Application of Jet Aeration in Sugarcane Wastewater Treatment
Application of Jet Aeration in Sugarcane Wastewater Treatment
I. Basic Project Overview
Sucrose wastewater primarily originates from wastewater generated during ethanol production, Poor biodegradability, high viscosity, Poor humus formation, COD concentrations as high as 100,000–120,000 mg/L, Fully treated using biological
methods, Complex manufacturing processes, high costs, and significant investment requirements.
Based on the characteristics of this wastewater, Employing biological fertilizer technology, Utilizing facultative anaerobic bacteria to ferment and oxidize alcohol waste distillate into mature humic acid.
Due to the high viscosity of the alcohol wastewater produced from sucrose, Microporous aeration discs or tubes are prone to clogging and produce uneven aeration, Low oxygen utilization rate, insufficient oxygen supply capacity, Traditional
MTS jet aeration systems exhibit low oxygen utilization efficiency, Pipeline layout is complex, investment is high, and energy consumption is high.
To address the above issues, Yunnan Yingmao Sugar Industry Co., Ltd. procured GW jet aerators from Chengdu Greenwater Technology Co., Ltd. for oxygen supply and aeration in the anoxic tank.
III. Operational Processing Results
In the anoxic tanks with dimensions of 18×18×3m, 25×15×4.5m, 20×20×3m, 14×14×3m, and 15×15×4.5m respectively, 2 sets, 3 sets, 2 sets, 2 sets, and 2 sets of GW1200 jet aerators were installed.
The flow rates of the jet pumps for each pool are as follows:
1. Flow rate: 200 m3/h, Head: 18m, Installed power: 15 kW, Quantity: 2 units.
2. Flow rate: 300 m3/h, Head: 18m, Installed power: 22 kW, Quantity: 3 units.
3. Flow rate: 310 m3/h, Head: 22m, Installed power: 30 kW, Quantity: 2 units.
4. Flow rate: 150 m3/h, Head: 22m, Installed power: 15 kW, Quantity: 2 units.
5. Flow rate: 200 m3/h, Head: 18m, Installed power: 15 kW, Quantity: 2 units.
IV. Project-Related Diagrams
Following the client's original design, oxygen supply is achieved using the GW blower pressurized jet aeration method, In actual operation,No need to employ forced-air pressurized jet aeration, Simply adopt the GW jet self-priming
aeration method to achieve oxygenation. Since commissioning, the jet pump has demonstrated the following significant advantages:
1. Excellent oxygenation capacity, with effluent quality meeting liquid fertilizer requirements.
2. Simple installation and maintenance: The pump is mounted outside the tank, facilitating easy maintenance and repairs. This addresses the issues of traditional microporous aeration tubes, such as frequent clogging, low oxygen utilization
efficiency, insufficient oxygen supply capacity, complex maintenance procedures, and high repair costs.
3. GW jet aeration systems feature low noise levels, eliminate the need for blower systems, and consume significantly less energy than design specifications.
4. The jet nozzle and efficiency-enhancing nozzle maintain consistent performance over extended operation and require no maintenance, significantly reducing maintenance costs
