Experimental device for underground two-dimensional elevation sandiness mud flat petroleum pollution

Abstract

The invention belongs to an equipment manufacturing technology in the field of beach petroleum pollution and remediation, and relates to an experimental device for underground two-dimensional elevation sandiness mud flat petroleum pollution. Various pressure measurement tubes arranged on a pressure measurement raft are connected with sand soil sampling holes; seawater level measurement holes are communicated and connected with the pressure measurement tubes in the pressure measurement raft; a seawater storage tank evacuation tube valve is arranged on one side of the bottom of a seawater storage tank; the upstream tank bottom of a first overflow partition plate arranged in the middle of a seawater level adjustment tank is connected with a water inlet hose; the downstream tank bottom is connected with an overflow tube; a first self-locking gear rack elevator is arranged on the left side face of an elevation steel framework tank body; the upstream tank bottom of a second overflow partition plate arranged in the middle of an underground water level adjustment tank is connected with an overflow region water outlet end vertical shaft; the downstream tank bottom is connected with an underground percolation water outlet overflow tube; a gravimetric method measurement water tank is placed on an electronic platform scale; and the lower end of a wave paddle is fixedly mounted on a bearing fixed bracket on the inner side of a left elevation dismountable door plate. The device is reasonable in structure, simple to operate, easy to manufacture and grasp, and flexible to control and adjust.

Description

Technical field: [0001] The invention belongs to the equipment manufacturing technology in the field of beach oil pollution and restoration, and relates to a two-dimensional oil pollution experimental device on the underground facade of sandy tidal flats, which is used for studying the adsorption and release process of oil pollutants in marine tidal flats and the microbial degradation and degradation of oil pollutants. For scientific issues such as bioremediation technology, more accurate technical solutions and applicable experimental methods and devices are provided. Background technique: [0002] Oil pollution is one of the most concerned marine environment and ecological problems in the world. Due to the exploration, exploitation, refining of offshore oil and the development of related industries, the traffic on the sea is busy, and oil spill accidents occur from time to time, causing a large number of Oil goes into the ocean. According to statistics, about 3.2 million ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art, seek to design a two-dimensional oil pollution experimental device for the underground facade of sandy tidal flats, and solve the problems of two-dimensional facades, waves, ground precipitation, and sea water levels that cannot be considered in conventional experimental techniques. It provides accurate technical experimental equipment for the study of the adsorption and release process of oil pollutants in ocean tidal flats, as well as the microbial degradation and bioremediation of oil pollutants.
