NOVELTY - A hard degradable wastewater is treated by selecting strain, providing liquid culture medium, providing carrier material, providing carrier envelop, and performing treatment process. The selection of strain includes providing Phanerochaete chrysosporium, and Trametes versicolor. The treatment process includes providing treating water sample preferably abamectin water; regulating original pH, and adding carriers, white-rot fungi, and water sample to taper bottle; and putting into shaking table, and changing water in reactor to continuously carry out treatment.    USE - Method for treating hard degradable wastewater (claimed).    ADVANTAGE - The method only needs to regulate original pH, where intermediate process needs no operation and no regulation again; and can carry out subsequent treatment. The carrier has wide availability of raw material source. The carrier is directly used as fertilizer together with thalli, with no secondary pollution. The treated wastewater has a notable decolorization effect, where decolorization rate is more than 90%.    DETAILED DESCRIPTION - The hard degradable wastewater is treated by selecting strain, providing liquid culture medium, providing carrier material, providing carrier envelop, and performing treatment process. The selection of strain includes providing Phanerochaete chrysosporium(CICC 40719), and Trametes versicolor (CICC 50001) purchased from strain collection center. The provision of liquid culture medium involves:    (A) providing potato extracted powder and yeast culture medium, where potato extracted powder can be white-rot fungi which has strong adaptability for environment, and yeast culture medium can be mycelium pellet with small grain diameter and strong degradation ability;    (B) cooling, inoculating 0.05 g of white-rot fungi; putting into shaking table at 28-34 degrees C and 170 rpm;    (C) culturing for 3 days, where potato extracted powder comprises potato extracted powder (4 g/100 ml), glucose (2 g/100 ml), dipotassium phosphate (0.3 g/100 ml), and magnesium sulfate (0.15 g/100 ml); and yeast culture medium comprises glucose (0.5 g/100 ml), potassium dihydrogen phosphate (0.1 g/100 ml), ammonium sulfate (0.1 g/10 ml), magnesium sulfate pentahydrate (0.05 g/100 ml), yeast extract (0.02 g/100 ml), at pH 5.0-6.0; and    (D) putting liquid culture medium into 250 ml of taper bottle, and sterilizing for 20 minutes at 121 degrees C.    The provision of carrier material involves selecting natural substances as core material of carrier including corn straw and gaseous corn straw; using 3% sodium hydroxide to dip straw for 30 minutes; using clear water to wash, and using 3% sulfuric acid to dip for 30 minutes; using clear water to wash until it is neutral; using 75% industrial alcohol to dip for 30 minutes; filtering, putting into oven at 50 degrees C, and drying for 5-6 hours; and sterilizing for 15 minutes at 121 degrees C. The provision of carrier envelop providing carrier containing 0.3 g of natural substance; using copper net and iron wire net to envelop core, where copper net is 1.8 plus minus 0.2 g, and iron wire net is 1.1 plus minus 0.2 g; and using nylon net to cover. The treatment process includes providing treating water sample preferably abamectin water; regulating original pH of wastewater to 4-5.5, adding 3 carriers, white-rot fungi (0.3-0.5 g), and water sample (100 ml) to taper bottle (250 ml); putting into shaking table at 35-60 degrees C and 170 rpm; and preserving deposition, and changing water in reactor to continuously carry out treatment.
