Railway vacuum sewage unloading treatment system

Abstract

The invention discloses a railway vacuum sewage unloading treatment system which includes an excrement collection tank, a squeezing device and a cultured bacteria tank body. The excrement collection tank is connected to a vacuum suction device. The outlet of the vacuum suction device is connected to a primary filtering storage tank. A chamber, at the right side of a separation board, discharges a filtered waste liquid into a primary sedimentation liquid mixing tank through a second elastomer cam rotor pump. Waste materials, at the left side of the separation board, are connected to a first cutting machine. A crushed material outlet pipe of the first cutting machine is connected to a stirring disinfection chamber. The stirring disinfection chamber is connected to the squeezing device through a squeezing material feeding pipe. The outlet of a sterilizing cabinet is connected to a second cutting machine. A water outlet of the squeezing device is connected to a condenser through a first elastomer cam rotor pump. The bottom of the primary sedimentation liquid mixing tank is connected to the stirring disinfection chamber. One side of the primary sedimentation liquid mixing tank is connected to a waste liquid heating tank. Water vapor in the waste liquid heating tank is communicated with a water vapor condenser of the sterilizing cabinet. The system has simple structure, is high in sewage treatment efficiency, and can be widely promoted and applied.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of sewage discharge treatment, in particular to the technical field of railway vacuum sewage discharge treatment system. [0003] 【Background technique】 [0004] With the development of the times, many science and technology in our country have achieved the world's advanced level, among which high-speed rail is one of the high-tech, the current high-speed rail sewage is collected by vacuum toilets and pools to collect waste and waste liquid, and concentrate the excrement Inside the dirt tank under the train, it is transported away by a special sewage suction truck at the end of the train, which is particularly inefficient in treating feces, and at the same time increases the load of the train and affects the speed of the train, which is not in line with the national strategy of the Belt and Road Initiative In view of this situation, it is necessary to design a sewage treatment system for high-speed r...
