Embodiment 1
[0072] S1: Pretreat 1L of wastewater, remove oil and filter the wastewater, then add 0.4L of demulsifier to the wastewater, and keep stirring; the demulsifier is an alkyl chain of C 8 h 17 Compound A;
[0073] S2: Distill the wastewater treated in S1, the temperature inside the ammonia distillation tower is 100°C, then adjust the pH of the wastewater to neutral, and add 0.5g of tricobalt tetroxide;
[0074] S3: Pre-oxidize the wastewater under light conditions, filter the wastewater, and then perform super oxidation under light conditions, and add 0.5g of tricobalt tetroxide and 0.25L of 98% hydrogen peroxide solution;
[0075] S4: neutralize the waste water, and then filter it.
[0076] The situation of comparative example 1 and comparative example 4 and the sediment of embodiment 1, and the situation after demulsification are shown in table 1, and it can be seen from table 1 that in embodiment 1.
