| Influent concentration | 6-9 | ≤260 | ≤105 | ≤95 | ≤40 | ≤3 |
| Go out water concentration | 6-9 | ≤30 | ≤18 | ≤12 | ≤8 | ≤0.5 |
Table 6 Inlet and outlet water water quality situation unit: mg/L.
BAF: BAF is divided into biological respinse filtering layer and supporting layer, and the cobble that tiles in supporting layer, filtering layer are sexangle polypropylene honeycomb filler; Flooding quantity is 1000m
3/ d; Water outlet after sewage work handles is because ammonia nitrogen and total phosphorous exceed standard (not reaching one-level B emission standard in " urban wastewater treatment firm pollutant emission standard GB 18918-2002 "), and water quality is shown in Table 7.
In the present embodiment, solution is: the filtering layer of this sewage work's BAF is replaced to the filler bag.Filler packs the mode of work with embodiment 1, and cloth (manufacturer is with embodiment 1) raw material is a trevira 35%, polypropylene fibre 55%, cotton fibre 10%; Bag shape biologic packing material is of a size of 1000mm * 1000mm; Filling substrate is quartz sand and vegetable mould (volume ratio is 3: 1), and stacking factor is 80%; Make the sealing of bag shape biologic packing material and sack with embodiment 1.
In filtering layer, place the filler bag, the preferred arrangement of filler bag as shown in figure 15: with closely knit the piling up of filler bag multilayer, height is 2.5m; The quantity of filler bag is 600 bags; Do not establish stationary installation and mounting block.
Reach one-level B emission standard in " urban wastewater treatment firm pollutant emission standard GB18918-2002 " after the sewage disposal, as shown in table 7.The result shows that the biologic packing material bag in the present embodiment is applicable to this BAF, and the ability of disposing of sewage increases with respect to sexangle polypropylene honeycomb filler.
The advantage of present embodiment is that the microbial film that sewage and filler are wrapped fully contacts, by the biological metabolism effect, and the physical filtering effect, the purification of sewage is finished in the adsorptions of filler bag etc.
