The floor plan of the apartment and the washroom is shown in Figure 1. There is one downspout in the washroom and one in the toilet, and the toilet is the main downspout. A large amount of waste water produced by washing and washing clothes in the washroom flows into the main downpipe of the bathroom through the auxiliary downpipe of the washroom and is discharged into the sewer. This method causes a direct waste of a large amount of sewage with reuse value.
目前也有对公寓废水再利用的系统，但是这些系统都需要在每一层的洗漱间单独设立1至2个水箱，用于收集各公寓楼层洗漱间产生的污水，每一个水箱引出1至2个水管与下层的冲便水箱相连，水箱中的污水臭味较大，除臭工作量大，占地面积大，整体工程量大，难以大范围推广实施。At present, there are also systems for reusing apartment wastewater, but these systems require 1 to 2 water tanks to be installed separately in the washrooms of each floor to collect the sewage generated in the washrooms of each apartment floor, and each water tank leads to 1 to 2 water tanks. The water pipe is connected to the toilet water tank on the lower floor, and the sewage in the water tank has a relatively large odor, and the deodorization workload is large, the floor area is large, and the overall engineering effort is large, so it is difficult to popularize and implement on a large scale.

本发明采取的技术方案如图2所示，一种免附加水箱式公寓废水再利用系统，上层洗漱间副落水管10上至少设置有第一、二出水接口，第一出水接口通过第一连接管道11与下层卫生间冲便水箱20相连通连接，第二出水接口通过第二连接管道12与卫生间的主落水管相连通连接，下层卫生间冲便水箱20上还设有自来水进水管21，第一连接管道11上安装有可启闭的过滤装置30，第一、二连接管道11、12与上层洗漱间副落水管10连接处分别设置第一、二调节阀13、14。依靠楼层之间落差，上层洗漱间产生废水依靠势能直接注入下层的冲便水箱20。过滤装置30和第一连接管道11中需定期进行化学物质的除臭和清淤处理，确保不堵塞；上述提供的免附加水箱式公寓废水再利用系统，无需在各个楼层安装污水收集箱，污水在任何情况下都处于流动状态，不会造成大量污物的沉淀和沉积，有利于用化学和人工的方法进行除污处理，保证管道和环境的清洁。The technical solution adopted by the present invention is shown in Figure 2, a water tank-free apartment wastewater reuse system, the auxiliary downpipe 10 of the upper washroom is provided with at least the first and second water outlet interfaces, the first water outlet interface is connected through the first The pipeline 11 is connected with the toilet flushing water tank 20 of the lower floor, and the second water outlet is connected with the main downpipe of the bathroom through the second connecting pipe 12. The toilet flushing water tank 20 of the lower floor bathroom is also provided with a tap water inlet pipe 21, and the first connection An openable and closable filtering device 30 is installed on the pipeline 11, and first and second regulating valves 13 and 14 are respectively arranged at the joints between the first and second connecting pipelines 11 and 12 and the auxiliary downpipe 10 of the upper washroom. Relying on the drop between the floors, the waste water generated in the wash room on the upper floor is directly injected into the flushing water tank 20 on the lower floor by virtue of potential energy. The filter device 30 and the first connecting pipe 11 need to be regularly deodorized and desilted for chemical substances to ensure that they are not clogged; the tank-free apartment wastewater reuse system provided above does not need to install sewage collection boxes on each floor. Sewage is in a flowing state in any case, and will not cause a large amount of sedimentation and deposition of dirt, which is conducive to decontamination treatment by chemical and artificial methods to ensure the cleanliness of pipelines and the environment.
第一、二出水接头可通过在原有的上层洗漱间副落水管10出水端处安装一个三通形成。当学生在校时，关闭第二连接管道12上的第二调节阀14，打开第一连接管道11上的第一调节阀13，从而使污水只经第一连接管道11流入下层的冲便水箱20中；每间隔半个月对第一连接管道11上的过滤装置30进行清理，清理时打开第二调节阀14，关闭第一调节阀13，使污水流入卫生间的主落水管中。The first and second water outlet joints can be formed by installing a tee at the water outlet of the auxiliary downpipe 10 in the original upper floor wash room. When the students are at school, close the second regulating valve 14 on the second connecting pipe 12 and open the first regulating valve 13 on the first connecting pipe 11, so that the sewage only flows into the toilet flushing tank on the lower floor through the first connecting pipe 11 In 20; the filter device 30 on the first connecting pipe 11 is cleaned every half month, and the second regulating valve 14 is opened during cleaning, and the first regulating valve 13 is closed to allow sewage to flow into the main downpipe of the toilet.
