Device for recycling domestic waste water

Abstract

The invention relates to a device for recycling domestic waste water. The structure of the device comprises a water storage tank and a waste water collecting and treating device, wherein the water storage tank is arranged in a bathroom of a lower floor; the waste water collecting and treating device can collect waste water of a high rise building; the lower part of the waste water collecting and treating device is provided with a water inlet pipe communicated with the water storage tank; the upper part of the water storage tank is provided with a high water level float switch, while the lower part is provided with a low water level float switch capable of replenishing tap water; and the lower part of the storage tank is communicated with a toilet pipe and provided with a tap water replenishing control switch. Due to the adoption of the structure, domestic waste water produced by a resident of an upper floor or domestic waste water drained into a main sewer by other residents of the high rise building is filtered simply and used for flushing a toilet, so that the domestic waste water is utilized fully, over 50 percent of domestic water can be saved effectively and sustainable utilization of water resources is realized. The device is suitable to be arranged in the existing buildings and is also suitable to be uniformly arranged in newly-built buildings during construction and a detachable structure of the device can also meet the requirements of residents and be used selectively.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a domestic wastewater recycling device. Background technique [0002] Water is one of the important resources for the survival and development of human beings. It is an indispensable and irreplaceable special resource. However, due to irrational use, the originally scarce fresh water resources are becoming increasingly tense. Rational use of water resources is an urgent task for the sustainable development of human beings, and water conservation is the key to the rational use of water resources, and it is one of the fastest, most feasible, most extensive and effective ways to maintain the sustainable use of water resources. [0003] People will produce a lot of relatively clean wastewater in their daily life, such as bathing, washing clothes, washing hands, face washing, washing vegetables, washing rice, etc. The domestic wastewater generated is directly discharged through the sewe...

Problems solved by technology

In response to this problem, some people use buckets and other containers to store these available domestic wastewater to flush toilets, and some use water pumps to pump domestic wastewater into special storage tanks for flushing toilets, but the former uses manual storage of wastewater. The method in the container is cumbersome, and the latter method increases the cost of electric energy and is difficult to popularize and apply

Simultaneously, how low-rise resident utilizes the domestic waste water of high-rise resident, there is no effective way in the prior art
