The present invention is based on the different quality requirements or different quality requirements of the water supply and discharge water of different water use facilities, wherein the water supply quality requirements of the primary water use facilities are higher than the water supply quality requirements of the secondary water use facilities, and the quality of the discharge water is relatively low. It can be used as a secondary water facility after being treated by the water collection tank (the water collection tank can be treated in different ways according to the actual situation, such as simple water collection, sedimentation and/or filtration, or even biological treatment, etc.) Water supply, so just provides possibility for the implementation of the present invention, and this situation also really exists in domestic water use in reality. Moreover, further classification is also feasible. One of the classification methods is to refine the classification of primary water use and secondary water use. The discharge water from the facilities is used for the secondary water facilities, the discharge water from the secondary water facilities is used for the tertiary water facilities, etc., and so on.

The further improved scheme provided by the present invention is suitable for refining the classification of primary water and secondary water (corresponding to the technical scheme of setting up two water sources respectively as a first-class primary water facility and a second-class primary water collection tank). That is, according to the nature of the primary water, it can be divided into two categories. The impurities contained in the discharged water of one type of primary water can be basically removed after treatment in the water collection tank (such as filtration and sedimentation, etc.), and the pollution of the treated water is relatively low. It can be used for growing flowers, roughly washing items, cleaning and other occasions (this type of water is Class I secondary water), and the discharge water of Class II primary water after the above filtration and precipitation is relatively high in pollution, so it is not suitable for growing flowers and Cleaning, etc., but can be used for flushing toilets, washing mops, etc. (this type of water is second-class secondary water). In practice, the primary water facilities can be classified according to the general situation of the discharge water of the primary water facilities according to the appropriate standard, and the secondary water facilities can be classified according to the demand status of the secondary water facilities. The quality of the water tank after treatment is better than that of the second-class primary water facilities after being treated by the water collection tank. The discharge water from the facilities can be used for Class I secondary water facilities and Class II secondary water facilities after being treated by the water collection tank, and the discharge water from the Class II primary water facilities can only be used for Class II secondary water facilities after being treated by the water collection tank. . In order to avoid the equipment of the present invention being too complicated, usually the washing pool in the kitchen can be simply listed as a first-class primary water facility, and the washing machine etc. installed in the bathroom are listed as a second-class primary water facility. It can be classified as a first-class primary water facility, but in order to reduce the setting of water pipelines, it can also be regarded as a second-class primary water facility, and the second-class water facility is usually a toilet tank and a pool for flushing mops. In terms of pipeline settings, multiple faucets can be set up to be used as Class I secondary water facilities and Class II secondary water facilities to provide corresponding water.

If water facilities can be divided into three or more times as required, as long as the structure of the present invention is simply repeated many times, multiple utilization of water can be realized.

When describing the dimensions in this manual, the thickness of the plates constituting the box, etc. is ignored. When the material thickness of the box and other structures cannot be ignored, the material thickness should be discarded in the corresponding dimensions.
