In the process of modern urban wastewater treatment, the fecal liquid receiving tank undertakes the task of collecting feces and organic waste in domestic sewage, which is an indispensable link in the wastewater treatment chain, and the special environmental conditions of the fecal liquid receiving tank bring challenges to the liquid level measurement.
In this paper, we will discuss the characteristics of fecal liquid receiving tank and analyze the application effect of radar level meter in liquid level monitoring through practical cases.
Manure receiving tanks usually have the following characteristics:
1. They contain a high concentration of solid particles and suspended substances, which are easy to cause deposition and scaling.
2. The liquid composition is complex, containing various types of organic matter, inorganic salts and microorganisms, and has a certain degree of corrosiveness.
3. Due to continuous input and intermittent discharge, the level fluctuates frequently and with a large amplitude.
4. It is accompanied by the generation of gases, such as methane, hydrogen sulfide, etc., which may cause interference with the measuring equipment.
5. The environment is harsh, which puts more demands on the corrosion resistance and protection level of measuring equipment. Measurement equipment. The harsh environment places higher demands on the corrosion resistance and protection level of the measurement equipment.
The radar level meter meets the challenges of fecal liquid receiving tanks with its unique advantages. It is based on the microwave pulse principle, emitting microwaves to the liquid surface and receiving reflected waves to determine the level. Its main advantages include: high accuracy measurement down to the millimeter level. Non-contact measurement method, unaffected by liquid corrosion and solid deposition. Easy to install and low maintenance costs. Strong adaptability, can be used for a variety of complex media level monitoring.
In a city’s wastewater treatment plant, the level monitoring of the fecal liquid receiving tank uses a radar level meter with excellent performance. The following are the main performance parameters and applications of the device:
1. High-frequency microwave, with a narrow beam angle, to ensure the accurate focusing of the signal.
2. A wide range of measurement, to meet the needs of different sizes of fecal liquid receiving tanks.
3. Highly corrosion-resistant antenna cover made of PTFE, effectively resisting the impact of harsh environments.
4. The radar level meter is installed in the tank of a municipal wastewater treatment plant.
During installation, the radar level meter is accurately positioned above the receiving tank and vertically aligned to the liquid surface for optimal reflection.
During operation, the device accurately records liquid level changes, and its real-time data provides reliable monitoring information for the central control room, thus realizing automated control and optimized management.
By analyzing the characteristics of manure receiving tanks and demonstrating the application of radar level meters through specific cases, we can clearly see the great potential of radar level meters in monitoring the level of manure receiving tanks. Its accuracy, stability and low maintenance costs make it the technology of choice in the field of wastewater treatment.
