Abstract: Effects of Pistia statiotes and Rhodospirillum sp.were studied on treating wastewater from rural swine farms in two ponds(area: 398 m2;depth: 3.3 m) in Xinyang of Henan.Pond #1 was treated with Rhodospirillum sp.(50 L×8×108 mL-1),and Pond #2 with Pistia statiotes(100 m-2).After one year of experiment,results show that the combined effect of the two treatments was significant with TP dropped by 41.8%-76.0%,TN by 61.8%-81.0%,COD by 66.8%-79.1% and BOD5 by 64.8%-82.3%.It demonstrates that Pistia statiotes and Rhodospirillum sp.can greatly improve wastewater quality of swine farm.

Key words: Rhodospirillum sp., Pistia statiotes, wastewater of swine farm
