Embodiment 1

[0017] Example 1, the device is transformed into a biological fluidized bed, the rubber hose is set on the sampling port 2, and the hose is clamped with a clamp to seal the sampling port 2. If two or more types are used, the filler needs to be placed into the corresponding casing 3, and then put it into the cylinder, (if a single filler is used, the casing 3 can be taken out, and the filler can be directly put into the cylinder), and the sewage enters from the lower inlet / outlet 4 respectively, The air enters from the air inlet 5, making the carrier in a fluidized state in the cylinder, and the treated water samples flow out from the upper water inlet / outlet 1. Such as dealing with COD cr When the domestic sewage is about 230mg / L, in order to facilitate the growth of microorganisms, two kinds of fillers, coal-based activated carbon and zeolite, are selected and put into corresponding casings respectively. The influent flow rate is controlled at about 10ml / min, and the treatmen...

Embodiment 2

[0018] Embodiment 2, the device is converted into a filter device, the air inlet 5 and the sampling port 2 are covered with rubber hoses, the hoses are clamped with clips, and it is closed. If only a single filter material is required, the sleeve pipe 3 Take it out and put the filter material directly into the cylinder. If activated carbon, zeolite, quartz sand and other different filter materials are used, the different filter materials can be put into the corresponding casing 3, and the sewage can be selected from the upper water inlet / outlet according to needs. 1 or the bottom inlet / outlet 4 enters or discharges, and when it is necessary to measure the filtration effect at different heights, open the clamp and take samples from the sampling ports 2 at different heights;

Embodiment 3

[0019] Example 3, the device is converted into an anaerobic column, and several rubber hoses are respectively placed on the sampling port 2 and the upper right inlet / outlet 1, and these hoses are clamped with clips, and the sampling port 2 and the upper right inlet / outlet The outlet 1 is closed, and the packing sleeve 3 can be used or taken out according to the needs. The air inlet 5 is fed with inert gas such as nitrogen to make the inside of the cylinder in an anaerobic state. Measure the temperature in the anaerobic state in the cylinder at any time, and at the same time connect the mouth of the air guide pipe with a hose to perform water sealing and exhaust, and the sewage enters from the bottom inlet / outlet 4, so that the sewage fills the entire cylinder;

Abstract

The invention relates to an multi-functional sewage disposal experimental apparatus and an application thereof, which is characterized in that the apparatus is a long column type cylinder provided with a base; a plurality of sample connections provided with a filter screen are arranged on a wall of the cylinder; a water outlet / inlet is arranged on the upper right side of the wall of the cylinder; the water outlet / inlet is arranged on the lower left side of the wall of the cylinder; a gas inlet is arranged on the bottom of the left side of the wall of the cylinder; a plurality of filter material bushings which can be freely assembled and disassembled are arranged in the cylinder; the bottom of the bushing is provided with supporting legs; a rubber plug provided with a thermometer and a gas-guide tube is arranged on the upper part of the cylinder. The apparatus of the invention has the advantages of that a physical method, a chemical method and a biological method used commonly in the sewage disposal are freely combined so as to change freely the apparatus into the sewage disposal experimental apparatus with the different functions such as a biological fluid bed, a filtrating equipment, an anaerobic column, an active charcoal absorbing column and an ion exchange column, etc. The apparatus of the invention fully stimulates an innovative enthusiasm of users, meets different usage requirements, fosters a multi-thinking of students and improves ability of thinking and practicing of the student. The multi-functional sewage disposal experimental apparatus also has the advantages of novel structure, small occupied space, cheap fabrication cost, thereby being applied to an experimental teaching and a scientific research extensively.

Description

technical field [0001] The invention is a multifunctional sewage treatment experimental device, which can freely combine physical, chemical and biological processes and comprehensively apply it to the experimental research of sewage treatment, and can be widely used in the fields of environmental science, physical chemistry and other experimental teaching and scientific research. It belongs to the technical field of teaching experiment instruments. Background technique [0002] In recent years, small and medium-sized sewage treatment devices developed for experimental teaching and scientific research have emerged in an endless stream, but these devices often have disadvantages such as single function, difficult modification according to actual needs, large floor area, and relatively expensive prices, which to some extent restrict The study of sewage treatment process is not conducive to the cultivation of students' multiple thinking ability.
