In the process of modern urban sewage treatment, the manure liquid receiving tank undertakes the task of collecting fecal and organic waste in domestic sewage, which is an indispensable link in the sewage treatment chain, and the special environmental conditions of the manure liquid receiving tank bring challenges to the liquid level measurement. This paper will analyze the characteristics of the manure receiving tank and analyze the application effect of radar level gauge in liquid level monitoring through actual cases.
The manure receiving tank usually has the following characteristics:1Contains high concentration of solid particles and suspended substances, which are easy to cause deposition and scaling. 2.The composition of the liquid is complex, including all kinds of organic matter, inorganic salts and microorganisms, and it has a certain corrosiveness. 3.Due to continuous input and intermittent discharge, the liquid level fluctuates frequently and with a large amplitude. 4.This is accompanied by the generation of gases such as methane and hydrogen sulfide, which can cause interference with the measuring device. 5.The harsh environment places higher demands on the corrosion resistance and protection level of the measuring equipment.
Radar level gauges are unique to the challenges of manure receiving tanks. It is based on the principle of microwave pulses, which emits microwaves to the liquid surface and receives the reflected waves to determine the liquid level. Its main advantages include high-precision measurements down to the millimeter level. Non-contact measurement that is unaffected by liquid corrosion and solid deposition. Easy to install and low maintenance. It is highly adaptable and can be used for level monitoring of a variety of complex media. In a city's sewage treatment plant, a radar level gauge with excellent performance was used for level monitoring in the manure receiving tank. The following are the main performance parameters of the device and the application situation:1High-frequency microwave with narrow beam angle ensures accurate signal focusing. 2.The wide measuring range can meet the needs of different sizes of manure receiving tanks. 3.The highly corrosion-resistant radome made of PTFE is highly resistant to harsh environmental influences. When installed, the radar level gauge is positioned precisely above the receiving cell and aligned vertically to the liquid level for optimal reflection. During operation, the device accurately records changes in the liquid level, and its real-time data provides reliable monitoring information for the central control room, thus achieving automatic control and optimal management.
An in-depth analysis of the characteristics of the manure receiving tank and the demonstration of the application effect of the radar level gauge through specific cases clearly show the great potential of the radar level gauge in the level monitoring of the manure receiving tank. Its accuracy, stability and low maintenance costs make it the technology of choice in wastewater treatment.
