摘要
豆腐行业在生产过程中,每生产1公斤大豆原料要使用±25升水。作为豆腐原料的大豆含有蛋白质、碳水化合物、脂肪等营养成分,因此产生的废液中有机物含量高,具有污染环境的潜力,其生物需氧量(BOD)为467 mg/L,化学需氧量(COD)为668.2 mg/L。控制水污染的努力可以通过使用活性污泥系统处理生物技术来克服。本研究旨在分析受污染水体沉积物作为活性污泥的主要成分对降低生物需氧量(BOD)和化学需氧量(COD)水平的有效性,并确定驯化过程中微生物的生长速度。在好氧条件下,采用曝气器和泵作为搅拌器,对4种不同的组分分批进行了研究。结果表明,处理IV的污泥组成,即由(60%废弃物、40%营养物和培养RPH污泥)组成的污泥组成,在曝气60 h时为最佳组成,去除BOD浓度为90.10%,COD浓度为COD。生物量比增长率为0.054 d -1, COD还原值分别为46.21 mg/L和84.14 mg/L,达到87.41%。
Penerapan Metode Activated Sludge dalam Pengolahan Limbah Cair Industri Tahu Beru
The tofu industry in its production process uses ± 25 liters of water per 1 kg of soybean raw material. Soybean used as raw material for tofu contains protein, carbohydrates, fat, and other nutritional ingredients so that the resulting liquid waste contains high organic matter that has the potential to pollute the environment with a value of Biological Oxygen Demand (BOD) of 467 mg/L and Chemical Oxygen Demand (COD) of 668.2 mg/L. Efforts to control water pollution can be overcome by processing biotechnology using an activated sludge system. This study aims to analyze the effectiveness of polluted water sediment as the main ingredient of activated sludge in reducing levels of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) and to determine the growth rate of microorganisms in the acclimatization process. This research was carried out on 4 different composition variations in batches under aerobic conditions using an aerator and a pump as a stirrer. The results showed that the composition of the sludge in treatment IV, namely the composition of the sludge consisting of (60% Waste, 40% Nutrients, and cultured RPH sludge) was the best composition at 60 hours of aeration with the effectiveness of removing BOD concentration of 90.10% and COD concentration. amounted to 87.41% or achieved a reduction value of 46.21 mg/L of BOD concentration and 84.14 mg/L of COD concentration with a specific biomass growth rate of 0.054 day-1.
