Problems solved by technology

[0002] Most of the existing simulation devices for marine oil spill experiments are carried out in cube reaction tanks. The equipment is too simple to simulate the coastline, especially the situation of beach oil spills
Although a large number of microorganisms that can degrade petroleum have been found in previous experimental studies, and the experimental results in the laboratory are relatively satisfactory, but the actual application results are not very satisfactory.

Embodiment 1

[0013] see figure 1 , a bioremediation device for simulating beach oil spills, mainly composed of a cylinder body 11, a partition plate 3, a right thermometer 4, a left thermometer 5, a wave maker 6, a temperature control device 7 and a lighting device 8, and two sides of the bottom of the cylinder body 11 are arranged There is a right water outlet 1 and a left water outlet 9, and correspondingly provided with a right water valve 2 and a left water valve 10, and a detachable partition 3 is arranged in the middle of the cylinder to separate the cylinder 11 into two spaces on the left and right , the left thermometer 5 and the right thermometer 4 are respectively installed on the left and right sides of the cylinder body, the readings of the thermometers can be observed from the outside, and the detachable VP-201 artificial wave maker 6 is installed on the right side of the cylinder body 11, and the wave maker 6 passes through The suction cup holds the inner wall of the cylinder...

Embodiment 2

[0015] (1) Bacterial source sample acquisition:

[0016] Water samples are collected in sterile blue-necked bottles of about 500ml of water samples in the static water layer. Sludge samples are collected from the surface of oil sludge about 0.5-1.0kg and placed in sterile containers. All samples should be enriched within 24 hours. Collected culture or sealed storage at 4 ℃.

[0017] The study found that the marine oil pollution occurred and the surrounding areas where marine oil pollution accidents occurred before are rich in resources of oil pollution degrading bacteria, and these bacteria bear the heavy responsibility of eliminating marine oil pollution. The bacteria source screening samples of the present invention come from oily waste water and sludge produced after cleaning ships at Zhoushan Wharf. These wastes contain high salinity and a layer of oil slick floats on the upper layer.

[0018] (2) Bacteria enrichment:

[0019] Take 10ml of water sample and 0.5g of sludge...

Abstract

The invention provides a device for simulating biological repair of sea beach oil spill. The device is mainly composed of a cylinder body, a clapboard, left and right temperature gauges, a wave forming device, a temperature control device and a lighting device, wherein water pipe ports are arranged on two sides at the bottom of the cylinder body and are correspondingly provide with left and rightwater valves; the clapboard is arranged in the middle of the cylinder body and divides the cylinder body into two spaces; the left and right temperature gauges are respectively installed at left and right sides of the cylinder body; the artificial wave forming device and the temperature control device are installed at the right side of the cylinder body and are sucked to the inner wall of the cylinder body through sucking discs; and the lighting device is installed at the upper part of the cylinder body. The device has reasonable design and low cost, and is simple to prepare; and the device can be used for rapidly simulating biological oil spill repair conditions, can also be used for rapidly culturing and acclimatizing petroleum degrading flora, and has high efficiency and good effect ascompared with a common cubic aeration pool.

Description

technical field [0001] The invention belongs to a microbial oil degradation reactor, in particular to a device for simulating beach oil spill bioremediation. Background technique [0002] Most of the existing simulation devices for marine oil spill experiments are carried out in cube reaction tanks. The equipment is too simple to simulate the coastline, especially the situation of beach oil spills. Although a large number of microorganisms that can degrade petroleum have been found in previous experimental studies, and the experimental results in the laboratory are relatively satisfactory, but the actual application results are not very satisfactory. [0003] Therefore, it is of great significance to provide a pilot test device in this study to simulate the beach oil spill bioremediation conditions as much as possible. Contents of the invention [0004] The object of the present invention is to provide a kind of bioremediation device for simulating beach oil spill, throug...
