Embodiment 1
[0045] Embodiment 1 Purification of black and odorous water body
[0046] Carry out a 20L severe black and odorous water purification experiment, the background values of the various indicators of the black and odorous water are: NH 3 The -N content is 172.3mg / L, the TP content is 6.0mg / L, the COD content is 618mg / L, the DO content is 0.16mg / L, the redox potential is -249mv, and the transparency is almost 0, which belongs to severe black and odorous water. Severe black and odorous water enters the reaction box from the water inlet pipe through the peristaltic pump, and 10ml of microbial agent is added to the reaction box at a rate of 50ml / L, and 30ml / m 3 Add bio-growth-promoting agent BE, put into two suspension frames whose length, width, and height are 15cm, 4cm, and 10cm respectively, and put an equal volume of elastic three-dimensional filler in the frame, and fix it in the middle of the reaction box, so that it is completely immersed in water . In the plant absorption...
