Method for simulating chemical phosphorus removal process

Abstract

The invention discloses a method for simulating the chemical phosphorus removal process. The method is used for conducting the quantitative description on the removal process of phosphorus in waste water. The method includes the steps of building a mathematic model of the phosphorus concentration, the phosphorous removal pharmaceutical dosage and the remaining phosphorus concentration of raw water, and giving an expression of the relationship between parameters under multiple phosphorus removal working conditions; embedding the mathematic model in a simulation platform of the wastewater treatment process, enabling a chemical phosphorus removal model to form an independent calculating module, and conducting quantitative calculation to obtain corresponding results such as the phosphorus removal amount in the chemical phosphorus removal process; inputting the parameters such as the inlet water flow, the amount and the type of fed phosphorous removal pharmaceutics and the like into the simulation platform, and obtaining corresponding forecasting results according to the parameter simulation. By means of the method, the quantitative description on the chemical phosphorus removal process can be achieved, the corresponding phosphorus removal results generated by the amount and the type of the fed phosphorous removal pharmaceutics on the chemical phosphorus removal process can be visually displayed, and meanwhile the positive assisting and pushing effects on process control, related technology simulation and modeling of the chemical phosphorus removal can be achieved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for simulating the process of chemical phosphorus removal by establishing a mathematical model for chemical phosphorus removal and embedding the model into sewage treatment simulation software. Background technique [0002] The eutrophication of water bodies is one of the most challenging water environment problems facing human society. In recent years, with the intensification of urbanization and the development of industry and agriculture, more and more untreated sewage has been discharged into rivers, lakes and seas. Among them, nitrogen and phosphorus, two plant nutrients, are the cause of eutrophication in water bodies. The culprit is often causing ecological problems such as red tides and algae blooms, which seriously endanger the water environment and water safety. Therefore, the removal of nitrogen and phosphorus elements in sewage has become one of the...

Problems solved by technology

[0004] Single use of biological phosphorus removal or chemical phosphorus removal will have problems such as unsatisfactory treatment effect or high treatment cost due to excessive dosage of chemicals. Therefore, the ideal treatment process is the combination of the two, that is, the use of chemical methods Phosphorus, in order to obtain better water quality with a relatively small dosage
