Some physico-chemical parameters of Kaljani River were studied in and around Alipurduar municipality. The principal characteristics of Kaljani River are high TSS, Mg-hardness, COD, and Phosphate 'P' Comparison of water quality parameters of the two rivers demonstrated higher range of alkalinity, ammonia 'N' content and chloride content in Torsa than Kaljani. River Kaljani showed higher COD range than Torsa. Mean BOD value of both these rivers ranged between 0.93-1.65 mg/l. Overall TDS content of Kaljani was found to be lower than Torsa. Maximum phosphate 'P' content was observed at the downstream of both the rivers.
对阿利普尔杜尔市及其周边的卡尔贾尼河的一些理化参数进行了研究。卡尔贾尼河的主要特征是总悬浮固体(TSS)、镁硬度、化学需氧量(COD)和磷酸盐“P”含量较高。两条河流的水质参数比较表明,托尔萨河的碱度、氨“N”含量和氯化物含量范围高于卡尔贾尼河。卡尔贾尼河的化学需氧量范围高于托尔萨河。这两条河流的平均生化需氧量(BOD)值在0.93 - 1.65毫克/升之间。发现卡尔贾尼河的总溶解固体(TDS)含量低于托尔萨河。在两条河流的下游均观测到最大磷酸盐“P”含量。
