Description

Technical Field

[0001] The present application relates to the technical field of water quality detection, and in particular to a monitoring device for sewage treatment. Background Art

[0002] In order to avoid further pollution of water resources, sewage treatment equipment is generally used to filter and decompose domestic sewage and industrial drainage so that the treated water will not cause harm to the environment.

[0003] Sewage treatment equipment is an industrial device that can effectively treat sewage and prevent sewage and pollutants from flowing directly into water bodies, which is of great significance to improving the ecological environment. In order to ensure that the treated sewage meets the discharge standards and to promptly detect any problems with the sewage treatment equipment to ensure the normal operation of the sewage treatment equipment, it is necessary to monitor the sewage treatment. For example, a sewage treatment monitoring device with publication number CN211652819U relates to the field of sewage treatment. To address the problem that the turbidity level in the existing sewage treatment process cannot be effectively monitored, the prior art proposes the following solution, which includes a filter box, a computer electrically installed at the top of the filter box, an inlet pipe and an outlet pipe respectively installed at the water inlet and outlet of the filter box, a filter screen installed at the water outlet, and a flow meter installed on the outlet pipe. The interior of the filter box is equipped with an inclined blanking plate that rotates via a rotating shaft, and a torsion spring is installed at the rotating shaft. An electronic scale is installed on the inner wall of the bottom end of the filter box, and a filter plate is installed on the top of the electronic scale. A sleeve is hinged to the inner wall of one side of the filter box, and a spring is fixedly connected to the sleeve. The existing technology has a novel structure, can effectively monitor sewage in real time, obtain its turbidity level in a timely manner, and grasp the latest data, and is suitable for promotion.

[0004] However, the above existing technologies still have some defects when monitoring sewage treatment:

[0005] 1. Sewage contains a complex mixture of various forms of inorganic and organic matter. In addition to floating and suspended solid particles of various sizes, there are also pollutants such as carbohydrates and proteins that are dissolved in the sewage. The above-mentioned prior art filters the sewage entering the filter box through the feed pipe through a filter screen, and the sewage falls on the top of the drop plate. When its weight reaches a certain level, the filtered material on the drop plate falls to the top of the filter plate and is weighed by an electronic scale. At the same time, the sewage volume is monitored by a flow meter, and the signal is transmitted to a computer for calculation and display, thereby effectively monitoring the sewage turbidity during the sewage treatment process and obtaining sewage data in a timely manner. However, the above-mentioned prior art can only monitor the content of solid suspended particles in the sewage, but cannot monitor the content of soluble pollutants dissolved in the sewage, resulting in an inability to fully monitor the sewage treatment process and an inability to fully understand the sewage pollution situation.

[0006] 2. During the sewage treatment process, the sewage volume and pollutant content often change at different times. When the sewage treatment process is monitored by the above-mentioned existing technology, when a large change in the pollutant content in the sewage is detected, the operator needs to manually adjust the sewage treatment equipment according to the monitoring results, including adjusting the operating parameters of the sewage treatment equipment, increasing or decreasing the dosage of the treatment agent, or changing the treatment process flow, etc.; and, in order to ensure the normal operation and long-term stability of the equipment, the operator also needs to adjust and inspect the sewage treatment equipment at any time according to the monitoring results, which increases the operating process and operating costs, and the manual adjustment may be inaccurate, resulting in the sewage treatment results not meeting the emission standards.

[0007] Based on this, and in accordance with the above-mentioned viewpoints, there is still room for improvement in the existing technology for monitoring sewage treatment. Utility Model Content
