海水养殖尾水固废厢式压滤机分离性能仿真与参数优化
Numerical simulation and parameter optimization of the separation performance of a chamber filter press for marine aquaculture effluent solid waste
摘要
Abstract
To address the inefficient dewatering of solid waste in seawater aquaculture effluent(characterized by high moisture,viscosity,and fine particles),a chamber filter press was designed based on the slurry's measured physicochemical properties.A multi-chamber CFD model was established in FLUENT to simulate the filtration process.Operational parameters were optimized using a Box-Behnken response surface methodology targeting filter cake moisture content.The optimal combination was 0.85 MPa feed pressure,0.15 medium porosity,and 20%feed concentration,giving a predicted moisture content of 46.65%.Prototype tests yielded an average cake moisture content of 51.46%,with the filtrate containing 14.3 mg/L suspended solids at pH 7.55,meeting discharge standards.The study demonstrates that the chamber filter press,optimized through integrated CFD simulation and response surface methodology,achieves effective solid-liquid separation,providing a viable solution for the reduction and resource recovery of aquaculture solid waste.关键词
