DETAILED DESCRIPTION - The device comprises a reactor body having a circular bottom, a water inlet on left wall of the body, a water outlet on the right wall of the body, and left and right brackets fixed respectively at a top of the reactor body. The turntable frame is made of stainless steel. The frame comprises a support shaft and a rotating shaft in a same plane. A fixing bracket and a porous adsorption plate are installed on the upper part of the frame. The porous absorption plate is prepared by: mixing 100 ml of ammonium dihydrogen phosphate having concentration of 0.62 mole/l and 100 ml of ammonium hydrocarbonate having concentration of 0.35 mole/l uniformly to obtain a mixture (A1); adding ammonium hydroxide solution having concentration of 0.01 mole/l and hydrochloric acid solution having concentration of 0.01 mole/l to mixture (A1) to adjust pH of the mixture to be 9 to prepare mixture (B); slowly adding 200 ml of mixture B dropwise to 300 ml of calcium nitrate solution having concentration of 0.025 mole/l to obtain a mixture (B1) under stirring; adding the mixture (B1) to clear concentrated nitric acid dropwise to obtain mixture (C1); adding sodium hydroxide solution having concentration of 0.01 mole/l and hydrochloric acid solution having concentration of 0.01 mole/l to mixture (C1) to adjust the pH value of the mixture (C1) to be 3.5 to obtain mixture (D); adding 100 ml of ammonium chloride aqueous solution having concentration of 1.1 mole/l to the mixture (D); uniformly mixing the mixture to obtain mixture (E); adding 50ml of solution of potassium and calcium edetate having concentration 0.15 mole/l to the mixture (E); uniformly mixing the mixture to obtain a mixture (F); adding 200 ml of styrene chloroform solution having mass fraction of 11.5%; mixing 40 ml of azobisisobutyronitrile chloroform solution having mass fraction of 9.5 wt.% and divinyl benzene chloroform solution having mass fraction of 1.5 wt.% to obtain mixture (G); adding 60 ml of mixture (F) to mixture (G) at 1000 revolutions per minute dropwise; stirring at revolutions per minute for 8 minutes to obtain mixture (h); injecting distilled water into a container equipped with liquid nitrogen; adding the mixed solution (h) into a mold; shaping for 6 hours; freezing and drying to remove chloroform and phosphorus element of the adsorption plate; and placing the absorbing plate in a petroleum hydrocarbon biodegradation bacterium culture solution for 24 hours having bacteria amount of 5x 1010 colony forming units/ml, where the culture solution comprises 2 g.L-1 of ammonium nitrate, 10.5 g.L-1 of sodium chloride, 2.5 g.L-1 of potassium phosphate, 0.10 g.L-1 ferrous chloride, 3.5 g.L-1 of magnesium sulfate, and 0.15 g.L-1 of calcium chloride.
