Abstract
The invention discloses a method for using a tea extract as an underwater organophosphorus pesticide chlorpyrifos treatment agent. The method comprises the steps of: placing a tea extract EGCG directly into sewage, using a high pressure mercury lamp to irradiate, adding a complexing agent into the sewage irradiated by the high pressure mercury lamp, and filtering out the generated precipitate. The treatment agent involved in the invention has the advantages of naturality, environmental protection, low dosage, convenient use and operation, low operation cost, high efficiency, low environmental pollution, wide application scope, no influence on running and operation of the system itself, stability under environmental condition change, no need for a special production process, direct preparation, and no harm to the human body and other living things, and can substantially save energy when it is used in optical processing technologies.
Description
Technical field
The present invention relates to remove the method for organophosphorus pollution Chlorpyrifos 94 from water.More specifically, the present invention relates to and use tea extract EGCG as treatment agent, remove the method for the organic pollutant Chlorpyrifos 94 of dissolving from water, method is applicable to the micro-pollution processing of tap water and production wastewater treatment.
Background technology
Organic phosphates replace of hypertoxic insecticides product Chlorpyrifos 94 (CP, Chlorpyrifos, O, O-diethyl-O-(3,5,6-trichloro-2-pyridyl) thiophosphoric acid) be one of insecticide variety of current produced worldwide and sales volume maximum, now, in 14 country's registrations such as China, the U.S., Australia, Japan and registration, registration kind reaches 1100.Although be the organophosphorus kind of the unique license of the World Health Organization, Chlorpyrifos 94 is to human nerve and all toxic effects of lung, especially higher to children's toxicity; Some biology as most hydrobionts are belonged to high toxic material, and organism in water enrichment factor reaches 100～5100.Use in a large number and make it comprise the delay in earth's surface fresh water and seawater in water surrounding, and caused the pollution of underground water, find to have in breast milk residual simultaneously.
To chlorpyrifos pollution, water treatment is usually directed to high-level oxidation technology at present, and the open chlopyrifos pesticides waste water treatment process of CN101172728 comprises the invention of the processing steps such as acid out, complexometric extraction, Fenton oxidation and catalyzed oxidation; CN102765850A invention relates to the treatment process of a kind of trichloro pyridyl sodium alcoholate and Chlorpyrifos 94 factory effluent, belongs to environmental technology field, comprises the processing steps such as evaporation, burning, biochemical process; CN102603094A invention relates to a kind for the treatment of process of Chlorpyrifos 94 factory effluent, and the step comprising has: pH value regulates, Fenton oxidation, neutralization, flocculation and filtration and charcoal absorption.Process is comparatively complicated.
In tap water, do not list separately organophosphorus insecticide cleanup standards such as trace Chlorpyrifos 94, conventionally utilize in the process of chlorination processing, by its oxidation.But in recent years, the investigation of the sickness rate to some cancer and etiology relation and a large amount of experimentation on animalies show, the tap water of long-term drinking chlorination, the danger of dying from digestion and urinary system cancer is very large, and chloro disinfection byproduct (DBP) is the virulence factor of kinds cancer.
(-)-NVP-XAA 723 is the anti-oxidant class material of natural polyphenol in tea, and extensive exploitation is for medicine, health care nutriment, food, makeup, even the field such as livestock and poultry cultivation.EGCG has the special construction of poly-hydroxy and phenyl ring, has water-solublely, does not find so far, to human body and other biological hazard, not have secondary pollution.
Summary of the invention
The object of the invention is just to provide a kind of method of cooing organophosphorus pesticide Chlorpyrifos 94 treatment agent in water of tea extract.
The present invention is achieved by the following technical solutions:
A method of cooing organophosphorus pesticide Chlorpyrifos 94 treatment agent in water of tea extract, comprises the following steps:
(1) tea extract EGCG is directly thrown in the sewage that contains organophosphorus pesticide Chlorpyrifos 94, the concentration that makes EGCG is 20-125 μ M, and regulating the pH of sewage is 4.6-7, and temperature is 20-30 DEG C;
(2) irradiate with the light source that waits the high voltage mercury lamp that is all 125-150W, the time is 10-12 minute;
(3) complexing agent is joined in the sewage after high voltage mercury lamp radiation, described complexing agent is Al
3+, Zn
2+, Fe
3+in one or more, concentration is identical with the concentration of the tea extract EGCG of above-mentioned interpolation, after precipitation to be generated, filter remove.
Advantage of the present invention is:
1, applied widely, this reagent not only can be applied to tap water, and also can have in contaminated underground water strange land and process, and all kinds of factory effluent, the processing of irrigation water.
2, the usage quantity that greatly reduces strong oxidizer in advanced oxidation processing, reduces light application time greatly, reduces energy expenditure.
3, treating processes is simple, there is no special equipment requirements.
4, meet environmental requirement, human body and environment are safe from harm.

Fig. 1 is photodissociation processing unit (1-light source; 2-reaction tank; 3-water inlet; 4-water outlet);
Fig. 2 is EGCG(25.0 μ M) processing Chlorpyrifos 94 (5.0 μ M) design sketch.
Embodiment
A photodissociation processing unit is as shown in Figure 1 for the treatment of Chlorpyrifos in Water Samples, water inlet Chlorpyrifos 94 concentration 5.0 μ M, and light source is high voltage mercury lamp, intensity 150W, in unit, hydraulic detention time is 10min, after this processing unit, in Chlorpyrifos 94 water, concentration is reduced to 2.0 μ M, reduces by 60%.Leave light source, the effect of EGCG can keep Chlorpyrifos in Water Samples concentration not raise in 48 hours, adds and the isocyatic Al of EGCG during this time
3+, Zn
2+or Fe
3+, generate complex compound sediment, after filtration, from water, remove Chlorpyrifos 94 completely.Cross and place for a long time or illumination again, and do not add Al
3+, Zn
2+or Fe
3+complex-precipitation is removed, and may make EGCG again discharge Chlorpyrifos 94.Treating processes power consumption 0.005WH/L.
EGCG(25.0 μ M) processing Chlorpyrifos 94 (5.0 μ M) effect.
EGCG(25.0 μ M) process Chlorpyrifos 94 (5.0 μ M) effect as shown in Fig. 2, after 10min illumination, Chlorpyrifos in Water Samples residual rate is 43.5 ± 0.8%.
