Problems solved by technology

[0004] In view of the inconvenience caused by the need for recovery and separation after the absorption and saturation of the existing high oil-absorbing resin, the purpose of the present invention is to provide a microbial-loaded resin adsorbent that can degrade oil stains. The resin adsorbent is loaded with microorganisms that degrade petroleum. The adsorbed oil can be degraded, so that it can be used for a long time, avoiding the recovery and separation of the adsorbed oil, and the adsorption capacity is large and the adsorption rate is fast

Abstract

The invention relates to the technical field of remediation of oil-overflowing water bodies and particularly relates to a microorganism loading type resin adsorbent capable of degrading greasy dirt and a preparation method of the resin adsorbent. The resin adsorbent is prepared by the steps of dipping a microorganism loading body into an acrylate copolymer emulsion, and drying, wherein the microorganism loading body is prepared by loading a multi-channel carrier particle with petroleum hydrocarbon degrading bacteria, and the carrier particle is a konjac glucomannan aerogel particle. The resinadsorbent is capable of degrading adsorbed petroleum and continuously treating petroleum in water; konjac glucomannan aerogel is loaded with petroleum hydrocarbon degrading bacteria and is embedded into acrylate resin, so that the curing stability of a strain is high; and konjac glucomannan aerogel and acrylate resin are internally provided with rich micro-fine channels, so that the resin adsorbent has huge oil absorption capacity and is high in adsorption velocity.

Description

technical field [0001] The invention relates to the technical field of oil spilled water restoration, in particular to a microbial-loaded resin adsorbent capable of degrading oil stains and a preparation method. Background technique [0002] In the past few decades, my country's industry has developed rapidly, and the living standards of the people have also continued to improve. However, with the development of industrialization, the demand for oil has also increased year by year, but it is inevitable in the process of oil exploration, mining, transportation, refining, and use. The land pollutes the air, surrounding soil, water sources, etc., especially offshore oil exploitation, oil spills from oil tankers, oil spills caused by oil tanker accidents, and random discharge of untreated oily industrial wastewater can cause oil spills at sea, bringing Serious marine oil pollution. Substances such as p-xylene and polycyclic aromatic hydrocarbons in petroleum are toxic and carcino...
