyrifos pesticides produces in waste water containing the hardly degraded organic substance such as substantial amounts of organophosphor, trichloropyridine alcohol, has
Machine phosphorus can cause the serious ecological environment problems such as body eutrophication after entering water body.Additionally waste water contains
Trichloro pyridyl sodium alcoholate enables to water body and becomes red under the irradiation of sunshine, extremely affects visual perception.One
As organism P wastewater processing method include evaporative crystallization method, electrolysis, Fenton oxidation method etc., but these sides
Method treatment effeciency is low, and organic phosphorus degrading is thorough, often easily forms the water after secondary pollution, and process
Can not qualified discharge.Catalyzing hydrolysis oxidizing process is to utilize hydrogen peroxide and catalyst under the acid condition of HTHP
Be hydrolyzed reaction to the organic matter in chlopyrifos waste water so that the organophosphor in water body becomes phosphoric acid salt, then
The method removed by the precipitation method.It is high that the method has treatment effeciency, and the features such as cost is relatively low successfully solve
Chlopyrifos waste water difficult degradation, high saliferous, easy to change wait challenge.
Summary of the invention
The object of the invention is just to provide the processing method of a kind of chlopyrifos waste water.
The present invention is achieved by the following technical solutions:
The processing method of a kind of chlopyrifos waste water, comprises the following steps:
(1) waste water per ton adds hydrochloric acid 18-22 kilogram that mass fraction is 13-15% and reclaim three in waste water
Chloropyridine sodium alkoxide, solid trichloro pyridyl sodium alcoholate is used for reproduction；
(2) waste water after reclaiming trichloro pyridyl sodium alcoholate adds quality and accounts for the hydrogen peroxide of waste water total amount 0.5%,
Pre-oxidation, preoxidation time is 7-9 hour；
(3) waste water after the pre-treatment adds the ferric chloride (FeCl36H2O) that consumption is waste water weight 0.1-0.15%
As catalyst, it is stirring evenly and then adding into high pressure reaction assembly, opens stirring, be warming up to 110-120 DEG C, and
It is incubated 6-8 hour；
(4) reaction cools the temperature to 35-45 DEG C after terminating, and opens emission-control equipment, slowly opens aeration,
Aeration time is 0.5-1 hour；
(5) continue cooling and sample, analyzing total phosphorus and the concentration of ammonia nitrogen, and put into successively according to concentration quantitatively
Magnesia and ammoniacal liquor, regulation pH value to 8.5, stir 10-13 minute, after standing filtration；
(6) salinity of the waste water after analytical reactions, according to concentration Low-salinity wastewater dilution to can be biochemical dense
Degree, qualified discharge after the microbial biochemical process that special type is cultivated；
(7) filter the solid produced indices after analyzing all to be up to state standards, be sold to available
Unit.
The processing method of a kind of chlopyrifos waste water, the mass fraction of described hydrogen peroxide is 30-35%.
The invention have the advantage that
The biodegrading process such as the degradation efficiency of organophosphor of the present invention is high, the general electrolysis of ratio, Fenton process are easier to
Up to standard；Phos after degraded is prepared as guanite, and indices therein has all reached country and utilized standard,
Produce a large amount of abraum salt waste organic matters than evaporation and decrease secondary pollution；After organophosphor is degraded, giving birth to of waste water
The property changed is greatly improved, and the indices of bio-chemical effluent all can meet discharging standards, meanwhile, and specific culture
Trichloro pyridyl sodium alcoholate in the basic degrading waste water of microorganism energy, in water outlet, trichloro pyridyl sodium alcoholate concentration is less than 1ppm,
After solar irradiation, waste water no longer reddens.
Detailed description of the invention
