Embodiment 1
[0081] (1) Arrange groundwater biological reaction wells J1, J2, J3...J6, with a biological reaction radius of 10m;
[0082] (2) After 50 minutes of continuous injection of compressed air into the J1 bioreactor well, the dissolved oxygen in the groundwater of the monitoring well 10m away from the J1 bioreactor well can rise to 5mg / L;
[0083] (3) Use a water pump to pressurize and inject 10L ammonium chloride saturated solution and 1L ammonium phosphate saturated solution into each bioreactor well, and then continue to inject compressed air for 30 minutes to quickly diffuse ammonium chloride and ammonium phosphate to the surrounding areas of the bioreactor well In the groundwater aquifer, the carbon: nitrogen: phosphorus ratio in the groundwater is 100:10:1;
[0084] (4) adopt water pump to pressurize and inject 100kg aerobic biological bacteria into each biological reaction well;
[0085] (5) Use an air compressor to aerate the six groundwater bioreactor wells in turn, and i...
Embodiment 2
[0088] (1) Arrange groundwater biological reaction wells J1, J2, J3...J6, with a biological reaction radius of 8m;
[0089] (2) After 30 minutes of continuous injection of compressed air into the J1 bioreactor well, the dissolved oxygen in the groundwater of the monitoring well 8m away from the J1 bioreactor well can rise to 2mg / L;
[0090] (3) Use a water pump to inject 80L sodium lactate, 5L ammonium chloride and 1L ammonium phosphate saturated solution into each biological reaction well, and then continue to inject compressed nitrogen for 50 minutes to quickly diffuse sodium lactate, ammonium chloride and ammonium phosphate into the biological reaction In the groundwater aquifer around the well, the carbon: nitrogen: phosphorus ratio in the groundwater is 100:10:1;
[0091] (4) Use a water pump to pressurize and inject 150L of anaerobic biological bacteria into each biological reaction well, continuously inject compressed nitrogen for 50 minutes, and quickly diffuse the ana...
