Embodiment 1

[0044] The following process is used to treat a certain organic sewage, and the effluent is required to meet the discharge standard.

[0045] Raw sewage→regulating tank (A)→pump→UASB→activated sludge anoxic tank→activated sludge aeration tank→vertical sedimentation tank→discharge→biofilm anoxic tank→contact oxidation tank→mixed reaction tank→incline pipe Sedimentation tank → discharge

[0046] (1) Technological process and experimental principle

[0047] The sewage in the regulating tank (A) is pumped into the UASB reactor for anaerobic degradation to remove most of the organic matters. The UASB outlet water flows into the activated sludge anoxic tank and the biofilm anoxic tank respectively, and is mixed with the nitrification liquid returned from the activated sludge aeration tank and the contact oxidation aeration tank respectively to carry out denitrification reaction and remove the sewage nitrogen and some organic matter. The effluent from the activated sludge anoxic t...

Embodiment 2

[0066] Use the following operation mode to treat two kinds of organic sewage at the same time, conduct two experiments on the same device at the same time, and require the effluent to meet the discharge standards.

[0067] Raw sewage 1→regulating tank (A)→pump→UASB→discharge

[0068]

[0069] (1) Technological process and experimental principle

[0070] ①Experiment 1

[0071] The raw sewage 1 in the regulating tank (A) is pumped into the UASB reactor for anaerobic degradation, and the organic matter is removed before being discharged.

[0072] ②Experiment 2

[0073] The raw sewage in the regulating tank (B) is pumped into the activated sludge anoxic tank and the biofilm anoxic tank respectively in two ways, and mixed with the nitrification liquid returned from the activated sludge aeration tank and the contact oxidation aeration tank respectively, and then Denitrification reaction to remove nitrogen and some organic matter in sewage. The effluent from the activated slud...

Abstract

The invention relates to an experimental apparatus of water processing, in particular to a multifunctional combination experimental apparatus of automation biological treatment of sewage, which can be used for teaching and scientific researching. The apparatus integrates a plurality of basic technical units of sewage biological treatment as a whole, can combine each unit into more than 40 different treatment techniques, can combine techniques that run at the same time into more than 40 different running modes, and not only can carry out running of an individual technical unit or single technique, but also run different techniques according to a running mode and carry out different experiments .The apparatus can not only be operated by hand, but also can automatically produce running techniques, running modes through computer operation, automatically run and automatically give a alarm. The apparatus can be used for carrying out a plurality of technological experiments on sewage biological treatment and water outlet can reach standards of advanced treatment. During experiment, operational parameters are detected online and automatically adjusted and controlled by a computer. Detected data can be displayed, recorded and inquired by the computer.

Description

technical field [0001] The invention relates to a water treatment experimental device, in particular to a multifunctional automatic sewage biological treatment combined experimental device, which can be used for teaching and scientific research. Background technique [0002] At present, the experimental devices used in water treatment teaching and scientific research are unit operation or single process type, and can only conduct experimental research on a certain independent technical unit or a single process flow, and cannot combine various technical units into different types on the same device. different treatment processes, and it is not possible to run different treatment processes on the same device at the same time for different experiments. Computer operations and automated operations cannot be performed. Many operating parameters cannot be detected online, and automatic adjustment and control of operating parameters cannot be performed through a computer. The det...
