Abstract
The invention discloses a device and a method for repairing phthalate-polluted soil and underground water through a photoelectric Fenton principle, belonging to the field of the repair of soil and underground water. The method comprises the steps of arranging electrodes like an oval in the area at which the soil polluted by phthalate and arranging a central electrode at the position at which the concentration of the pollutant is the highest, wherein both the central electrodes and the outermost electrode are cathode electrodes, and the oval covers the whole polluted area. According to the device and the method, a traditional photoelectric Fenton method is improved; electrolyte solution and hydrogen peroxide are directly injected into the soil, and then a photoelectric Fenton system is directly established in the soil via Fe2+/Fe3+ produced on an anode and hydrogen peroxide produced at a cathode together with the poured electrolyte solution and the poured hydrogen peroxide; the surface of the soil is irradiated by using ultraviolet rays, so that the phthalate on the surface of the soil is thoroughly decomposed.

Description
Technical field
The invention belongs to soil underground water and repair the field, particularly a kind of photoelectricity Fenton (Fenton) is repaired the apparatus and method of phthalic acid lipid contaminated soil and underground water.
Background technology
Along with developing rapidly and the generally application of plastic products of plastics industry, phthalic acid ester enters into environment with the discharging of all kinds of sewage, thereby cause bed mud, soil, water body, air, biology and atmospheric falling dust thing generally to contain this pollutant, be called as immanent pollutant.According to reports, at human environment and natural environment all to detect existing of phthalic acid ester, remarkable as in the percolate of city, samll cities and towns and house refuse, detecting phthalic ester concentration, in soil, atmosphere, water body, biology even human body, all detect this organic existence.
Phthalic acid ester (Phthalic Acid Esters is called for short PAEs, the another name phthalate ester) is the chemicals that a class can play emollescence.It is widely used in hundreds of products such as toy, packaging material for food, Medical blood bag and sebific duct, vinyl flooring and wallpaper, cleaning agent, lubricating oil, personal-care supplies (such as nail polish, hair spray, perfumed soap and shampoo).The expert finds, the flexible plastic toy and the articles for children that contain phthalic acid ester might be put in the mouth by child, if the time long enough of placing will cause the stripping quantity of phthalic acid ester to surpass level of security, children's liver and kidney can be endangered, also children's sexual precocity can be caused.European Union just formally maked decision in 1999, and in EU member country, the content of phthalic acid ester strictly limits in the toy that contacts with mouth (such as baby nipple) that children below 3 years old are used and other articles for children.European Union forbids or limits 6 kinds of phthalic acid esters of use in toy for children and goods.
Phthalic acid ester is the important organic compound material of a class, common are repefral (DMP), diethyl phthalate (DEP), n-butyl phthalate (DBP), di-n-octyl phthalate (DOP), diisooctyl phthalate (DEHP) and butyl benzyl phthalate (BBP).The cruel general chemistry structure of phthalic acid is comprised of two parts, a rigid plane aromatic ring and two plastic non-linear aliphatic side chainses, and photodissociation and hydrolysis rate are all very slow under field conditions (factors) for they.Phthalate ester is in vivo enrichment easily, and acute toxicity intensity is little, but animal is had mutagenesis and teratogenesis.Phthalic acid ester is connected with the TPO plastic molecules by hydrogen bond or Van der Waals force, is diffused in the external environment in the use procedure of plastics, and is enriched in by all means upper soll layer and inside.
