【摘要】：L水廠是內(nèi)蒙古自治區(qū)B市市區(qū)的主要供水廠,供水能力為4.4×104m3/d,目前水廠僅設(shè)置無閥濾池用于去除原水中的鐵、錳,而對砷的去除效果較差。針對L水廠現(xiàn)有工藝狀況及出水水質(zhì)特征,采用投加除砷藥劑后對管式靜態(tài)混合器、跌水曝氣、過濾等工藝進(jìn)行改造。實(shí)際運(yùn)行結(jié)果表明,改造后工藝出水中砷、鐵、錳及濁度數(shù)值分別穩(wěn)定在9μg/L、0.05 mg/L、0.02 mg/L、0.4 NTU以內(nèi),均滿足現(xiàn)行《生活飲用水衛(wèi)生標(biāo)準(zhǔn)》(GB 5749—2006)。此外,工藝改造成本約為15元/m3,運(yùn)行成本增加值0.01元/m3。
[Abstract]:L water plant is the main water supply plant in B city of Inner Mongolia Autonomous region, and its water supply capacity is 4.4 脳 104m3. At present, only valveless filter is set up to remove iron and manganese from raw water, but the removal effect of arsenic is poor. According to the existing process condition and effluent quality characteristics of L water plant, the tubular static mixer, water drop aeration, filtration and other processes were reformed after adding arsenic removal agent. The actual operation results show that the values of arsenic, iron, manganese and turbidity in the effluent of the modified process are stable at 9 渭 g / L and less than 0.05 mg/L,0.02 mg/L,0.4 NTU, respectively. All of them met the current hygienic standard of drinking water (GB 5749 鈮，
