Description
Technical field
The invention belongs to agricultural chemicals waste water processing technology field, a kind of agricultural chemicals waste water dephosphorization agent is concretely related to.
Background technology
According to《Organophosphorus insecticide industrial water pollution thing discharge standard》, existing 2000 Duo Jia pesticide producings enterprise of China, its
The pesticide producing enterprise that middle National Development and Reform Committee has issued licence is just up to 1765.In recent years, China's pesticide industry quickly grows, annual capacity
Power has reached l50 more than ten thousand tons, and total output occupies first place in the world, and is main agricultural chemicals exported country, and wherein organophosphorus pesticide accounts for major part.
China's organophosphorus pesticide industry is one of most heavy department of ambient pollution burden in chemical industry, is also dirty in Fine Chemical
Dye difficulty of governance is big, put into most industries.Because expansion is rapid, kind and the reason, China's organophosphorus pesticide such as backward in technique
Produce and become increasingly conspicuous using the health, environmental problem brought.In organophosphorus pesticide production process, the wastewater flow rate of generation is big, COD
Height, salt content is high, and total phosphorus content is high, and in the technique waste water that production process is produced, total phosphorus is up to more than 3000mg/L (in terms of P).
Current each enterprise be substantially by its with other waste water mixed dilutings after, into after biochemical treatment apparatus treatment, total phosphorus content is average
Reach 80mg/L or higher (wherein about 70% above is phosphate), substantially dilution discharge.It is heavy except indivedual Enterprise Constructions
Form sediment in addition to phosphatic device, other enterprises are all without dephosphorization apparatus.Therefore, some enterprises even face and are forced closure, suspension, merger and conversion
Condition, organophosphorus pesticide wastewater dephosphorization is still the outstanding problem for influenceing pesticide industry development.Adsorb organic with adsorbent at present
The report of organophosphor is many in phosphorus agricultural chemicals waste water, such as activated carbon, mineral, trade waste.These adsorbents are in pure system
The adsorption effect of organophosphor is very high, but the salt coexisted in waste water substantially reduces its absorption property.
For the treatment of agricultural chemicals waste water, at present, the existing many patents in the country, but most of concentrate on Phos agricultural chemicals
Waste water.Existing phosphorous removing agent for wastewater produced during producing organophosphorus prepares difficulty mostly, and dosage is big, and dephosphorization efficiency is not high, and is used for place
Reason low concentration wastewater.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of agricultural chemicals waste water dephosphorization agent, are treated by the dephosphorization agent
Waste water, more can thoroughly remove the phosphorus containg substances in agricultural chemicals waste water, waste water is reached standard requirement.
To achieve the above object, technical scheme to be solved by this invention is：
The present invention provides a kind of agricultural chemicals waste water dephosphorization agent, is made up of the raw material of following weight portion：20~50 parts of molysite, sulfuric acid
10~30 parts of aluminium, 8~25 parts of Boratex, 6~18 parts of ethylene-acetic acid ethyl ester, 3~16 parts of tannin.
Preferably, agricultural chemicals waste water dephosphorization agent of the present invention, is made up of the raw material of following weight portion：Molysite 25~45
Part, 15~25 parts of aluminum sulfate, 12~21 parts of Boratex, 8~16 parts of ethylene-acetic acid ethyl ester, 5~13 parts of tannin.
It is highly preferred that agricultural chemicals waste water dephosphorization agent of the present invention, is made up of the raw material of following weight portion：35 parts of molysite,
20 parts of aluminum sulfate, 16 parts of Boratex, 12 parts of ethylene-acetic acid ethyl ester, 9 parts of tannin.
It is highly preferred that agricultural chemicals waste water dephosphorization agent of the present invention, is made up of the raw material of following weight portion：25 parts of molysite,
25 parts of aluminum sulfate, 12 parts of Boratex, 16 parts of ethylene-acetic acid ethyl ester, 5 parts of tannin.
Preferably, molysite of the present invention is in bodied ferric sulfate, ferrous sulfate, ferric sulfate, iron chloride, poly-ferric chloride
One or more.
It is highly preferred that molysite of the present invention is the mixture of bodied ferric sulfate and iron chloride.
It is highly preferred that molysite of the present invention is bodied ferric sulfate and iron chloride weight ratio is 3:5 mixture.
In the processing procedure of agricultural chemicals waste water, be most difficult to accomplish is the degraded to organophosphor, and the present invention is using preparation method wound
New design Novel dephosphorization agent, analyzes the characteristic and phosphatic form of waste water, for Phos, the nature difference of organophosphor,
The optimal reagent combination of screening, collection efficiently complexing is formed using iron molysite, aluminum sulfate, Boratex, ethylene-acetic acid ethyl ester, tannin
Organophosphor in agricultural chemicals waste water is first converted into Phos by agent, oxidant, adsorbent and flocculant in the compound drug of one, then
Phos is changed into precipitation or complex compound by absorption, flocculation, improve the treatment effect of organophosphorus pesticide wastewater, significantly
Reduce agricultural chemicals waste water total phosphorus content.
Agricultural chemicals waste water dephosphorization agent simple production process of the invention, it is only necessary at a temperature of 40~50 DEG C, stirs 30
~50min, low production cost.
The features such as present invention has relatively low cost of investment, economic operating cost, produces sludge quantity less, by dephosphorization of the present invention
Agent can reach more than 99.2% to total phosphorus removal effect in organophosphorus pesticide wastewater.The present invention is steady for what pesticide industry was produced
Surely run significant.
