Document Type and Number:
WIPO Patent Application WO/2020/124728
Kind Code:
A1
Abstract:
The present application relates to the technical filed of groundwater remediation, and in particular, to an emulsified vegetable oil and a preparation method therefor and an application thereof. The emulsified vegetable oil comprises the following components in percentage by weight: 45%-75% of edible vegetable oil, 2%-12% of a surfactant, and 20%-45% of water, and also comprises an optionally common substrate and/or pH regulating agent. The preparation method for the emulsified vegetable oil comprises the steps of mixed dissolution of soluble substrates, oil-water mixing and stirring and the like; the application method for the emulsified vegetable oil comprises the steps of injection well construction, emulsified oil use liquid preparation, indigenous microorganism activity evaluation, emulsified oil use liquid injection and the like, thereby realizing up-to-standard remediation of underground water polluted by a chlorinated organic compound. After being injected, the emulsified vegetable oil prepared in the present application can quickly work and is stable and lasting, and one-injection can continuously work for 3 to 5 years, without constantly continuously adding the emulsified vegetable oil. The method in the present application is reasonable in process, easy to obtain raw materials, low in costs and easy to popularize and implement, and has good environmental benefits, economic benefits, and social benefits.
