The filter membrane be two-dimensional ultrathin nickel hydroxide nano thin-film material, preparation method be by 40 parts of Nickel dichloride hexahydrates, In the mixed solvent, which is added to, after 55 parts of urea mixing is heated to 50- after magnetic agitation 30-60min is completely dissolved to reaction raw materials At 60 DEG C, heat preservation after twenty minutes, continues to heat reaction mixture temperature to 85-95 DEG C, persistently stirs insulation reaction after sixty minutes, Reaction product is centrifugated by cooled to room temperature, and filter cake is centrifuged repeatedly processing 2 times again after being washed with dehydrated alcohol, will be filtered Cake obtains nickel hydroxide ultrathin nanometer film after spontaneously drying at room temperature;
The mixed solvent is the mixture of water, methanol and ethyl alcohol, and wherein the volume ratio of water, methanol and ethyl alcohol is 15:5:1;
The oxidant is potassium ferrate, and usage amount volume ratio in water is 1:3000-5000;
The high-pressure sodium lamp power of the high-pressure sodium lamp light source illumination-based disinfection is 600-800W, wavelength 260-450nm, main peak Value is 365nm.
2. the method for phthalate pollutant, feature exist in a kind of removal water source gathering ground water body as described in claim 1 In, the bio-resin is the dimerisation products after reacting comprising Isosorbide-5-Nitrae-cyclohexane dicarboxylic acid and linolenic acid with soya bean fatty acid, Softening point is 100-120 DEG C, and the dimerisation products are added in high-speed mixer, stirs 5-10min, is then slowly added The sorbierite for entering 0.05 times of dimerisation products amount starts low speed rotation high-speed cruising and material is adequately stirred inside mixing machine Even, stirring at low speed speed is 180-300r/min, and low speed runing time 10-30min, high-speed stirred speed is 1200-1800r/ Min, high-speed cruising time are 5-15min, and above-mentioned raw material after mixing is put into pelletizer and is kneaded, melted, squeezed Out, pelletizing is after cooling to get arriving the bio-resin.
