Tofoe Technology tells you about the problems currently faced by sewage treatment equipment in China?
+At present, China's sewage treatment equipment is facing heavy pollution loads, traditional treatment methods are inefficient, have a significant impact on the receiving water body, and have strong persistence; The processing technology is complex, the operating cost is high, the one-time infrastructure investment is large, and the burden on enterprises is heavy. At present, the recycling rate of industrial wastewater in China is low, and there is a significant gap compared to developed countries, which exacerbates the contradiction of water resource shortage and water environmental pollution in China. -
What process methods can be used in industrial wastewater treatment projects?
+Industrial wastewater treatment methods can be divided into four categories based on their principles of action, namely physical treatment, chemical treatment, physicochemical treatment, and biological treatment. The selection of process plan should be based on the actual water quality, including effluent quality (COD, SS, BOD, etc.). -
What general precautions should be taken during the operation of water pumps in industrial wastewater treatment equipment?
+1. Check if all instruments are working properly and stably, paying special attention to whether the ammeter exceeds the rated current of the motor. If the current is too high or too low, stop the machine immediately for inspection.2. Check if the flow rate of the water pump is normal. When installing a flowmeter, check if the flow rate indicated by the flowmeter is normal or estimate the flow rate based on the current of the ammeter, the flow rate of the outlet pipe, and the change in the water level of the collection well.
3. Check if the packing pressure plate of the water pump is heating up and if the dripping is normal.
Pay attention to the sound and vibration of the unit.
Pay attention to the temperature rise of the bearing, generally not exceeding 35 ℃ of the surrounding ambient temperature.
6. Check the temperature rise of the motor, and if it is too high, stop the vehicle for inspection.
Check whether the water pump and pipeline are leaking.
Check if the water level in the collection well is too low and if the grille or inlet is blocked.

What are the problems currently faced by China's sewage treatment engineering system?
+At present, China's sewage treatment engineering system is facing heavy pollution loads, traditional treatment methods are inefficient, have a significant impact on the receiving water body, and have strong persistence; The processing technology is complex, the operating cost is high, the one-time infrastructure investment is large, and the burden on enterprises is heavy.

Why is there residual sludge generated in industrial wastewater treatment projects?
+In the biochemical treatment process of industrial wastewater treatment engineering, microorganisms in activated sludge continuously consume organic matter in the wastewater. In the consumed organic matter, a portion of the organic matter is oxidized to provide the energy required for microbial life activities, while another portion is utilized by microorganisms to synthesize new cytoplasm, thereby promoting microbial reproduction. While microorganisms metabolize, some old microorganisms die, resulting in the production of excess sludge.
