| titleOfInvention | Method for disposing organochlorine pesticide POPs of lixivium in dangerous and polluted sites by utilizing modified attapulgite clay. |
| abstract | The invention relates to a method for disposing an organochlorine pesticide POPs of the lixivium in dangerous and polluted sites by utilizing modified attapulgite clay. The method comprises the following steps: pulverizing an attapulgite clay raw material to obtain attapulgite clay particles being larger than or equal to 300 meshes; conducting modification on the attapulgite clay particles after collection; firstly, conducting oxidization on the modified attapulgite clay particles with hydrogen peroxide aqueous; then, adopting acid for soaking and eluting till particles are weak acid; calcining at high temperature to obtain the modified attapulgite clay; grinding the modified attapulgite clay; making the modified attapulgite clay powder into modified attapulgite clay particlesr being approximately 20 meshes; fixing the modified attapulgite clay particles to form a dam body, of which the width is larger than or equal to 15 cm, with high permeable capability, wherein the dam body is arranged in radial-flow of the lixivium in dangerous sites of the organochlorine pesticide POPs or/and in the outflow route of leaching. Compared with the prior art, the method has the advantages that the operation is simple and easy, requirements for the equipment condition are low, the treatment efficiency is high, no by-products is generated, and harm, as well as the treatment cost, is low. The method is also applicable under high salinity and other extreme conditions, is efficient and energy-saving, and has an excellent application prospect. |
