NOVELTY - A high-salt low-phosphorus organic chemical wastewater fixed adsorption tube reactor comprises movable cover, water inlet, pneumatic valve, mounting plate (4), fixing plate (5), water outlet, reactor main body (7), multifunctional adsorption tube (8) and base (9). Multifunctional absorption tube is prepared by mixing ammonium bicarbonate and monoammonium phosphate, adjusting pH, mixing styrene, divinylbenzene and azobisisobutyronitrile, mixing solutions, adding distilled water, freezing, casting, pressing, removing mold, freeze-drying, culturing bacteria, fixing on adsorption tube, and drying.    USE - High-salt low-phosphorus organic chemical wastewater fixed adsorption tube reactor.    ADVANTAGE - The reactor has short processing time, high efficiency, low cost, and simple operation.    DETAILED DESCRIPTION - A high-salt low-phosphorus organic chemical wastewater fixed adsorption tube reactor comprises movable cover, water inlet, pneumatic valve, mounting plate (4), fixing plate (5), water outlet, reactor main body (7), multifunctional adsorption tube (8) and base (9). Multifunctional absorption tube is prepared by:    (A) taking 100 mL 0.35 mol/L ammonium bicarbonate solution and 100 mL 0.62 mol/L monoammonium phosphate, mixing, and adjusting pH value to 9.0 using ammonium hydroxide and hydrochloric acid;    (B) adding 300 mL 0.025 mol/L calcium nitrate solution, stirring slowly, and adding concentrated nitric acid to clarify;    (C) adjusting pH value to 3.5 using ammonium hydroxide and hydrochloric acid, adding 100 mL 1.1 mol/L ammonium chloride solution, mixing, adding 50 mL 0.15 mol/L EDTA calcium salt solution, and mixing;    (D) adding 200 mL 11.5 wt.% styrene chloroform solution, 40 mL 9.5 wt.% divinylbenzene chloroform solution and 40 mL 1.5 wt.% azobisisobutyronitrile chloroform solution, and mixing;    (E) mixing solutions at speed of 1000 revolutions/minute for 8 minutes, adding distilled water, flash freezing in liquid nitrogen, and sieving to particle size of 50-100 mu m;    (F) placing in tubular die cavity, pressing, pouring liquid, freezing for 6 hours, removing mold, and freeze-drying; and    (G) preparing culture medium, culturing petroleum hydrocarbon degrading bacteria for 24 hours, fixing on adsorption tube, and drying.    Culture medium contains 2.0 g/L ammonium nitrate, 10.5 g/L sodium chloride, 2.5 g/L monopotassium phosphate, 0.10 g/L ferric chloride, 3.5 g/L magnesium sulfate and 0.15 g/L calcium chloride dihydrate.
