Abstract
A combined system for hydroxyl radical removal of antibiotics in pharmaceutical wastewater, involving radical chemistry and water treatment applications. It is equipped with a hydroxyl radical solution generating device, a first liquid-liquid hydrodynamic cavitation miscible device, a second liquid-liquid hydrodynamic cavitation miscible device, a grid pool, a regulating pool, a coagulation pool, a primary sedimentation tank, a secondary sedimentation tank, SBR biochemical reaction tank, 1st to 3rd mechanical pumps, 1st to 4th water flow meters, 1st to 10th solenoid valves and 1st to 5th unit outlet valves. While removing antibiotics in wastewater, it can reduce water body chroma, COD, total organic carbon, etc. After treatment, the chroma of wastewater is less than 30 degrees, BOD 5 <10mg / L, COD<50mg / L, ammonia nitrogen<5mg / L, total organic carbon<15mg / L, and all indicators meet the requirements of the "Pharmaceutical Industry Water Pollutant Discharge Standard". The system has the advantages of good pollutant treatment effect, fast degradation speed, small footprint, and high degree of automation.
Description
[0001] technical background [0002] The invention relates to the application of free radical chemistry and water treatment, in particular to a combined system for removing antibiotics in pharmaceutical wastewater by hydroxyl radicals. Background technique [0003] With the development of the modernization of pharmaceutical technology, my country's pharmaceutical industry has developed rapidly. In terms of antibiotic pharmaceuticals, my country has taken the lead in the world. More than 300 domestic enterprises produce more than 70 varieties of antibiotics, accounting for 20% to 30% of the world's production, and it has become one of the major producers of antibiotic preparations in the world. [0004] With the rapid development, the discharge of pharmaceutical wastewater is becoming more and more prominent. As one of the main types, antibiotic pharmaceutical wastewater is a kind of high-concentration organic wastewater with high chromaticity, refractory biodegradation and ma...
