Feasibility Study On Domestic Wastewater Pressure Flow System

For a long time, the position of the drainpipes in our kitchen and toilet are below the floor. To put it more specifically, each drainpipe of the sanitary ware must drill through the floor to the space which belong to the tenement next down, and then all the drainpipes were connected with a horizontal drainpipe with slope, finally into a vertical drainpipe. This is the typical uncompletely traditional gravitational flow system. However, followed by the idea of comfort and health, the traditional system has many disadvantages. The higher the living level grows, the better standard of the design and the quality of the constraction were needed by people nowadays. Most of all, when they start to economize the power and protect the environment, people are tend to new adopt lifestyle. Therefore more and more new technique of drainage systems are emerged. The pressure flow system is one of them which become the hot spot of the study lately.The pressure flow system is totally different from the traditional system.The entire system consists of:the sanitary ware, the sullage tank, the pumping, the pipe with pressure and some special accessories. The combined system varies much from the traditional vertical system:the pipes have no gradient and sometimes even contradictorily gradient. The diameter of the pipe is thinner and thinner, and the pump can make pressure flow instead of the gravitational flow. All the excellence make the system simple, small and easy to maintain. When people using the pressure flow system. They will feel very convenient and comfortable. Also, the system keep the environment inside the house nice and clean.With the dense interest of the pressure flow system, the auther has built a 4-meter-high platform which made of steel in limited condition. According to the custom, there are some sanitary wares set on the platform:seat toilet bowl, wash basin, and bathtub. After several ways of combination, there are some different systems. In term of the habit of rinsing and washing, the write have done many experiment on the system. In order to find the best way of the combining, the efficiency and effect of the system must be considered, and based on the results of the experiment, one of the system has choised as the best scheme.The pressure flow system in the building appear to be a brand-new sewerage. However, with the traditional concept there must be a tough and long road for the new system to be accept by all people. So necessary report and experiment should be done by the expert and research institude. Also, investment from some enterprise and organization is needed urgently.As the worldwide deficiency of water resource was coming, our country and society are encouraging to save water, protect the environment and people-oriented. The raising of the country synthesize strength and people's living standard. In addition, the science and technology level are also developing fast. We can say that the people's concept will change very soon and the pressure flow system will be accepted in a short time. Beside, the pressure flow system outside the house was used in many places in our country. In that way, the system inside the house must be given more attention. As a result, we can use this system to make our life and society more and more better.
