Problems solved by technology

[0008] Due to the complexity of these USAB or EGSB processes and the excessively large number of parameters to consider, there has not been an application of soft sensors for USAB or EGSB processes to predict outflow parameters such as TOC

Embodiment Construction

[0031] In the specification, it will be appreciated that the term "effluent" refers to the treated wastewater from the anaerobic / EGSB reactor. The treated wastewater may or may not be of discharge quality, i.e. the treated wastewater from the anaerobic / EGSB reactor may require further treatment to achieve adequate quality.

[0032] According to an embodiment of the invention there is a method 200 for predicting parameters of a wastewater treatment process (WWTP). In particular, the method is applicable to (but not limited to) EGSB plants / reactors, and the parameter to be predicted is total organic carbon (TOC) in the effluent of the EGSB reactor.

[0033] as shown and refer to figure 1 , a typical EGSB10 system and process includes an inflow regulation tank 20 and an EGSB reactor 30 . In the EGSB reactor 30, the granulated microorganisms are contacted with the influent wastewater from the inflow conditioning tank 20 at a relatively high flow rate. The waste water is continu...

Abstract

The invention describes a method for predicting a parameter of wastewater treatment process. The method comprises the following steps: obtaining a data set comprising a plurality of process variables related to the parameter of the wastewater treatment process; obtaining a predetermined number of measurement values of the parameter to be predicted; preprocessing the obtained data set, wherein preprocessing steps comprises classifying the data set into input groups which comprise the data set and the measurement values of the parameters to be predicted; obtaining a synthesized output at each soft sensor; averaging the synthesized outputs of each soft sensor crossing the soft sensors; and setting the synthesized output after the averaging as a final prediction parameter.

Description

technical field [0001] The present invention relates to systems and methods for predicting parameters of wastewater treatment processes. In particular, the system and method are suitable for, but not limited to, the prediction of outflow parameters in expanded granular sludge bed (EGSB) processes and will be described hereinafter. Background technique [0002] Throughout this specification, unless the context requires otherwise, the word "comprise" or variations such as its singular or present participle forms will be understood to imply the inclusion of indicated integers or groups of integers but not the exclusion of any other integers or groups of integers. . [0003] Furthermore, throughout this specification, unless the context requires otherwise, variations of the word "comprise", such as its singular or present participle, will be understood to imply the inclusion of indicated integers or groups of integers, but not the exclusion of any other integers or integers.
