Abstract

The invention discloses a two-phase flowing biological bed based on composite oil removal bacteria. According to the two-phase flowing biological bed, fixed plates parallel to the bottom of an aerobicpool are arranged in the aerobic pool; the fixed plates are provided with gas holes for passing through of gas; the adjacent fixed plates are filled with aerobic filler blocks; an aeration device isarranged below the fixed plates; and the aerobic filler blocks are internally provided with a mixture of an active carrier, a composite oil removal bacterial agent and a nutrition agent thereof, wherein the active carrier is 20-40 parts of modified active carbon fiber, the composite oil removal bacterial agent comprises a plurality of bacteria selected from bacillus, yeast and micrococcus, and thenutrition agent is prepared from 2 to 6 parts of uric acid, 1 to 6 parts of phosphate, 8 to 16 parts of glucose, 0.4 to 1.2 parts of arachidonic acid, 0.3 to 0.9 part of sucrose polyester and 1 to 4parts of magnesium sulfate. According to the invention, the strain changes the hydrophobicity of the surface of the strain by releasing surface active substances on the surface of the strain, so thatthe strain is easily attached to the surfaces of hydrocarbon substances.

Description

technical field [0001] The invention belongs to the technical field of oil-removing bacteria for treating oily sewage, in particular to a two-phase flow biological bed based on compound oil-removing bacteria. Background technique [0002] With the development of human society and the acceleration of industrialization, some marine environments have been polluted and destroyed, even endangering human health. Sea transportation has the advantages of low cost and large transport tonnage, so 60% of the world's total oil production is transported by ships. With the rapid development of shipping, part of the oil enters the marine environment with the ballast water of cruise ships, oil tank washing water and engine room bilge water of other ships during the voyage, reaching 500,000 to 1 million tons per year. Marine environmental pollution incidents have 35% were due to pollution from ships. The oily substances leaked into the ocean have had a serious impact on the marine environm...
