摘要

背景:为了控制污染,纺织废水处理在处理废水达到质量标准后再排入环境中发挥着重要作用。纺织业的废水如果没有得到妥善处理,就会含有有机和无机污染物,造成水污染、海洋生物损失以及土壤和空气污染等环境问题。本研究的目的是设计和模拟一个纺织污水处理厂。方法:采用STOAT软件对某污水处理厂的工艺和运行情况进行模拟研究。此外,STOAT的图形和静态数据分析模型能够有效地去除纺织行业中的多组分污染物。结果:设计模型前的一些污染物参数为悬浮固体(SS)(260 mg/L)、DS(3600 mg/L)、氨(65 mg/L)、生化需氧量(BOD)(430 mg/L)、硝酸盐(35 mg/L)和溶解氧(DO)(12 mg/L)。污水处理厂模型模拟结果的废水含有SS(3.3 mg/L)、氨(25 mg/L)、BOD(4 mg/L)、硝酸盐(61.3 mg/L),总悬浮物(TSS)、BOD和氨的去除率分别为99.75、99.1和61.33 mg/L。通过处理过程,氨被氧化,硝化作用而不是反硝化作用。结论:利用stoat建模软件,通过选择特定的参数,污水处理厂的设计对去除纺织废水中的污染物是非常有效的。

Performance improvement of textile wastewater treatment plant design by STOAT model simulation
Background: To control pollution, wastewater treatment from textile plays an important role in treating wastewater to meet quality standards before it is discharged into the environment. Without properly treated wastewater from the textile industry, it contains organic and inorganic pollutants that cause environmental problems such as water pollution, loss of marine life, and soil and air pollution. The aim of this study was to design and simulate a textile sewage treatment plant. Methods: This study was conducted by simulating the process and operation of a wastewater treatment plant using STOAT software. In addition, STOAT’s graphical and static data analysis models are efficient in removing multi-component pollutants from the textile industry. Results: Some pollutant parameters prior to the design model are suspended solids (SS) (260 mg/L), DS (3600 mg/L), ammonia (65 mg/L), biochemical oxygen demand (BOD) (430 mg/L), nitrate (35 mg/L), and dissolved Oxygen (DO) (12 mg/L). The wastewater of the simulation result of the sewage treatment plant model contained SS (3.3 mg/L), ammonia (25 mg/L), BOD (4 mg/L), nitrate (61.3 mg/L), and the removal percentage of total suspended solids (TSS), BOD, and Ammonia was 99.75, 99.1, 61.33 mg/L, respectively. Through the treatment process, Ammonia was oxidized and nitrification was processed rather than denitrification. Conclusion: Using the stoat modeling software, wastewater treatment plant design is very effective in removing contaminants from textile wastewater by selecting specific parameters.
