AI Technical Summary

Technical Problem

The existing sewage treatment plants have too complicated detection methods for phosphorus removal agents, resulting in low quality inspection efficiency and inconsistent with production actual conditions.

Method used

A rapid quality inspection method is adopted to calculate the iron oxide content in the phosphorus removal agent as the main evaluation index through sampling, dilution, stirring, dropwise addition of sodium carbonate solution, filtration, washing, and roasting, and combine the phosphorus removal curve as an auxiliary quality inspection method.

Benefits of technology

The efficiency of phosphorus removal agent quality inspection is improved, making the detection more in line with the actual production, and can screen out phosphorus removal agents that meet production needs more quickly and effectively.

Abstract

The invention relates to the technical field of sewage treatment agent detection, in particular to a rapid quality inspection method for a phosphorus removal agent in a sewage treatment plant. According to the method, the content of iron oxide in the dephosphorization agent is used as a main evaluation index, and a dephosphorization curve of the dephosphorization agent for the dephosphorization effect of an actual water sample is used as an auxiliary evaluation index; the iron oxide content is used as a main evaluation index, so that unnecessary indexes such as basicity and the like required to be measured traditionally are avoided in the process, and the process is quicker; meanwhile, in cooperation with auxiliary evaluation indexes of a dephosphorization curve, indexes such as COD, alkalinity, hardness and pH can be comprehensively considered in the quality inspection process, and the method better fits production reality and is more efficient. The method is more suitable for actual production, the quality inspection process of the dephosphorization agent is quicker and more efficient, the agent better meeting the actual production can be screened out, and the method plays a positive role in improving the quality inspection efficiency and guaranteeing the dephosphorization effect.
