【摘要】：目的：本研究旨在通過對崇明縣住宅小區(qū)二次供水情況的調(diào)查,了解崇明縣住宅小區(qū)二次供水水質(zhì)、衛(wèi)生管理及設(shè)施等狀況,探索崇明縣住宅小區(qū)二次供水水質(zhì)的影響因素,并對住宅小區(qū)二次供水與市政管網(wǎng)水的水質(zhì)進(jìn)行檢測和比較,了解二次供水與市政供水管網(wǎng)水水質(zhì)各項指標(biāo)均數(shù)及合格率的差異。 方法：2012年6月-10月,采用方便抽樣對崇明縣60個住宅小區(qū)進(jìn)行問卷調(diào)查和水質(zhì)檢測,了解住宅小區(qū)水質(zhì)、衛(wèi)生管理與設(shè)施等狀況,并建立市政管網(wǎng)水對照。在調(diào)查時對每個調(diào)查小區(qū)物業(yè)單位(無物業(yè)單位則選擇居民)進(jìn)行詢問,同時結(jié)合現(xiàn)場調(diào)查情況填寫調(diào)查問卷,對每個小區(qū)市政管網(wǎng)水和二次供水用戶進(jìn)行入戶采樣,并現(xiàn)場檢測部分水質(zhì)指標(biāo)。用EpiData3.0軟件建立數(shù)據(jù)庫,數(shù)據(jù)的錄入采用雙軌錄入。數(shù)據(jù)庫錄入后使用SPSS13.0進(jìn)行數(shù)據(jù)工作表進(jìn)行清洗(邏輯性檢測、缺漏項回訪等),重新賦值和生成新的變量后,進(jìn)行統(tǒng)計分析并統(tǒng)計分析。 結(jié)果：本次調(diào)查研究60個二次供水住宅小區(qū),采集送檢和現(xiàn)場檢測水樣各60件。預(yù)調(diào)查發(fā)現(xiàn)崇明縣預(yù)調(diào)查顯示崇明縣18個鄉(xiāng)鎮(zhèn)共有設(shè)置二次供水住宅小區(qū)128個,二次供水水箱數(shù)1217只,二次供水蓄水池數(shù)48只。二次供水與市政管網(wǎng)水水質(zhì)指標(biāo)均數(shù)比較,檢測結(jié)果顯示二次供水合格率為75.00%,低于市政管網(wǎng)水合格率的93.33%,具有統(tǒng)計學(xué)意義(P0.05)；實(shí)驗室水質(zhì)檢測結(jié)果顯示：總大腸菌群、菌落總數(shù)、pH、鋁、鋅、總硬度均數(shù)二次供水均高于市政管網(wǎng)水,具有統(tǒng)計學(xué)意義(P0.05)；現(xiàn)場檢測結(jié)果顯示：二氧化氯均數(shù)二次供水低于市政管網(wǎng)水,具有統(tǒng)計學(xué)意義(P0.05)。全縣有總大腸菌群、菌落總數(shù)、渾濁度、臭和味、鐵和二氧化氯6項指標(biāo)不合格；二次供水總大腸菌群與二氧化氯不合格率均為6.67%,市政管網(wǎng)水均符合要求,差異有統(tǒng)計學(xué)意義(P0.05)。二次供水水質(zhì)影響因素分析,不同市政管網(wǎng)水來源等單因素變化時,二次供水合格率不同,差異有統(tǒng)計學(xué)意義(P0.05)。多因素logistic回歸分析,結(jié)果顯示供水來源水廠等級與水箱(蓄水池)定期清洗消毒是二次供水水質(zhì)的影響因素,差異有統(tǒng)計學(xué)意義(P0.05),(OR:0.075,95%CI:0.010-0.571,OR:0.015,95%CI:0.001-0.184)。 結(jié)論：崇明縣住宅小區(qū)二次供水水質(zhì)、衛(wèi)生管理與設(shè)施等現(xiàn)狀與國家有關(guān)法律、法規(guī)和標(biāo)準(zhǔn)要求存在較大差異,住宅小區(qū)二次供水水質(zhì)合格率低于市政網(wǎng)水合格率,不合格主要項目有微生物指標(biāo)、渾濁度及消毒劑余量(二氧化氯)等,主要影響因素主要是供水來源水廠等級與水箱是否定期清洗消毒,這可能增加崇明縣住宅小區(qū)二次供水污染突發(fā)事件發(fā)生風(fēng)險,在下一步的工作中,應(yīng)積極協(xié)調(diào)地方政府各部門共同關(guān)注住宅小區(qū)二次供水問題,清晰各住宅小區(qū)管理的責(zé)任單位,特別是關(guān)注水箱(蓄水池)定期清洗等工作,以防止二次供水污染事件的發(fā)生,保障地方群眾飲水安全。
[Abstract]:Objective: the purpose of this study was to investigate the situation of secondary water supply in residential district of Chongming county and to find out the situation of water quality, sanitation management and facilities of secondary water supply in residential district of Chongming county, and to explore the influencing factors of secondary water supply quality in residential district of Chongming county.The water quality of secondary water supply and municipal pipe network water in residential district is tested and compared, and the difference of water quality index average and qualified rate between secondary water supply and municipal water supply network is understood.Methods: from June to October, 2012, 60 residential quarters in Chongming County were investigated with a questionnaire and water quality test. The water quality, sanitary management and facilities in the residential area were investigated, and the comparison of municipal pipe network water was established.During the investigation, the public property units in each district (no units select residents) were questioned. At the same time, combined with the field investigation, the questionnaire was filled out, and the municipal pipe network water and the secondary water supply users in each district were sampled into the household.Some water quality indexes were tested on the spot.The database is built with EpiData3.0 software, and the data input adopts double track input.After database input, SPSS13.0 is used to clean