Abstract

The dairy industry is the fastest growing industry in the world. Discharged water is more easily contaminated with high levels of organic substances, pollutants and microbes. Consuming raw milk effluents can cause disease transmission to living beings and can be harmful to the environment. The present investigation was carried out for the characterization and its biodegradation process of dairy effluents using locally selected isolated fungi. For the biodegradation process, three species of fungi such as ASP, ALT, FUS were isolated and identified from dairy wastewater using the CFU method. During the monsoon, the dairy farm (CMP) collected the seasonal milk effluent. Aeration followed by filtration for degradation was performed. During the research some physicochemical parameters such as pH, BOD, COD, TDS, TSS, TKN, etc., were analyzed. Effluents from milk processing and ASP fungal isolate have been found to have a high capacity to break down organic matter. The BOD5 and COD value of the crude effluent improved by 87.75 and 81.02%, respectively, after 5 days. Biodegradation with fungal isolates can be a perfect method for treating dairy wastewater. This treatment technique can be used for industrial purposes, starting from selected fungal isolates, Aspergillus was more vital than Alternaria and Fusarium species for the biodegradation of organic content in dairy effluents. After studying all the aspects considered, aeration followed by filtration was extremely effective in reaching the most notable level of contamination present in wastewater. The possible reason could be related to the high adsorption capacity of activated carbon and assimilation by sawdust. Activated coal and sawdust can remove an assortment of organic matter from contaminated water. At long last, biodegradation of dairy wastewater by chosen fungal isolates is viable treatment technology, particularly on account of using locally isolated fungal strains.

综合废水处理系统中内源真菌分离物对乳制品废水的生物降解

摘要

乳制品行业是世界上增长最快的行业。排放的水更容易被高水平的有机物质、污染物和微生物污染。饮用生奶流出物会导致疾病传播给生物，并对环境造成危害。本研究是针对使用当地选择的分离真菌对乳制品流出物进行表征及其生物降解过程进行的。对于生物降解过程，使用 CFU 方法从乳品废水中分离鉴定了 ASP、ALT、FUS 三种真菌。在季风期间，奶牛场 (CMP) 收集了季节性牛奶流出物。进行曝气，然后进行过滤以进行降解。在研究过程中，对pH、BOD、COD、TDS、TSS、TKN等一些理化参数进行了分析。已发现来自牛奶加工和 ASP 真菌分离物的废水具有很高的分解有机物的能力。5天后，粗出水BOD5和COD值分别提高了87.75%和81.02%。用真菌分离物进行生物降解是处理乳品废水的完美方法。这种处理技术可用于工业目的，从选定的真菌分离物开始，对于乳制品废水中有机物的生物降解，曲霉比链格孢属和镰刀菌更重要。在研究了所有考虑的方面后，曝气和过滤在达到废水中最显着的污染水平方面非常有效。可能的原因可能与活性炭的高吸附能力和锯末同化有关。活性煤和锯末可以从受污染的水中去除各种有机物。最后，通过选择的真菌分离物对乳品废水进行生物降解是可行的处理技术，特别是考虑到使用局部分离的真菌菌株。
