DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

Recent year, environmental issue has been attened. The wastewater treatment of industrial park was the most important role for sustainable development. However, the performance information of dissolved organics processing were few in the industrial wastewater treatment plants. The data of dissolved organics removal was limited. Therefore, this research aimed to investigate the performance of wastewater treatment plant, the characteristics of dissolved organic removal and the kinetic characteristics of biological unit, based on wastewater treatment plant of Chuansing industrial park. The results can be used to improve the overall efficiency. 
Evaluating the wastewater treatment plant of Chuansing industrial park, the results show that :
(1) T-COD removal efficiency. The biological treatment unit was the highest (61.3%). The pretreatment processing unit was intermediate (31.3%), the chemical processing unit was the lowest (23.1%). (2) D-COD removal efficiency. The biological treatment unit was the highest (58.9%).The chemical processing unit was intermediate (27.7%), the pretreatment unit was the lowest (27.2%). (3) The suspended solids removal efficiency. The chemical processing unit was the highest (61.3%). The pretreatment unit was intermediate (49.3%), the biological treatment unit was the lowest (44.0%).Thus the biological treatment unit was the most important unit in the wastewater treatment plants.
Using the linear regression methods, the analyzed ratio of organics removal amount per SS removal amount as follow:
(1) When pretreatment processing unit remove 1 g SS, 1.87 g T-COD or 1.26 g D-COD was removed simultaneously.(2) When biological treatment unit remove 1 g SS, 5.42 g T-COD or 4.34 g D-COD was removed simultaneously. (3) When chemical processing unit remove 1 g SS, 1.07 g T-COD or 1.08 g D-COD was removed simultaneously. The characteristics of biological treatment was analysis using the moving average approach for 1-day,3-days,5-days,7-days. The results showed that the T-COD, D-COD with F/M (food to microorganism ratio) have good linear relationship. The 7-days moving average approach was the most stable method. Moreover, the D-COD and F/M showing the best linear relationship. This study could be reference for improving the operation of wastewater treatment plant.
