Test example 1
And (3) screening the pyrolysis temperature: fixing biological filler components (0.5 kg sweet potato vine, 0.5g sweet potato residue, 0.5kg wormwood, 0.5kg compound fertilizer, 0.5kg ceramsite and 0.2kg expanded vermiculite), and screening the pyrolysis temperature. The pig manure sewage is evenly mixed and evenly divided into 5 groups, and screening is carried out according to indexes of biochemical oxygen demand (BOD 5), chemical oxygen demand (CODcr) (mg/L), suspended matters (SS) (mg/L) and ammonia nitrogen (NH 3-N) (mg/L). The results are as follows:
From the results, as the pyrolysis temperature increased, each index value before the comparative treatment was decreased, but at the pyrolysis temperature of 180 ℃, each index value was relatively the lowest, so that the process pyrolysis temperature of 180 ℃ was determined.
Test example 2
screening the sweet potato vine, the sweet potato residue and the wormwood in proportion: fixing compound fertilizer, ceramsite and expanded vermiculite, and screening sweet potato vine, sweet potato residue and wormwood in proportion. The pig manure sewage is uniformly mixed and averagely divided into 9 groups:
1 group of sweet potato vine, sweet potato residue and wormwood in a ratio of 0:1
2 groups of sweet potato vine, sweet potato residue and wormwood in a ratio of 1:0:1
3 groups of sweet potato vine, sweet potato residue and wormwood are proportioned at the ratio of 1:1:0
4 groups of sweet potato vine, sweet potato residue and wormwood are mixed according to the proportion of 4:5:3
5 groups of sweet potato vine, sweet potato residue and wormwood are mixed according to the proportion of 4:7:3
6 groups of sweet potato vine, sweet potato residue and wormwood are proportioned at a ratio of 5:5:3
7 groups of sweet potato vine, sweet potato residue and wormwood are proportioned at a ratio of 5:7:3
8 groups of sweet potato vine, sweet potato residue and wormwood are mixed according to the proportion of 4:3:7
9 groups of sweet potato vine, sweet potato residue and wormwood are proportioned at a ratio of 5:3:7
screening is carried out by indexes of biochemical oxygen demand (BOD 5), chemical oxygen demand (CODcr) (mg/L), suspended matter (SS) (mg/L) and ammonia nitrogen (NH 3-N) (mg/L) of the pig manure sewage. The results are as follows:
The results show that the index values of each group are reduced before the comparison treatment, and the index values of each group are reduced to a large extent compared with the index values of 1-3 groups and 4-9 groups, which indicates that the sweet potato vine, the sweet potato residue and the wormwood have a synergistic effect and are all absent. Meanwhile, when the ratio of the sweet potato vine to the sweet potato residue to the wormwood is 4:7:3, the index value is the lowest, so that the ratio of the sweet potato vine to the sweet potato residue to the wormwood is 4:7: 3.
