The severe cold climate in the northern region has a great impact on people's lives and production. The formation of this severe cold climate is related to factors such as geographical location, climatic conditions, and natural environment. The northern region is located at high latitudes and receives less solar radiation, so the temperatures are lower in winter. There are many mountains and hills in the northern region, and the terrain is complex, which is prone to the formation of cold snaps and cold air, which leads to a sharp drop in temperature. In addition, the northern region has less vegetation and a larger bare area of soil, which is also prone to a drop in temperature.
The coldest time in the northern region can reach minus 30-40 degrees, so what is the impact of cold weather on sewage treatment?
Low temperatures reduce the rate of biological treatment reactions. Because low temperature will cause slow microbial growth and enzymatic reaction rate, it will inevitably lead to a decrease in activated sludge activity, so that the biological treatment reaction rate will decrease.
In view of the impact of the severe cold climate in the north on sewage treatment equipment, the following are some suggestions:
Equipment selection and design: In the selection and design stage of sewage treatment equipment, the climatic characteristics of the northern region should be fully considered, and the equipment model and configuration suitable for the cold environment should be selected. For example, the selection of low-energy, high-efficiency sewage treatment equipment can reduce operating costs and improve the performance of equipment in low-temperature environments.
Thermal insulation measures: For pipes, valves and other equipment that cannot be avoided from being exposed, thermal insulation measures should be taken, such as wrapping with thermal insulation materials, to reduce heat loss and maintain the normal operation of the equipment. In addition, an electric heating system or steam heating system can be installed to insulate critical areas and prevent equipment from freezing or freezing.
Maintenance and maintenance: Before the onset of winter, comprehensive maintenance and overhaul of sewage treatment equipment should be carried out to ensure that the equipment is in good operating condition. At the same time, the inspection and inspection of equipment should be strengthened to find and solve potential problems in a timely manner. For critical parts, such as aerators, water pumps, etc., regular care and maintenance should be carried out to ensure their normal operation.
Energy saving and consumption reduction: On the premise of ensuring the effect of sewage treatment, energy consumption should be reduced as much as possible, such as choosing high-efficiency and low-energy consumption motors, and reasonably adjusting the aeration capacity. In addition, renewable energy sources such as solar and wind energy can be considered to replace part of the energy consumption.
Remote monitoring and intelligent management: Through the remote monitoring system and intelligent management platform, the operation status and various parameters of the sewage treatment equipment can be monitored in real time, and problems can be found and solved in time. At the same time, the equipment can be remotely controlled and adjusted through the intelligent management platform to improve the operation efficiency and management level of the equipment.
The overall shape of the shell adopts a rounded double-layer structure with a large surface and an integrated preferred insulation material on the inside, which can easily cope with the extremely cold weather in the north, and the maximum temperature resistance can reach -20. Solar + mains dual function, extremely power-saving, suitable for use in the northern cold and dispersed areas.
