Abstract

PURPOSE:To easily fix a small amount of oil and to prevent the diffusion of a bacteria decomposition accelerator and petroleum decomposing bacteria to an aqueous system by supporting bacteria nutrients and/or petroleum decomposing bacteria on a gelling agent. CONSTITUTION:An oil treatment agent can be obtained by usually supporting 0.5-5wt.% of bacteria nutrients and/or 10-40wt.% of petroleum decomposing bacteria on 60-90wt.% of a gelling agent. This oil treatment agent is extremely effective as the treatment agent of oil cast away on the seaside. The gelling agent is prescribed in use as a chemical agent used in order to prevent sea pollution due to oil or a harmful liquid substance. The bacteria nutrients consist of phosphorous nutrients and nitrous nutrients. As petroleum decomposing bacteria, there are bacteria belonging to the genus Pseudomonas and these petroleum bacteria are mixed with sawdust or clay to be improved in storage stability.

2. Description of the Related Art In modern times, petroleum is indispensable as energy and raw material, and its consumption has increased with the development of industry. As a result, marine pollution due to oil and the like has become more frequent, causing various forms of damage. As described above, the oil spill phenomenon or damage caused by oil spill is one of the important and environmental problems to be solved in modern times. Conventionally, when spilled oil occurs,
There are (1) a method of covering with an oil fence, (2) a method of mechanically collecting with an oil recovery ship or a recovery device, and (3) auxiliary means (a) oil adsorbents, histories, etc. as needed. (B) Oil treatment agent (oil is made into fine particles and dispersed in the sea area by an emulsifier etc.)
Is used together with (c) gelling (floating) oil with a gelling agent to recover (solid), and the rest depends on the natural purification capacity. Is the current situation. In natural purification, petroleum decomposition by microorganisms plays a major role, and it is the action of these microorganisms that ultimately purifies petroleum regardless of physicochemical removal or treatment. is there. Recently, in order to maximize the ability of microorganisms that are deeply involved in natural purification, "microorganism decomposition promoters (nutrient salts)" and "microorganisms with high petroleum decomposing ability" (petroleum degrading microorganisms) are sprayed in oil-polluted waters. Attempts are being made. Oil spilled into the ocean due to an accident,
At first, it undergoes physicochemical changes such as evaporation and dissolution, but this process ends relatively quickly, and then it is purified by the process of decomposition and removal by microorganisms. Factors affecting the microbial decomposition process of petroleum released to the ocean are (1) seawater temperature, (2) density of petroleum-degrading microorganisms, (3) concentration of nutrient salts, and the like. The seawater temperature cannot be controlled because it is possible. On the other hand, although there are petroleum-degrading microorganisms in the oil-polluted area, the rate of microbial decomposition of petroleum is very slow due to the low concentration of inorganic nutrient salts such as nitrogen and phosphorus. Therefore, in order to promote the decomposition of petroleum degrading microorganisms in the ocean, it is effective to spray the petroleum degrading microorganisms in order to efficiently increase the density of the inorganic nutrient salts and the petroleum degrading microorganisms. As a conventional microbial decomposition accelerator, (1) water-soluble inorganic salt,
(2) Finely divided solid nutrient powder, a mixture of white beeswax and N-paraffin, which is microencapsulated to make it lipophilic. (3) Consists of water, urea, oleic acid, ethylene glycol butyl ester, and lauryl phosphate. Microemulsion (This is a fine water droplet containing nitrogen source and phosphorus source in the oil layer when sprayed on the oil layer)
The conventional petroleum-degrading microorganisms are used in the form of microbial preparations fixed on sand or sawdust.

The problems of the prior art relating to the removal and recovery of oil spills floating or drifted ashore are: (1) Recovery of a small amount of oil after physical recovery is completed. Is difficult, (2) even if a microbial decomposition accelerator or petroleum-degrading microorganism is sprayed, it diffuses into the water system, (3) oil that enters under the rocks on the coast or oil that becomes oil balls and settles on the seabed The point is that they cannot be collected. Therefore, an object of the present invention is to eliminate these problems. That is, it is to provide a novel oil treatment agent which can easily fix a small amount of oil and prevent the diffusion of a microbial decomposition accelerator or a petroleum-degrading microorganism into an aqueous system.

[Effect] By using the oil treatment agent containing this gelling agent, the following effects are obtained. (1) Solidify a small amount of oil floating in the ocean to facilitate recovery. (2) The oil leaked and recovered is easily decomposed in the natural world no matter where it is washed ashore or accumulated because the nutrients and petroleum-degrading microorganisms are attached to the oil. (3) Solidify a small amount of oil adhering to rocks and sand on the coast to facilitate recovery. (4) If the spilled oil or stranded oil is once solidified by the gelling agent and loses its fluidity, it will not settle in the ocean and the oil can be prevented from soaking into the sand or rocks at the coast. (5) By fixing the oil to the rocks and sand on the coast, it is possible to prevent the oil from flowing into the sea. (6) Since the nutrient salt gradually flows out from the gel containing the nutrient salt adhering to the rocks and sand on the coast, nutrients can be supplied to the microorganisms in the vicinity for a long period of time, and the decomposition of oil can be promoted. Among them, the treating agent of the present invention is most suitable for treating stranded oil on the coast.
