Embodiment 1
[0050] S1, configure BPA simulated wastewater 12mg / l, collect domestic sewage COD Cr 351mg / L, BOD 5 167mg / L, ammonia nitrogen 26mg / L, total phosphorus 2.2mg / L;
[0051] S2. Adjust the flow rate of BPA simulated wastewater to 5L / h, adjust the initial pH of simulated BPA wastewater to 4.5, and add 1.2g / L of α-Fe 2 o 3 The amount of photocatalyst, the amount of peroxysulfate added is 0.4g / L, the aeration rate is controlled to be 0.6L / min, and the concentration of BPA in the effluent is 1.05mg / L by high-performance liquid chromatography and the national standard method;
[0052] S3. SRPCR treats the effluent, adjusts the domestic sewage flow rate to 5L / h, and merges it into PCRIT. The operating cycle is 24 hours, and the single pool working cycle is 12 hours. The wet-dry ratio is controlled to be 1:1, that is, 1 hour is used for water distribution and 3 hours for Drainage, 4h is used for drying, using high-performance liquid chromatography and national standard method detection...
