Description
Technical Field
The invention relates to the field of non-full flow pipeline systems, in particular to a non-full flow pipeline system convenient to disinfect.
Background
Industrial sewage treatment plants: the industrial sewage treatment mainly aims at chemical substances which seriously affect the environment and comprehensively filters discharged waste residue liquid. Compared with domestic sewage, the industrial sewage has more complex components, higher pollution degree and higher treatment difficulty.
A domestic sewage treatment plant: the domestic sewage treatment mainly aims at a biochemical part, which is a conventional biochemical treatment process, and comprises a conventional activated sludge treatment process, an anaerobic-anoxic-aerobic process (A2O), an anaerobic-anoxic (A/O) and a Sequencing Batch Reactor (SBR).
The industrial sewage treatment corresponds to different industrial types of industries, such as textile industry, leather industry, paper making industry and the like, the textile industry is divided into various sub-industries, such as cotton textile, wool textile, hemp textile, silk textile and chemical fiber textile, the sub-industries are divided according to working procedures and comprise dyeing, printing, hemp degumming, silk reeling and the like, and the industrial wastewater generated by different working procedures in different industries contains various pollutants, so that the sewage disposal is different. The same treatment process is generally adopted in the domestic sewage treatment plants, the industrial sewage treatment plants in industrial cluster areas of various industrial parks have various characteristics, and all industrial sewage cannot be treated by only one treatment process, which is the most essential difference from the domestic sewage treatment plants.
The ultraviolet disinfection is widely applied to urban drinking water, effluent of urban sewage treatment plants, water for recycling urban sewage and industrial wastewater treatment stations. The ultraviolet ray is electromagnetic wave with wavelength of 100 nm-380 nm, the ultraviolet wave band with disinfection capacity is 200 nm-280 nm, after pathogenic microorganism absorbs ultraviolet energy with wavelength of 200 nm-280 nm, its genetic material (nucleic acid) is mutated to make cell no longer divide and reproduce, so that the goal of disinfection and sterilization can be reached.
When tail water of a sewage and wastewater treatment plant is disinfected by ultraviolet rays, the tail water is mostly in a gravity non-full-flow state, the change of the water yield of the tail water is large all the year round, and an open channel type ultraviolet disinfection system is generally adopted. The open channel type ultraviolet disinfection system occupies a large area, is open in operation boundary conditions, and is easily influenced by external conditions, and peripheral sundries enter to influence the disinfection effect. The open channel type ultraviolet disinfection system has better operation effect in a sewage and wastewater treatment plant with perfect management, high professional quality of operators and larger scale. However, when the sewage treatment plant with a small scale and a small town level is operated, the technical strength of operators is weak, the management is not in place, the pollution is easy, the disinfection effect is influenced, the quality of effluent water is unstable, and potential safety hazards exist. Tubular ultraviolet ray disinfection equipment has that to take up an area of for a short time, simple to operate, advantage such as being difficult for receiving external conditions influence during operation, but during operation ultraviolet lamp need totally submergence, and the pipeline need be in full flow state, so hardly direct application is in the non-full flow pipeline of gravity.
