在新时代背景下，农村自来水一体化水处理设备的发展与实践成为了提升农村居民生活质量、保障饮用水安全的关键技术。随着科技的进步，一体化设备不仅能够有效去除含有病原菌和其他污染物的自来水中的杂质，还能提供稳定可靠的清洁饮用水。

首先，让我们从一个名叫“青山镇”的典型案例开始。该镇位于山区，地处偏远，其传统自来水处理方式存在明显不足：手工过滤效率低、维护成本高且难以保证每天都能得到清洁的饮用水。这导致了居民普遍面临生病和健康问题。

然而，在2018年，当地政府决定投资购买一批农村自来水一体化处理设备，并对现有的供水系统进行升级改造。一旦安装完成，这些设备就可以自动检测并去除所有可能引起疾病的细菌和化学物质，从而为当地居民提供了纯净透明的自来水。

根据统计数据，青山镇人口中患上胃肠道疾病的人数大幅度降低，而整体健康状况也有了显著提升。此外，由于采用了一体化设计，这些设备需要较少的人力维护，使得成本降低，同时也节省了大量人力资源用于其他工作之上。

此外，我们还可以举例说明河北省的一个名为“小庄乡”。在那里， villagers faced a severe water crisis due to the contamination of their local well. The villagers suffered from frequent illnesses, and many children were forced to stay at home because of diarrhea and other waterborne diseases.

The government took immediate action by installing a comprehensive water treatment system that included UV disinfection, sedimentation, filtration, and reverse osmosis. This one-stop solution ensured that the treated water was free from bacteria, viruses, parasites and other contaminants.

The results were astounding - the number of cases related to gastrointestinal infections plummeted dramatically. Moreover, with clean drinking water available round-the-clock, people's quality of life improved significantly. Children could now attend school regularly without worrying about getting sick.

In conclusion, the development and application of agricultural self-sufficiency integrated water processing devices has been instrumental in ensuring access to safe drinking water for rural residents across China. These systems are not only effective in removing impurities but also contribute to better health outcomes and increased productivity among rural communities.

As we look forward into this new era where technology continues to evolve rapidly; it is imperative that we continue investing in innovative solutions such as these integrated devices so that no person should ever have their basic human right – access to clean drinking-water – compromised due solely on account of their geographical location or socio-economic status