the data worksheet (logicality check, missing item return visit, etc.). After revaluing and generating new variables, statistical analysis and statistical analysis are carried out.Results: 60 secondary water supply residential areas were investigated and 60 water samples were collected and tested.The preliminary investigation shows that there are 128 residential districts with secondary water supply, 1217 secondary water tanks and 48 secondary water cisterns in 18 townships of Chongming County.Comparing the average of water quality index between secondary water supply and municipal pipe network, the test results show that the qualified rate of secondary water supply is 75.00, which is lower than 93.3333 of municipal pipe network water quality, which has statistical significance (P 0.05), and the results of laboratory water quality test show that: total coliform bacteria,The secondary water supply of total colony pH, aluminum, zinc and total hardness was higher than that of municipal pipe water, which had statistical significance (P0.05), and the results of field test showed that the secondary water supply of chlorine dioxide was lower than that of municipal pipeline water, and had statistical significance (P0.05).The total coliform group, total bacterial count, turbidity, odor and taste, iron and chlorine dioxide were not qualified in the whole county, the unqualified rates of total coliform group and chlorine dioxide in secondary water supply were 6.67 and the municipal pipe water all met the requirements, and the difference was statistically significant (P 0.05).The influencing factors of water quality of secondary water supply were analyzed. The qualified rate of secondary water supply was different when the water source of different municipal pipe network was changed, and the difference was statistically significant (P 0.05).The results of multivariate logistic regression analysis showed that regular cleaning and disinfection of water plants and cisterns (cisterns) were the influencing factors of secondary water quality, and the difference was statistically significant (P 0.05). The difference was statistically significant (P 0.05). There was a significant difference between 95% 95 CI: 0.010-0.571O: 0.015 ~ 95CI0.001-0.1844.Conclusion: the quality of secondary water supply, sanitary management and facilities in residential district of Chongming County are different from the national laws, regulations and standards, and the qualified rate of secondary water supply in residential district is lower than that of municipal water network.The main unqualified items include microbial indexes, turbidity and residual disinfectant (chlorine dioxide), etc. The main influencing factors are whether the water supply source water plant grade and water tank are cleaned and disinfected regularly.This may increase the risk of the sudden incident of secondary water supply pollution in residential areas in Chongming County. In the next step, we should actively coordinate the local government departments to pay common attention to the secondary water supply in residential areas.In order to prevent the pollution of secondary water supply and ensure the safety of drinking water for the local people, it is clear that the responsible units of the management of each residential district, especially paying attention to the regular cleaning of the water tank (cistern), and so on.
