Abstract
This invention discloses a method for preparing and utilizing tealeaf powder for treating wastewater polluted by polycyclic aromatic hydrocarbons. The method comprises: (1) collecting tea residues or old tealeaves, soaking in 80-90 deg.C water bath for 48 h, and washing with tap water for 3 times to remove the water-soluble ingredients; (2) air-drying the treated tealeaves at room temperature, placing in an oven, and baking at 110-120 deg.C for 3-4 h; (3) grinding the baked tealeaves, and sieving with 10-100 mesh sieve to obtain tealeaf powder; (4) adding the tealeaf powder into wastewater polluted by polycyclic aromatic hydrocarbons (0.1-5 g/L), mixing uniformly, and vibrating for more than 24 h to remove polycyclic aromatic hydrocarbons. The method is simple. The prepared tealeaf powder has a good treatment effect on wastewater polluted by polycyclic aromatic hydrocarbons.
Description
Technical field
The present invention relates to a kind of tea-leaf power preparation and using method of handling waste water polluted by polycyclic aromatic hydrocarbon.
Background technology
China's shortage of water resources, water pollution especially organic contamination are on the rise.Though biochemical treatment process commonly used can reduce COD amount in the waste water largely in the municipal sewage treatment, covered the harm of material that " three causes (carcinogenic, teratogenesis shape, mutagenesis) " such as polycyclic aromatic hydrocarbons wherein or highly toxic substance to ecology.For these lower concentrations, difficult biochemical pollutent generally is to remove by technologies such as coagulating sedimentation, chemical oxidations.Coagulating sedimentation is relatively poor to deliquescent Persistent organic pollutants removal effect; Chemical oxidation has selectivity to hardly degraded organic substance, and the processing cost height, is not suitable for handling the town sewage that has a large capacity and a wide range.Therefore, the adsorption treatment method of Persistent organic pollutants has been subjected to various countries environmentalists' extensive concern too in the sewage.Absorption method is to remove the effective ways of Persistent organic pollutants, and wherein most critical is the exploitation high-efficiency adsorbent.
Tealeaves is one of soft drink of global consumption maximum, and a year consumption can reach more than 300 ten thousand tons.Tea grounds after making tea is generally included domestic refuse in and is handled.In addition, every year all need be repeatedly pruned tea tree in the tea place, and the tealeaves of pruning is often discarded by the tea grower based on Lao Ye.These depleted tea grounds and Lao Ye not only cause environmental pollution easily, also are a kind of wastings of resources.Studies show that pore is many in the tealeaves, surface-area is big, can absorb peculiar smell, stink, can be used as reodorant and uses.Organic carbon content height in the tealeaves, generally greater than 50%, in theory should strong adsorption organic pollutant, especially those fat-soluble big persistence organic pollutants.Given this, the present invention has developed the persistence toxic organic pollutants such as polycyclic aromatic hydrocarbons that a kind of tea-leaf power is used for adsorption treatment waste water.
Summary of the invention
The purpose of this invention is to provide a kind of tea-leaf power preparation and using method of handling waste water polluted by polycyclic aromatic hydrocarbon.
The preparation method of tea-leaf power capable of handling waste water polluted by polycyclic aromatic hydrocarbon comprises the steps:
1) collect tea grounds or tea tree ' s old leaf, be placed in 80~90 ℃ the water bath with thermostatic control and soak more than 48 hours, and then with the tap water flushing more than 3 times, to remove water soluble component in the tealeaves;
2) will after at room temperature drying, the tea grounds of above-mentioned processing or tea tree ' s old leaf put into baking oven, 110~120 ℃ of bakings 3-4 hour down;
3) tea grounds after will drying or tea tree ' s old leaf 10~100 mesh sieves of milling obtain tea-leaf power.
The tea-leaf power using method of handling waste water polluted by polycyclic aromatic hydrocarbon is: the mass volume ratio by 0.1~5g/L adds tea-leaf power in the waste water polluted by polycyclic aromatic hydrocarbon, and the mixing vibration can effectively be removed the polycyclic aromatic hydrocarbons in the waste water more than 24 hours under the room temperature.
Making method of the present invention is simple, raw materials used is depleted tea grounds or tea tree ' s old leaf, belong to recycling of waste resources, the tea-leaf power that makes is good to the treatment effect of polycyclic aromatic hydrocarbons, can promote the use of in poisonous organic pollution field of waste water treatment such as polycyclic aromatic hydrocarbons.
