节能一体化单片机家庭循环用水系统的设计

摘要再生水的利用可以减少人类对自然水资源的依赖和破坏，缓解水资源紧张的现状。如果每个家庭能实现污水再利用，不但减少家庭用水的开销，而且减少了国家在污水处理方面的投资，大幅提高我国污水再生利用率。家庭污水再生利用也有助于改善生态环境，实现水的良性循环利用。本设计中可按照功能分为控制环节、废水过滤环节、过滤水储存环节三部分，废水过滤环节能够将生活污水进行处理的到水质不高的可利用二次用水；过滤水储存环节可以将过滤后的水进行储存以实现生活用水的节约使用；控制环节可以控制回路中的电磁阀将储存的水导向所需用水的地方。主要研究基于单片机控制的家庭循环用水系统。该系统能够自动的将洗衣服、淘米、洗菜等用水进行过滤并收集在水箱中，以便于冲厕所和拖地等对水质要求不高的二次用水，以达到节水目的。关键词：单片机；智能节水；循环利用AbstractThe use of recycled water can reduce the dependence and destruction of human beings on natural water resources and alleviate the current situation of water resources shortage.

再生水的利用可以减少人类对自然水资源的依赖和破坏，缓解水资源紧张的现状。如果每个家庭能实现污水再利用，不但减少家庭用水的开销，而且减少了国家在污水处理方面的投资，大幅提高我国污水再生利用率。家庭污水再生利用也有助于改善生态环境，实现水的良性循环利用。

本设计中可按照功能分为控制环节、废水过滤环节、过滤水储存环节三部分，废水过滤环节能够将生活污水进行处理的到水质不高的可利用二次用水；过滤水储存环节可以将过滤后的水进行储存以实现生活用水的节约使用；控制环节可以控制回路中的电磁阀将储存的水导向所需用水的地方。

主要研究基于单片机控制的家庭循环用水系统。该系统能够自动的将洗衣服、淘米、洗菜等用水进行过滤并收集在水箱中，以便于冲厕所和拖地等对水质要求不高的二次用水，以达到节水目的。

This system can filter and collect the water for washing, rice and vegetables in the water tank, so as to make it easy to flush the toilet and mop the floor and other secondary water which does not require high water quality, such as washing the toilet and dragging the ground and so on, and the system can automatically filter and collect the water used for washing, rice and vegetables in the water tank. In order to achieve the purpose of saving water.
