摘要

水产养殖产生的废物最终会影响水质和养殖物种的生长性能。因此,研究人员调查了利用水产养殖废物中的光合细菌(PSB)处理鱼类养殖废水的潜力。本研究从鱼塘收集废水,在阳光照射的无菌瓶中培养 14 天。在水质添加剂实验中,准备了五种处理(在 30 cm3 的水族箱中),即养殖 PSB(T1)、水生植物大黄(T2)、水生植物沙参(T3)、阳性对照(P)和阴性对照(N)。每种处理各放入 5 个蓑衣草个体(体长 2.5±0.5 厘米),饲养 30 天。同时,在废水处理方面,准备了四个处理(在 30 cm3 的水族箱中),分别为孵化鱼池废水(S1)、孵化鱼缸废水(S2)、阳性对照(P)和阴性对照(N)。结果表明,与其他处理相比,T1 处理能明显改善和保持水质。结果表明,在 S1 和 S2 中添加 T1 30 天后,氨氮和亚硝酸盐的含量从第 1 天开始逐渐下降,直至第 18 天。而从废水实验的第 21 天到第 30 天,氨氮和硝酸盐的含量为零。使用 PSB 处理显示了细菌利用和吸收营养物质的能力,从而保持和改善了水质。有益细菌在培养系统中的潜在用途可以加速氮循环,从而实现可持续的废水管理。

Photosynthetic Bacteria as an Alternative Wastewater Treatment in Freshwater Aquarium Fish Set Up
Waste produced from aquaculture ultimately hampered the water quality and growth performance of species cultured. Therefore, the potential exploitation of photosynthetic bacteria (PSB) from aquaculture waste was investigated to treat the wastewater in the fish culture. In this study, the wastewater was collected from a fishpond and cultured in sunlight-exposed sterile bottles for 14 days. In the water additive experiment, five treatments (in a 30 cm3 aquarium) were prepared namely cultured PSB (T1), aquatic plant hornwort (T2), aquatic plant salvinia (T3), positive control (P), and negative control (N). Five individuals of Hyphessobrycon herbertaxelrodi (2.5±0.5 cm length) were placed in each treatment and reared for 30 days. Meanwhile, for the wastewater treatment, four treatments (in a 30 cm3 aquarium) were prepared namely wastewater from the hatchery fishpond (S1), wastewater from the hatchery fish tank (S2), positive control (P), and negative control (N). The results obtained indicate that T1 treatment significantly improved and maintained the water quality as compared to other treatments. The results showed the amount of ammonia and nitrite in S1 and S2 supplied with T1 for 30 days gradually decreased from day 1 until day 18. While zero amount of ammonia and nitrate was acquired from day 21 until day 30 of the wastewater experiment. The treatment with PSB showcased the bacteria's ability to utilize and absorb nutrients, thereby maintaining and improving water quality. The potential use of beneficial bacteria in the culture system can accelerate the nitrogen cycle for a sustainable way of wastewater management.
