摘要：

目的：检测苍山花甸坝龙潭、西坡、农场总部3个饮用水源中的细菌总数和大肠菌群。方法：采用平板菌落计数法和多
管发酵法分别对水样中的细菌总数和大肠菌群进行检测。结果：龙潭水源中未检到细菌和大肠菌群，而农场总部水源和西坡水源中检出大量细菌和大肠菌群，其中西坡水源中细菌总数>300/mL，大肠菌群数>230/L；农场总部水源细菌总数=189/mL，大肠菌群数=230/L。结论：苍山花甸坝农场总部水源和西坡水源中的细菌总数和大肠菌群均不符合我国生活饮用水卫生标准（GB5749-2006），不适于直接饮用，而龙潭水源则符合该标准。

Abstract:

Objective: To detect the total count of bacteria and coliform bacteria of the three drinking water resources of Longtan, Xipo and Farm headquarters of Cangshan Huadianba. Methods: Using the methods of plate culture count and multiple-tube fermentation technique to detect the total count of bacteria and coliform bacteria in the three drinking water sources respectively. Results: The bacteria and coliform bacteria were not detected in the water resource of Longtan, but a large number of bacteria and coliform bacteria were detected in the drinking water resources of Xipo and Farm headquarters. The total count of bacteria and coliform bacteria was more than 300/mL and 230/L respectively in the drinking water resources of Xipo. It was 189/mL and 230/L respectively in the drinking water resources of the Farm headquarters. Conclusion: The water drinking resource in Longtan meets the requirements of current national standards for drink water (GB5749-2006), while two other drinking resources do not meet this standard.

Key words: Cangshan Huadianba, drinking water resource, total count of bacteria, coliform bacteria
