Key precautions for using domestic wastewater treatment equipment that should be kept in mind
Release date:
2025-02-17
The treatment efficiency of domestic wastewater treatment equipment is very high. These integrated systems typically employ the biofilm process as their core technology. Compared with the activated sludge process, this method requires a smaller footprint, making it well-suited for constrained spaces; it also boasts greater loading capacity, delivers consistently stable effluent quality, generates less excess sludge, and entails relatively lower operational costs. In underground integrated wastewater treatment units, the biological treatment tanks are equipped with premium packing materials that feature light weight, high strength, stable chemical and physical properties, large surface area, and strong biofilm adhesion—factors that collectively enhance the efficiency of biofilm-based treatment.
When operating domestic wastewater treatment equipment, the daily safety operating procedures include:
1. In the event of a sudden power outage in the pump house or a major equipment failure, immediate measures must be taken to address the situation, and the relevant department of the wastewater treatment plant must be notified promptly. Under no circumstances shall power be restored or equipment repaired without proper authorization.
2. When cleaning the pump house sump, special attention must be paid to preventing poisoning. A detailed operating procedure should be prepared in advance, a confined-space entry permit issued, and compliance with the relevant safety regulations ensured.
3. Maintenance and repair personnel shall hand over the equipment to the operating staff after the pump has been started and is running stably, and may leave only upon confirming that everything is in order.
4. Frequent starting of the pump is strictly prohibited; the number of starts per hour shall not exceed three.
5. During pump operation, the pump must be stopped immediately if any of the following conditions occur: - A sudden abnormality or interruption in the control signal. - The appearance of unusual noises or vibrations. - An abnormally high temperature in the oil‑filled bearing chamber. - Abnormally high or low readings on the pressure gauge or ammeter. - Significant leakage from pipelines or valves within the machine room. - A serious malfunction of the motor.
These safety operating procedures are designed to ensure the safe operation of equipment and the safety of operators.
