Secondary biochemical sewage treatment equipment
In today's society, with the continuous development of industry, the discharge of sewage is also increasing. In order to protect the environment and reduce the waste of water resources, many enterprises have begun to use biochemical sewage treatment equipment to treat sewage. Among them, secondary biochemical sewage treatment equipment is a more common treatment equipment. This article will introduce in detail the characteristics and principles of secondary biochemical sewage treatment equipment, as well as how to use and maintain the equipment correctly.
Characteristics of primary and secondary biochemical sewage treatment equipment
Secondary biochemical sewage treatment equipment is an advanced sewage treatment equipment, which converts the organic matter in the sewage into harmless substances through the process of microbial degradation and chemical reaction, so as to achieve the purpose of purifying water quality. The device has the following features:
1.High treatment efficiency: The secondary biochemical sewage treatment equipment can effectively remove organic substances and harmful substances such as ammonia nitrogen in the sewage, and the treatment efficiency is high.
2.Adaptability: The equipment can adapt to different types of sewage, such as domestic sewage, industrial wastewater and medical wastewater.
3.Low operating cost: The secondary biochemical sewage treatment equipment has low operating cost, easy maintenance and long service life.
4.Environmental protection and energy saving: The equipment adopts biodegradation technology, which will not produce secondary pollution, and has the characteristics of energy saving and environmental protection.
Second, the principle of secondary biochemical sewage treatment equipment
The principle of secondary biochemical sewage treatment equipment mainly includes two processes: microbial degradation and chemical reaction. In the process of microbial degradation, microorganisms use the organic matter in the sewage for metabolism, converting the organic matter into harmless substances such as carbon dioxide and water. At the same time, microorganisms also consume oxygen, converting harmful substances such as ammonia nitrogen into harmless substances. During the chemical reaction, some organic substances in the wastewater will react with chemical agents to form precipitates or gases, which further purify the water quality.
3. Correct use and maintenance of secondary biochemical sewage treatment equipment
The following points need to be paid attention to in the use and maintenance of secondary biochemical sewage treatment equipment:
1.Equipment location: When choosing a location for equipment placement, you need to consider factors such as high terrain, dry environment, convenient transportation, and noise interference. At the same time, the surrounding environment of the equipment needs to be kept dry and well ventilated.
2.Equipment operation: Operators need to be professionally trained to master the operating procedures and precautions of the equipment. During use, it is necessary to regularly check the operating status of the equipment and whether the parameters are normal.
3.Maintenance: Regularly inspect, clean and maintain the equipment to ensure the normal operation and treatment effect of the equipment. At the same time, consumables such as chemicals and filter materials need to be replaced regularly to ensure the treatment effect of the equipment and the quality of the effluent.
4.Safety measures: During use and maintenance, it is necessary to pay attention to safety measures. For example, operators need to wear protective equipment, prohibit touching the inside of the equipment, etc. At the same time, it is necessary to develop an emergency plan to deal with the occurrence of unexpected situations.
In short, the secondary biochemical sewage treatment equipment is an advanced sewage treatment equipment, which has the characteristics of high efficiency, low cost, environmental protection and energy saving. In the process of use and maintenance, it is necessary to pay attention to the location, operation, maintenance and safety measures of the equipment to ensure the normal operation and treatment effect of the equipment.
