The "sanitary wastewater" here refers specifically to wastewater used to discharge sanitary wastes. The sanitary wastes include excrement, urine and kitchen waste, but do not include washing wastewater such as bathing, laundry, and kitchen rinsing. Here, "suction discharge" includes the process of transferring sanitary wastewater from sanitary ware to the location of storage, discharge or treatment, but does not include the process of storage, discharge or treatment. When the pressure in the suction pipe is lower than the external atmospheric pressure, the sanitary ware is connected with the suction pipe, so that the sanitary waste water in the sanitary ware is sucked into the suction pipe and transported to the far end, so as to realize the discharge function of sanitary waste water. Compared with the water-flushing sanitary discharge method that relies on hydraulic self-weight to realize pipeline transportation, suction sewage has the advantages of water saving, energy saving and consumption reduction, especially the low-dilution collection of sanitary wastes such as feces and urine can be realized for subsequent resource utilization. Processing utilization creates favorable conditions.

为使本公开的目的、技术方案和优点更加清楚明白，以下结合具体实施例，并参照附图，对本公开作进一步的详细说明。In order to make the objectives, technical solutions and advantages of the present disclosure more clearly understood, the present disclosure will be further described in detail below with reference to specific embodiments and accompanying drawings.
在抽吸排污的相关技术中，通常需要构建一个由抽吸管道、储存容器、界面阀和真空泵等组成的抽吸管道***，该抽吸管道***内的压强常态化地低于外界大气压，亦即维持真空度或负压状态，其中界面阀和真空泵分别处于抽吸管道***与外界大气压的边界位置，真空泵还提供了将抽吸管道内部的气体等强制排出抽吸管道***的动力，以维持***内的压强低 于大气压。该抽吸管道***有以下几个特点：(1)维持真空度或负压状态对密封的要求很高，若出现漏气现象，轻则浪费能源，重则使***失效；(2)卫生废水从处于大气压环境的卫生洁具直达处于大气压环境的储存、处理或利用设施，中间只经过处于负压环境的抽吸管道***，由此为了使卫生废水从负压环境转移至大气压环境需要采取额外的措施，比如破除负压或使用高扬程的排污泵将抽吸管道内的卫生废水强制排出。由此造成该抽吸排污技术在实际应用中的几点不足：(1)对真空泵站的要求比较高，增加了泵站建设与运行的成本；(2)对抽吸管道的密封要求比较高，增加了管道敷设和维护的成本；(3)用户端的卫生洁具需要通过特制的排污界面阀连接抽吸管道，并因此通常导致需要在用户端使用特制的卫生洁具；(4)由于抽吸管道中通常维持较高的负压，在用户端打开排污界面阀的瞬间会产生强烈的吸气噪声，影响用户体验。当上述抽吸排污技术应用于诸如乡村环卫这样的场景时，由于乡村居住比较分散，集中设置的泵站和抽吸管道***的成本尤其高。In the related technologies of suction and sewage, it is usually necessary to construct a suction pipeline system composed of suction pipelines, storage containers, interface valves and vacuum pumps. The pressure in the suction pipeline system is normally lower than the external atmospheric pressure, and also That is to maintain the vacuum degree or negative pressure state, in which the interface valve and the vacuum pump are respectively at the boundary position between the suction pipeline system and the external atmospheric pressure. The pressure in the system is below atmospheric pressure. The suction piping system has the following characteristics: (1) Maintaining vacuum or negative pressure has high requirements for sealing. If there is air leakage, energy will be wasted in light, and the system will fail in heavy; (2) Sanitary wastewater From the sanitary ware in the atmospheric pressure environment to the storage, treatment or utilization facilities in the atmospheric pressure environment, only through the suction pipeline system in the negative pressure environment, so in order to transfer the sanitary wastewater from the negative pressure environment to the atmospheric pressure environment requires additional measures Measures, such as breaking the negative pressure or using a high-lift sewage pump to forcibly discharge the sanitary wastewater in the suction pipe. As a result, there are several deficiencies in the practical application of the suction and sewage technology: (1) The requirements for the vacuum pumping station are relatively high, which increases the cost of construction and operation of the pumping station; (2) The sealing requirements for the suction pipeline are relatively high. , increasing the cost of pipe laying and maintenance; (3) the sanitary ware at the user end needs to be connected to the suction pipe through a special sewage interface valve, and thus usually leads to the need to use a special sanitary ware at the user end; (4) due to the suction pipe Generally, a relatively high negative pressure is maintained in the middle, and a strong inhalation noise will be generated at the moment when the sewage interface valve is opened at the user end, which will affect the user experience. When the above-mentioned suction and sewage technology is applied to scenarios such as rural sanitation, the cost of centralized pumping stations and suction piping systems is particularly high due to scattered rural residences.
在实现本公开的过程中，发现在将室内卫生洁具内的卫生废水转移至室外的过程中，利用在排污管道上设置连通大气压环境的拔风组件，所述的排污管道是指连接室内卫生洁具和室外排放、处理、利用设施的管道***，开启该拔风组件在该排污管道内产生瞬时负压，将卫生洁具内的卫生废水吸入管道，然后关闭拔风组件以使排污管道恢复大气压环境，然后将卫生废水在重力作用下从排污管道内卸离，由于利用的是这种瞬时负压而无需维持负压状态，无需通过界面阀将卫生洁具与排污管道相连，可广泛适用于常规卫生洁具，降低了对于排污管道密封的要求，避免了泵站建设的需要，降低了泵站建设与运行、管道敷设与维护的成本，可应用于例如乡村环卫这种居住分散的场合中。In the process of realizing the present disclosure, it was found that in the process of transferring the sanitary waste water in the indoor sanitary ware to the outdoors, a blow-off component connected to the atmospheric pressure environment was arranged on the sewage pipeline, and the sewage pipeline refers to the connection of the indoor sanitary ware. And the pipeline system of outdoor discharge, treatment and utilization facilities, open the air extraction component to generate instantaneous negative pressure in the sewage pipeline, suck the sanitary waste water in the sanitary ware into the pipeline, and then close the air extraction component to restore the sewage pipeline to atmospheric pressure environment, Then, the sanitary wastewater is discharged from the sewage pipeline under the action of gravity. Since this instantaneous negative pressure is used, it is not necessary to maintain a negative pressure state, and there is no need to connect the sanitary ware to the sewage pipeline through an interface valve, which can be widely used in conventional sanitary ware. , reducing the requirements for the sealing of sewage pipelines, avoiding the need for pumping station construction, reducing the cost of pumping station construction and operation, pipeline laying and maintenance, and can be used in scattered places such as rural sanitation.
