Description

Technical Field

[0001] The invention belongs to the field of testing equipment, and in particular relates to a low-carbon biochemical treatment pilot device for a water purification plant. Background Art

[0002] The existing water treatment processes include continuous flow AAO, multi-stage A / O, AOA and other process flows. Before water quality treatment is carried out through different process means, it is often necessary to verify the treatment effect through experiments, usually through small-scale test equipment. The existing small-scale test equipment has the characteristics of poor equipment reuse effect and strong specialization. After assembly, it is difficult to be used for testing a certain process flow. When conducting multiple frequency tests of water quality, the equipment assembly cost is relatively high. This application aims to design a low-carbon biochemical treatment small-scale test equipment for water purification plants, which can be applied to a variety of detection process flows and avoid interference from water quality pollution between multiple tests. Summary of the Invention

[0003] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and propose a low-carbon biochemical treatment pilot test equipment for a water purification plant, which can be applied to a variety of detection processes and avoid contamination of the detection equipment during the switching process to ensure the accuracy of the test.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a small-scale low-carbon biochemical treatment pilot plant equipment for a water purification plant, comprising a box body, a box cover provided on the box body, six test water tanks provided on the box cover, two adjacent test water tanks connected by a connecting pipe, a first solenoid valve provided in the middle of each connecting pipe, a first water inlet provided on the upper side of the side wall of one of the test water tanks located at the edge, a sludge return port provided on the lower side of the first water inlet, and a first water outlet provided on the lower side of the side wall of another test water tank located at the edge, a first hydraulic cylinder fixed on the side wall of each test water tank, a sealing plate fixedly connected to the output end of the first hydraulic cylinder, and the sealing plate capable of sealing the upper end of the test water tank. Traditional small-scale test equipment only meets a single test mode, such as continuous flow AAO, multi-stage A / O, and AOA. When dealing with different tests, multiple sets of small-scale test equipment are required. The present equipment can switch the bottom blocking form and the top capping state, so that a set of small-scale test equipment can adapt to multiple test processes.

[0005] As a preferred embodiment of the present invention, a water inlet pipe is provided at the upper end of each sealing plate, and each water inlet pipe is connected to a second solenoid valve. The water inlet pipe connects the test water tank and the clean water pipe, and is controlled by a valve to switch between the test water and the clean water, and the return port is controlled by the second solenoid valve.

The sludge is discharged through the second outlet and then returned through the sludge return port. The first three are anoxic / anaerobic tanks, and the last three are aerobic tanks. When a test is completed and the test process needs to be switched, the second drive motor drives the second pulley to rotate, which in turn drives the first pulley, which in turn drives the turret to switch the aerobic / oxygen state of the pool. At the same time, clean water is injected through the sealing plate to flush the equipment and remove any residue from the previous test. Then, the corresponding sealing state is adjusted to switch to a multi-stage A / O test. At the same time, the AOA process flow test mode can be switched by leaving the pool empty and opening and closing the aeration port.
