Problems solved by technology
However, the biochemical treatment unit of the device is too simple and can only simulate the AO process; moreover, the device is more focused on teaching and demonstration, without considering the function of optimizing the actual sewage production and operation
[0004] At present, the few sewage treatment pilot plants can only simulate a single biochemical treatment process, and their application functions are limited; moreover, most of the pilot plants are mainly used to determine the design parameters of new sewage plants, without considering the function of optimizing the production and operation of sewage plants , so the control means and range are relatively limited

Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0037] like Figure 1~4 As shown, the present invention is mainly composed of a reaction tank body, a pipeline system, a water outlet system, an aeration system and a sludge system. The reaction pool body is composed of reaction pools A, B, C and D, which are arranged in a straight line. Adjacent reaction pools share pool walls, and pools B, C, and D are adjacently connected by pipes. Pool A mainly simulates the anaerobic pool. Pool A adopts the water drop funnel 7 to discharge water to cut off the hydraulic relationship between pool A and the downstream reaction pool, and the effective water depth and volume of pool A can be adjusted by changing the height of the drop funnel 7, thereby Adjust the ratio of hydraulic retention time between pool A and the downstream reaction pool.
[0038]In this embodiment, the switching of the simulated proce...

The invention discloses a multifunctional pilot-scale test system for sewage treatment. The system consists of a first reaction tank, a second reaction tank, a third reaction tank and a fourth reaction tank which are arrayed in a line, wherein a stirring device is arranged in the first reaction tank and is used for mixing water flowing in the first reaction tank and backflow sludge or mixed liquid; the second reaction tank, the third reaction tank and the fourth reaction tank are respectively taken as an aerobic pond or a precipitation tank; stirring devices are respectively arranged in the three reaction tanks and are respectively used for mixing inflowing water and sewage in the tanks; and a triangular weir water outlet groove or a decanter for discharging water is arranged in each reaction tank, and an aeration system and / or a perforating dredging tube or a mud scraper is / are arranged in each reaction tank. The invention also discloses application of the multifunctional pilot-scale test system. The multifunctional pilot-scale test system can be used for simulating three series of processes, namely anaerobic-anoxic-oxic (AAO), sequencing batch reactor (SBR) and integral activate sludge process (UNITANK) and has a function of adjusting parameters on water quality of raw water, treatment scales, high resolution timer (HRT) proportions, sludge reflux quantity, mixed liquid reflux quantity and the like, thus meeting the various requirements on applied research and development for the sewage treatment.
Description
technical field [0001] The invention belongs to the technical field of water treatment, and relates to a sewage treatment pilot system for simulating various water treatment processes and an application thereof. Background technique [0002] In recent years, with the emphasis on environmental protection and the improvement of people's environmental awareness and environmental protection requirements, the research on urban sewage treatment technology has been deepened and extensive, and a large number of sewage treatment research and development, production and operation enterprises have emerged. Therefore, small-scale laboratory research can no longer meet the needs of actual scientific research, and domestic pilot plants have been established to simulate sewage treatment processes. [0003] Nanjing Kesheng Environmental Protection Technology Co., Ltd. provides a multifunctional sewage treatment pilot system for scientific research, display and teaching purposes (application...
