The invention relates to an oil removal device based on modified magnetic particles, the oil removal device comprises a sewage tank for accommodating an oil-water mixture, the sewage tank is connected to a water purification tank through an oil removal chamber, a plurality of filtering guide plates and a post-filtering guide plate are sequentially arranged in the oil removal chamber from top to bottom, and the plurality of filtering guide plates are designed to form included angles with the horizontal plane. Filter elements are mounted on the plurality of filter flow guide plates, each filter element comprises a filter membrane, oleophylic and hydrophobic modified magnetic particles are coated in the filter membranes, and grid holes are formed in the plurality of filter flow guide plates. Compared with the prior art, the oil removal device can reliably carry out oil removal treatment and has the advantages of being environmentally friendly and low in cost.
Description
technical field [0001] The invention relates to the technical field of oily sewage treatment, in particular to an engineering degreasing device based on modified magnetic particles. Background technique [0002] In marine engineering, due to shipyard production or leakage, it is easy to cause a large amount of oily sewage to enter the sea, and a large part of the oil will float on the water surface to form an oil film. This oil film floats on the water surface for a long time and has a certain degree of airtightness. , if the oil film area is too large, it will seriously affect the marine underwater ecological environment. For this reason, most of the prior art adopt methods such as adsorption, combustion, biodegradation and various filter membranes to carry out degreasing and decontamination treatment. However, although the above-mentioned methods can achieve certain degreasing effects, these methods or the The material still has defects such as environmental pollution and...
