Test examples
Comparing the first micro-electrolysis reactor: compared with the reactor disclosed by the invention, the first comparative micro-electrolysis reactor is not provided with a micro-nano mixed water inlet device and a cyclone water separator, and raw water is directly pumped into the bottom of the reactor; and a flushing sludge discharge device is not arranged between adjacent iron-carbon fillers.
Comparing the micro-electrolysis reactor II: compared with the reactor disclosed by the invention, the second comparative micro-electrolysis reactor is not provided with a micro-nano mixed water inlet device and a cyclone water separator, and raw water is directly pumped into the bottom of the reactor.
Comparing the micro-electrolysis reactor III: compared with the reactor of the invention, the third comparative micro-electrolysis reactor is not provided with a micro-nano mixed water inlet device, and raw water is directly pumped into a cyclone water separator at the bottom of the reactor.
The micro-electrolysis reactor of the invention, the first contrast micro-electrolysis reactor, the second contrast micro-electrolysis reactor and the third contrast micro-electrolysis reactor are used for respectively treating raw water, the treated raw water is high-concentration pesticide intermediate wastewater, and the specific water quality parameters and the treatment effect are as follows:
| pH | reaction time/h | COD/mg.L-1 | BOD/mg.L-1 | |
| Raw water | 5-6 | 11000 | 1600 | |
| Contrast micro-electrolysis reactor 1 | 3-4 | 2 | 9050 | 2090 |
| Comparative micro-electrolysis reactor II | 3-4 | 2 | 8770 | 1950 |
