Řízení biologické části ČOV Vsetín po III. intenzifikaci

Abstract

The present work describes the biological control of Vsetinske waste-treatment plant after the third intensification by intensifying the management of oscillating dissolved oxygen concentration in the aeration tank and using an ion-selective probes. The theoretical part describes the general objectives and methods of treatment intensification focusing on intensifying the removal of nutrients and may be used for various technological processes. A description of each activation systems for nutrient removal. There is also included and discussed the relevant Water CR and EU legislation. In the practical section comments on the current status and type of mechanical-biological treatment of waste water treatment plant Vsetin line with a detailed description of the latest technology, intensification and optimization of operation. Attention is paid to the modular probes control the cleaning process. The final section is paired with a test based on the results of comparative measurements verified the reliability of the control probe. Furthermore, the thesis evaluates the effectiveness of treatment in individual quality indicators, including an effect on the operation of the plant affecting water quality in the river Vsetínská Becva. Separate part is given power consumption. The conclusion is an evaluation of the benefits management process through a new probe technology in wastewater treatment.
