【摘要】：重視飲水系統(tǒng)衛(wèi)生質(zhì)量安全是預(yù)防雞群發(fā)病的一個(gè)重要環(huán)節(jié)。規(guī)�；u場飲水管道全封閉、內(nèi)部清潔困難,而為提高飼料轉(zhuǎn)化率和抗應(yīng)激能力,普遍通過飲水系統(tǒng)添加多維等產(chǎn)品,加速了飲水系統(tǒng)污染、細(xì)菌超標(biāo)等。目前雞場飲水系統(tǒng)常用的反向沖洗水線、清潔劑洗滌清潔方式,存在殺菌不徹底、影響蛋雞腸道微生物和廢水過度排放等嚴(yán)重問題。該文研究了添加多維溶液對(duì)水線內(nèi)水質(zhì)影響變化規(guī)律,并對(duì)比研究了添加多維溶液后,沖洗水線、添加微酸性電解水2種方式對(duì)雞場飲水系統(tǒng)的殺菌規(guī)律。結(jié)果表明:飲水系統(tǒng)中添加多維溶液2、4、6、12、24、36、48、72 h后,水線內(nèi)細(xì)菌濃度總數(shù)的對(duì)數(shù)值分別增加9.96%、5.33%、6.04%、7.47%、4.98%、5.69%、4.27%、4.98%;沖洗水線能沖洗掉飲水管壁附著沉積層,一定程度上減少飲水中細(xì)菌總數(shù),但飲水中細(xì)菌濃度總數(shù)仍高于中國飲水衛(wèi)生質(zhì)量標(biāo)準(zhǔn);添加余氯0.3 mg/L的微酸性電解水24 h后,飲水管線中細(xì)菌濃度降低34.7%,48 h后水線中細(xì)菌濃度的對(duì)數(shù)值維持為(1.83±0.05 lg(CFU/m L)),添加余氯0.3 mg/L微酸性電解水使水線內(nèi)細(xì)菌濃度總數(shù)顯著降低(P0.01),達(dá)到中國飲水衛(wèi)生標(biāo)準(zhǔn),且規(guī)模化雞場飲水系統(tǒng)添加微酸性電解水作為殺菌消毒劑可減少廢水產(chǎn)生排放。該研究結(jié)果為雞場飲水系統(tǒng)選擇長期添加使用的消毒劑提供了參考依據(jù)。
[Abstract]:The importance of sanitary quality and safety of drinking water system is an important link to prevent chicken flocks. In order to improve the feed conversion rate and anti-stress ability, the drinking water pipeline of large-scale chicken farm is completely closed and the internal cleaning is difficult. In general, multi-dimensional products are added to the drinking water system, which accelerates the contamination of the drinking water system, the bacteria exceeding the standard, and so on. At present, the common reverse washing lines and detergent cleaning methods used in the drinking water system of chicken farms are not completely germicidal. The effects of adding multi-dimensional solution on the water quality in the water line were studied, and the effects of adding multi-dimensional solution on the water quality of the water line were compared, and the flushing water line was studied after adding the multi-dimensional solution, and the effect of adding multi-dimensional solution on the water quality was studied. The germicidal regularity of drinking water system in chicken farm was studied by adding micro-acid electrolytic water. The logarithmic values of the total bacterial concentration in the water line increased 9.96 / 5.336.04 / 7.47, respectively, and 4.98 / 5.69 / 4.274.98.The washing line could wash the sediment layer attached to the drinking water pipe wall and reduce the total bacteria in drinking water to a certain extent, but the total bacterial concentration in drinking water was still higher than that of China's drinking water sanitation quality standard. After the addition of residual chlorine 0.3 mg/L, the electrolytic water was slightly acidic for 24 h. The logarithmic value of bacterial concentration in drinking water pipeline was maintained at 1.83 鹵0.05 lg(CFU/m / L after 48h decrease. Adding residual chlorine 0.3 mg/L micro-acid electrolytic water, the total bacterial concentration in the water line decreased significantly (P 0.01), which reached the hygienic standard of drinking water in China. Adding micro-acid electrolytic water as a germicidal disinfectant can reduce the discharge of wastewater in the large-scale drinking water system of chicken farm. The results provide a reference basis for the selection of disinfectants used for a long time in the drinking water system of chicken farm.
