精准加药系统在土工管袋固化清淤泥浆工程中的应用
Application of precision dosing system in geotextile bag solidification and dredging mud engineering
摘要
Abstract
In order to improve the reliability of the solidification and dredging mud technology for geotextile bags,a precise dosing system has been developed for mud solidification and applied to the G Lake dredging project in Jiangsu Province.The results showed that when the mud concentration was between 10%and 15%,the optimal PAC/dry mud ratio was 0.2%,and the PAM/dry mud ratio was 0.6‰.The precise dosing system detects the mud flow rate and concentration in real-time,calculates the required dosage,and instructs the dosing metering pump to accurately add the required dosage.The error between the actual dosage and the calculated dosage is about±5%.The average values of effluent turbidity,total nitrogen,total phosphorus,ammonia nitrogen,and permanganate index are 26.8 NTU,6.29 mg/L,0.19 mg/L,1.02 mg/L and 5.04 mg/L,respectively;The moisture content of the solidified mud inside the geotextile bag rapidly decreased to 70%,decreased to 60%after two weeks,and decreased to 50%after five weeks.关键词
