Abstract:

In this study, a novel water treatment system suitable for rice planting was designed and constructed to treat and recycle wastewater from aquaculture ponds. According to the performance results of the system, the water purification efficiency was optimal when the hydraulic load was 0.29-0.58 m/d and the gas water ratio was 2-4. The removal rates of TAN, TN, TP and CODMn from wastewater were 33.75%-34.31%, 59.21%-64.53%, 68.43%- 73.75% and 71.66%-74.37% respectively when the hydraulic load was 0.58 m/d and the gas water ratio was 2. Meanwhile, rice yield reached 7127.01 kg/hm2. Therefore, this water treatment system which can efficiently reuse nutrients from wastewater and purify water is a new technology for the treatment of aquaculture wastewater in agriculture-aquaculture system in China.
