1. the application of pilea cadierei in processing livestock breeding wastewater, it is characterized in that:

  • water distributor is established in the bottom at rubber drum, in bucket, to be covered with thickness be 5cm, the diameter gravel bed at 2-5cm to bottom, is covered with the coarse sands layer that 10cm is thick on gravel bed, above layer of sand, is the pedosphere that 10cm is thick;

    Under natural condition, by the pilea cadierei seedling collected, directly be transplanted in rubber drum, with tap water, stablize 15 days, regular quantitative pouring livestock breeding wastewater after plant to be planted is stable, gather the water quality data of ammonia nitrogen, total phosphorus, total nitrogen, chemical oxygen demand, total content of organic carbon in water sample and mensuration water sample, the average purification rate obtained respectively ammonia nitrogen, total phosphorus, total nitrogen, chemical oxygen demand, total organic carbon is 90.01%, 89.93%, 95.71%, 91.22%, 96.42%;

    According to average purification rate data, further the pilea cadierei of some amount is planted in the Wetland Environment of livestock breeding wastewater, the over-ground part of the pilea cadierei of regularly cutting back pruning plantation, by regular pruning, prevent that deadwood and rotten leaf from falling in water, prevent the secondary pollution to water body, after pilea cadierei is bred certain biomass, just can effectively purify the livestock breeding wastewater in wetland, the amount of plantation pilea cadierei is 6 strains/bucket.
