The characteristic of the job of operating a raw water treatment system from sources like lakes, rivers, or wells to remove impurities, bacteria, and unwanted chemical compounds requires high levels of thoroughness and expertise. This job involves a series of complex steps and advanced technologies.

First, raw water is collected from the source and fed into the treatment system. Next, basic treatment processes like mechanical filtration are performed to remove large impurities, such as sediment from lakes or rivers. Then, the water goes through chemical and biological treatment stages to eliminate bacteria and harmful chemical compounds. This work requires close monitoring to ensure the treatment processes are effective and safe.

Operating specialists must have in-depth knowledge of water treatment technology, problem-solving skills, and a keen sense for detecting and resolving incidents that may arise during operation. At the same time, they also need to comply with safety and environmental regulations to ensure that the water treatment process does not harm the environment or human health.

2. Types of Accidents During the Process of Operating a Raw Water Treatment System from Lakes, Rivers, or Wells to Remove Impurities, Bacteria, and Unwanted Chemical Compounds

During the operation of a raw water treatment system from sources such as lakes, rivers, or wells, many notable types of accidents can occur. One of the common types of accidents is water leaks or spills, which can result from malfunctions or improper maintenance of system components like pipes, tanks, or water supply valves.

Water leaks not only cause water loss but can also lead to environmental pollution or risks to public health. Another type of accident can be an incident during the chemical treatment process, leading to incorrect dosage or causing unwanted reactions. In addition, technical problems such as machinery failure, power outages, or incidents in the control and monitoring process can also occur, causing interruptions in the water treatment process.

To deal with these accidents, operators need to be thoroughly trained in safety and emergency procedures, and the system needs to be designed with safety measures and risk controls to minimize the risk of accidents and limit adverse impacts on the environment and the community.

First, the rescue department should be notified immediately, and first aid should be provided immediately if necessary.

Next, the situation must be controlled to prevent the accident from spreading and to minimize damage. This may include cutting off the power supply or providing fire prevention and fighting measures if there is a risk of fire. At the same time, other employees should be notified and instructed to leave the hazardous area.

After that, an investigation into the cause of the accident should be conducted and preventive measures should be identified to avoid recurrence in the future. This may include reviewing procedures and equipment, as well as providing additional training for employees.
