摘要
市政污水处理厂进水总氮逐步升高,传统的设计计算并未引入进水氨氮或硝化负荷参数,过高的进水总氮可能影响硝化反应.因此,在设计中需校核硝化负荷.通过阐述生物硝化的反应原理、硝化反应的主要影响因素、国内外关于硝化负荷的参数描述、国内部分已建污水厂的硝化负荷参数值,推测硝化负荷参数范围.
Abstract
Because the total nitrogen in influent of municipal wastewater treatment plants is increasing,the influent ammonia nitrogen and nitrification loading rate parameters are not considered in the conventional designs,high influent total nitrogen may affect the nitrification,so it is necessary to check the nitrification loading rate in the designs.This paper expounds the principle of biological nitrification,the main factors affecting nitrification,and some parameters of nitrification loading rate at home and abroad,and the nitrification loading rate parameters of some built wastewater treatment plants in China,and then,makes recommendations on the parameter range of nitrification loading rate.
