Evaluation of the current status of wastewater management and treatment from super-intensive whiteleg (Penaeus vannamei) shrimp ponds in Ben Tre Province

Tóm tắt

Ben Tre province in Viet Nam must contend with the fact that the farming environment is deteriorating beccause of poor disease management practices, pond wastewater discharge, and bottom muck. The current state of extremely intense shrimp farming in Ben Tre province is depicted in this study. In addition, this study also evaluates the state of Ben Tre province's wastewater treatment and super-intensive shrimp farming practices. Shrimp pond wastewater is often held in settling ponds in super-intensive shrimp farming households in three districts of Binh Dai, Ba Tri, and Thanh Phu of Ben Tre province, however, some households will continue to discharge wastewater through treatment ponds. According to the analysis’s findings, treated shrimp ponds have considerably superior water quality than untreated shrimp ponds. However, the concentration of COD, BOD₅, H₂S, and NH₃ in treated ponds remained higher than the standard of QCVN 02-19:2014/BNNPTNT, although having dropped in comparison to untreated ponds. As a result of the aforementioned fact, it is imperative to conduct research and develop an environmentally friendly and highly effective wastewater treatment process to conserve and circulate water for extremely intensive shrimp ponds in the Ben Tre Province area.