进一步的方案为，上层洗漱间副落水管10的进水口处设置可拆卸的第一滤网15，过滤装置30出水口与第一连接管道11连接处设置可拆卸的第二滤网16，第一、二滤网15、16用以过滤生活废水中较大的固体杂质，滤网设计为可拆卸结构，以便定期对附着在滤网上的杂质进行清扫，实现对污水的一次过滤，第一过滤网15的网孔孔径为10nm，第二过滤网16的网孔孔径为5nm。下层卫生间冲便水箱20的自来水进水管21和出水管22上分别设置第一、二控制阀23、24，第一、二调节阀13、14为手动阀，第一、二控制阀23、24为电磁阀。过滤装置30包括一过滤水箱，过滤水箱内设置有可打开过滤器，过滤水箱上还有一层过滤组件，泥沙颗粒以及一些杂质颗粒由于重力，沉入过滤水箱底部，达到再次过滤的目的。由于过滤水箱可打开，所以定期可对其进行清理。下层卫生间冲便水箱20中采用红外对管检测装置进行水位检测。A further solution is to set a detachable first filter screen 15 at the water inlet of the auxiliary downpipe 10 in the upper washroom, and set a detachable second filter screen 16 at the connection between the water outlet of the filter device 30 and the first connecting pipe 11, and the first 2. The second filter screens 15 and 16 are used to filter larger solid impurities in the domestic waste water. The filter screens are designed as detachable structures, so as to regularly clean the impurities attached to the filter screens and realize the primary filtration of sewage. The first filter screen The mesh aperture of 15 is 10nm, and the mesh aperture of the second filter screen 16 is 5nm. The first and second control valves 23 and 24 are respectively arranged on the tap water inlet pipe 21 and the water outlet pipe 22 of the flushing water tank 20 of the toilet on the lower floor. The first and second control valves 13 and 14 are manual valves. The first and second control valves 23 and 24 for the solenoid valve. The filter device 30 includes a filter water tank, which is provided with a filter that can be opened. There is also a layer of filter assembly on the filter water tank. The silt particles and some impurity particles sink into the bottom of the filter water tank due to gravity to achieve the purpose of filtering again. Since the filter tank can be opened, it can be cleaned regularly. In the toilet flushing water tank 20 on the lower floor, an infrared pair of tube detection devices is used to detect the water level.
该系统还包括便池上方设置的对如厕人员进行数据采集的感应探头40以及控制装置50，控制装置50接收红外对管检测装置25和感应探头40采集的信号对系统各组件进行如下调控；The system also includes an induction probe 40 and a control device 50 arranged above the urinal to collect data from toilet users, and the control device 50 receives signals collected by the infrared tube detection device 25 and the induction probe 40 to regulate the components of the system as follows;
S1：若红外对管检测装置25检测到下层卫生间冲便水箱20内水位到达排水线则调节第二控制阀24打开进行排水，否则执行步骤S2；S1: If the infrared pipe detection device 25 detects that the water level in the flushing water tank 20 of the lower bathroom reaches the drain line, then adjust the second control valve 24 to open to drain water, otherwise, perform step S2;
S2：若感应探头40没有采集到如厕人员，则继续向下层卫生间冲便水箱20内注入废水，若感应探头40采集到有如厕人员，执行步骤S3；S2: If the induction probe 40 does not collect the person using the toilet, then continue to inject waste water into the toilet flushing tank 20 on the lower floor, and if the induction probe 40 detects that there is a person using the toilet, perform step S3;
S2：检测下层卫生间冲便水箱20内是否注满水，若没有注满水，调节打开第一控制阀23注入自来水；若注满水，调节第二控制阀24打开进行排水，关闭感应探头40，每隔1s对下层卫生间冲便水箱20内水位进行一次检测，至少检测65次，期间若下层卫生间冲便水箱20内水满则打开第二控制阀24排水，若不够则注入废水进行补充；如此循环重复执行步骤S1～S3，具体如图4所示。S2: Detect whether the flushing water tank 20 of the lower toilet is filled with water, if not filled with water, adjust and open the first control valve 23 to inject tap water; if filled with water, adjust the second control valve 24 to open for drainage, and close the sensing probe 40 , the water level in the flushing cistern 20 of the lower toilet is detected once every 1s, at least 65 times, during which if the water in the flushing tank 20 of the lower toilet is full, the second control valve 24 is opened to drain water, and if not enough, waste water is injected for supplementation; Steps S1-S3 are repeatedly executed in this way, as shown in FIG. 4 .
如厕人员检测采用现有的感应探头，当有人进入探测区域时，感应探头感测到人体信号，并向控制装置50发出电信号，反之，不采集；自来水注入管也采用现有的自来水注入管，因此，本发明提供的技术方案只需在现有的设备上进行一定的改造即可。The toilet personnel detection adopts existing induction probe, and when someone enters detection area, induction probe senses human body signal, and sends electric signal to control device 50, otherwise, does not collect; Tap water injection pipe also adopts existing tap water to inject Therefore, the technical solution provided by the present invention only needs to be modified to a certain extent on the existing equipment.
