| Abstract |
Swine wastewater is a major source of environmental pollution. Whereas Azolla microphylla (A.microphylla) is a good phytoremediator and source of nutrients for crop and high protein for animals. This study
aimed to identify efficiencies of A. microphylla in swine wastewater (SW) treatment and to investigate the effect of
surface areas and time on the biomass production of A. microphylla and nutrients by using untreated SW. A
completely randomized design (CRD) with three treatments and three replicates was carried out in a polyethylene
house condition at 30.5 ± 3 oC within 21 days from August 6 to 27, 2020. Raw swine wastewater was diluted with
tap water at a ratio (5 :9 5 ) to get swine wastewater 5 % (SW5 ). Nine plastic buckets with three different-surface areas including large (L), medium (M), and small (S) in respective 0.47 m2, 0.22 m2, and 0.16 m2 were selected. Each treatment was inoculated 74 g of the fresh biomass of A. microphylla with total amount volume of SW 60 liters without compensation. The results revealed that biological oxygen demand (BOD) and chemical oxygen demand
(COD) were reduced by 78% and 76%, respectively for 2 weeks. Nitrate nitrogen (NO3
--N) and phosphate (PO43-) were removed 64% and 100% in the medium and large, respectively within 3 weeks. Interestingly, total Kjeldahl nitrogen (TKN), crude protein, and phosphorous (P) were increased in biomass of A. microphylla 2.41%, 15.04%, and 0.43%, while initial values were 1.65%, 10.3%, and 0.37%, respectively. Copper (Cu) and Zinc (Zn) was up
taken 54% and 11% from SW, meanwhile, these were increased in A. microphylla in respective 22%, and 111%.
Hence, A. microphylla not only improved SW but also produced its biomass, a source of protein and nutrients, for sustainable agriculture. |
