Embodiment Construction

[0017] see figure 1 and figure 2 , the specific implementation of the pressure tubular sewage treatment reactor is as follows: the reactor includes negative pressure oxygenation equipment 1, pressure tubular reaction zone 2, filler input port 3, safety valve 4, pressure regulating valve 5, drain pipe 6, Mud discharge pipe 7 and exhaust valve 8 etc. The inlet water of the reactor is pressurized by the water pump 11, through the negative pressure oxygenation equipment 1 negative pressure oxygen inhalation, carrying a large amount of oxygen into the pressure tube reaction zone 2, and using the pressure regulating valve 5 on the water inlet pipe of the reaction zone to control the reaction work pressure in the area. The pressure reaction zone is composed of multiple pipe sections, each section is separated by a partition 9, and a suspended packing 10 is installed in the pipe through the filling opening 3. The gas produced by the anaerobic fermentation in the reaction zone is d...

Abstract

The patent refers to the field of 'treatment of water, waste water, sewage, or sludge'. The invention discloses a negative pressure oxygenated pressure pipe type sewage treatment reactor, composed of two parts of negative pressure oxygenation and pressure pipe type reaction zone. Reactor water inflow is pressurized by a water pump firstly, and negative pressure oxygenation is carried out to carry massive oxygen into the pressure pipe type reaction zone. The reaction zone is composed of a plurality of pipe sections which are horizontally arranged, suspension filler is arranged in the interior, and a grating is arranged at the middle for separation. Meanwhile the water inlet pipe at the front end of pipeline is provided with a pressure regulating valve, so as to regulate and control pressure in the pipe, the top is provided with a vent valve, a safety valve and a filler feeding hole, the bottom is provided with a discharge pipe, the terminal is provided with a drain pipe, and the treated sewage is discharged to nearby water body. The treatment reactor integrates sewage conveying and treatment functions into a whole and has the advantages of good sanitary condition, strong impact load resistance, high treatment efficiency, low operating energy consumption, less residual sludge and simple process.

Description

technical field [0001] The invention belongs to the technical fields of sewage treatment and environmental protection, and in particular relates to a pressure tube type sewage treatment reactor. Background technique [0002] At present, conventional urban sewage treatment facilities require large investment, high operating costs, and complex operation and management, making it difficult to promote them in small towns. In recent years, the reactor technology for small town sewage treatment has developed rapidly. For example, 200420061308.9 "Six-dimensional three-phase biological treatment process device", 03129146.5 "A small town sewage treatment process" and 200520009231.5 "Baffle Wetland filter + lateral subsurface flow wetland bed sewage treatment system" and so on, all three are atmospheric sewage treatment processes, which are quite different from this pressurized reactor. In order to achieve higher treatment efficiency, the process flow is longer , the structure is rel...
