In this study, the potential reuse of kitchen wastewater (KWW) in irrigation was analyzed to reduce the present freshwater demand. To know the suitability of KWW for irrigation, the samples were first collected from an educational institute in India and then characterized according to its physical, chemical, and bacteriological properties. The characterized data were then compared with the standard limit for irrigation Food and Agriculture Organization (FAO in Water quality for agriculture. Irrigation and drainage paper 29, M56, 1994) and the US Salinity Laboratory (USSL). Apart from the above irrigation standards, the characterized data were also compared with sodium adsorption ratio (SAR), residual sodium carbonate, sodium percentage (Na%), magnesium hazard (MH), Kelly’s ratio (KR), and permeability index to get better clarity. From the characterization, it was found that carbonate, fluoride, chromium, and Escherichia coli were absent, whereas parameters like pH, chloride, iron, copper, magnesium, lead, nickel, sodium, calcium, zinc, aluminum, and sodium adsorption ratio were within the permissible limit. The result obtained from the USSL classification system suggested that 30.77% of KWW samples are safe for irrigation. Moreover, its quality was found to be safe for irrigation based on SAR, Na%, KR, and MH. For better decision making of KWW reuse in irrigation, the output of Mamdani fuzzy inference system (MFIS) was compared with the USSL classification system. The overall agreement between USSL and MFIS was found to be 55.6% for KWW.

在这项研究中，分析了厨房废水在灌溉中的潜在再利用，以减少当前的淡水需求。为了了解KWW是否适合灌溉，首先从印度的一家教育机构收集了样本，然后根据其物理，化学和细菌学特性对其进行了表征。然后将特征数据与灌溉食品和农业组织的标准限值（FAO，农业用水质量。灌溉和排水论文29，M56，1994）和美国盐度实验室（USSL）进行比较。除了上述灌溉标准外，还将特征数据与钠吸附率（SAR），残留碳酸钠，钠百分比（Na％），镁危害（MH），凯利比（KR）和渗透系数进行比较，以获得更好的结果。明晰。不存在大肠杆菌，而pH，氯化物，铁，铜，镁，铅，镍，钠，钙，锌，铝和钠的吸附率等参数均在允许的范围内。从USSL分类系统获得的结果表明，30.77％的KWW样品可以安全灌溉。此外，基于SAR，Na％，KR和MH，发现其质量对于灌溉是安全的。为了更好地决策KWW在灌溉中的再利用，将Mamdani模糊推理系统（MFIS）的输出与USSL分类系统进行了比较，发现USSL与MFIS在KWW上的总体协议为55.6％。
