Abstract: For guiding the plant design, a sewage treatment plant model at Fujian is developed based on MANTIS model of GPS-X software. By simulating the treatment effect of different temperatures, it was found that the modified Bardenpho process has better nitrogen removal performance. Then the model was used to optimize the two suggested configurations of the modified Bardenpho process to achieve the IV class surface water quality standard in the plant effluent for both nitrogen and phosphorus removal.
Key words: GPS-X; upgrading and reconstruction; nitrogen and phosphorus removal; sewage treatment plant

隨著我國《水污染防治行動計劃》的頒布,污水處理廠的排放標(biāo)準(zhǔn)要求提升,其面臨著提標(biāo)的問題。對于高排放標(biāo)準(zhǔn)的污水處理廠,采用傳統(tǒng)簡單計算方法難以滿足設(shè)計要求[1; 2]。GPS-X軟件是污水處理廠的規(guī)劃設(shè)計、提標(biāo)改造及運行管理中的有效模擬仿真工具[3-6]。為指導(dǎo)污水處理廠提標(biāo)設(shè)計,本文應(yīng)用嵌入MANTIS模型的GPS-X軟件,以福建某污水處理廠為提標(biāo)改造對象,通過模擬分析,擬定提標(biāo)工藝方案,并在此基礎(chǔ)上進(jìn)行工藝優(yōu)化模擬,提出可行的提標(biāo)工藝,為基于數(shù)學(xué)模型的污水處理廠工藝優(yōu)化設(shè)計提供借鑒。
