Ginger is a common seasoning and medicinal herb. In the production and processing process, especially during soaking and cleaning, a large amount of cleaning water is consumed, and a large amount of sewage is generated. These sewage not only contains sediment, but also contains a large amount of organic substances such as gingerol, ginger peel, ginger residue, as well as inorganic substances such as ammonia nitrogen, total phosphorus, and total nitrogen. The content and properties of these substances vary, requiring different treatment methods. Our company’s ginger washing and processing wastewater treatment equipment can professionally treat ginger washing wastewater, and we have rich experience in sewage treatment in this industry.
Process Introduction of Wastewater Treatment Equipment
The Wastewater Treatment Equipment works by using the buoyancy of bubbles to separate substances such as solid particles or oils suspended in water from the water.
It can be divided into three steps: bubble generation, bubble attachment, and bubble lifting.
The vertical flow air flotation machine injects gas into water through compressed air, forming a large number of bubbles. These bubbles rise in water and use the buoyancy of the bubbles to quickly lift and separate the residue, oil, soil particles, and other impurities suspended in the water. These bubble clusters rise faster in water and bring solid particles or oil and other substances suspended in the water to the surface, forming scum.
The formed scum is removed by equipment such as scrapers or pumps. The cleaned water enters the vertical flow air flotation machine again for treatment and recycling.
Advantages of Equipment for Ginger Cleaning and Processing
Wastewater Treatment Equipment
1. The system adopts an integrated combination method, which increases the water yield per unit area by 4-5 times and reduces the floor area by 70%.
2. The retention time of water in purification can be reduced by 80%, with convenient slag removal and low moisture content of the slag body. Its volume is only 1/4 of that of the sedimentation tank.
3. The dosage of coagulant can be reduced by 30%, and can be started or stopped according to industrial production conditions, making management convenient.
4. High degree of automation, easy operation, low energy consumption, convenient installation and transportation, and simple management.
5. High gas dissolution efficiency, stable treatment effect, and adjustable gas dissolution pressure and gas water reflux ratio as needed.
6. According to different water quality and process requirements, single or dual gas dissolution devices can be provided.
7.Use an efficient release device to improve the utilization efficiency of dissolved water while ensuring the stability of air flotation equipment operation.
Daily Maintenance of Wastewater Treatment Equipment
1. The pressure gauge reading on the gas tank should not exceed 0.6MPa.
2. Clean water pumps, air compressors, and foam scrapers should be lubricated regularly. Generally, air compressors should be lubricated once every two months and replaced once every six months.
3. The air flotation tank should be cleaned regularly based on the amount of sediment.
4. The sewage entering the air flotation machine must be dosed, otherwise the effect is not ideal.
5. Regularly check whether the safety valve on the gas tank is safe and stable.
