Abstract

The main purpose of the article is to develop a multifactorial model for rapid assessment of the efficiency of biological wastewater treatment reactors. A mathematical model of the process of biological wastewater treatment has been developed based on: changes in the concentration of organic contaminants in the bioreactor over time, taking into account the uneven flow of wastewater to the treatment plant, the process of substrate entering the bioreactor (different amounts may enter at different times). The software implementation of the proposed algorithm for solving the corresponding model problem in Python is carried out. The results of computer experiments on the study of the efficiency of wastewater treatment in biological treatment reactors for different operating conditions of facilities are presented. In particular, such processes were considered with taking into account the unevenness of the load, because the maximum cleaning loads are in the morning and in the evening. The task was solved to simulate a real situation and show how cleaning takes place at the maximum load at a certain time of the day. The results obtained will be useful for calculations in the design of biological treatment facilities or in the reconstruction of existing bioreactors for their prospective operation under new operating conditions.

处理系统负荷不均衡条件下的废水生物处理工艺研究

文章的主要目的是开发一个多因素模型，用于快速评估生物废水处理反应器的效率。建立废水生物处理过程数学模型的依据是：生物反应器中有机污染物浓度随时间的变化，同时考虑到废水流向处理厂的不均匀性、基质进入生物反应器的过程（不同时间进入的数量可能不同）。为解决相应的模型问题，在 Python 中对所提出的算法进行了软件实现。介绍了针对不同设施运行条件下生物处理反应器废水处理效率的计算机实验研究结果。特别是，考虑到负荷的不均匀性，因为最大清洁负荷出现在早晨和傍晚。这项任务的目的是模拟实际情况，并展示在一天中某个时间段的最大负荷下是如何进行清洁的。所获得的结果将有助于生物处理设施的设计计算或现有生物反应器的重建，以便在新的运行条件下运行。
