Description

Technical Field

[0001] The invention relates to the technical field of environmental engineering, and in particular to an oily wastewater treatment monitoring system. Background Art

[0002] Oily wastewater is a type of wastewater containing oil and fat pollutants, mainly from industries such as oil extraction, processing and food processing. The oil in this type of wastewater mainly exists in three forms: floating oil, emulsified oil and dissolved oil. Floating oil particles are large and relatively easy to separate; emulsified oil is difficult to separate due to its small particle size; and dissolved oil is dispersed in the water in a molecular state.

[0003] The methods for treating oily wastewater mainly include physical methods, chemical methods and biological methods. Physical methods mainly include oil separation and filtration; chemical methods include flocculation and flotation; biological methods use microorganisms to degrade organic matter. These methods can be used alone or in combination to achieve the best treatment effect.

[0004] Oily wastewater is very harmful to the environment. It will affect the growth and reproduction of animals and plants, destroy the ecological balance of water bodies, and even affect human health. Therefore, the reasonable and effective treatment of oily wastewater is crucial to protecting the environment and saving water resources. For this reason, the oily wastewater treatment monitoring system came into being. This is an automated system for real-time monitoring and control of the oily wastewater treatment process. This system can effectively reduce the impact of oily wastewater on the environment, improve treatment efficiency, and reduce treatment costs.

[0005] However, the current monitoring system for oily wastewater treatment also has some shortcomings, mainly reflected in the problems and challenges that may arise during the treatment process. For example, in order to maintain the pressure difference between the inlet and outlet, the monitoring system requires high cost operation, including precise control requirements for discharge and overall operating expenses. In addition, certain treatment methods, such as coarse granulation, may encounter the problem of easy clogging of the filler, requiring regular maintenance and cleaning to ensure treatment efficiency. Therefore, although the monitoring system for oily wastewater treatment plays an important role in environmental protection, it still needs to be continuously optimized and improved to solve these problems and challenges.

[0045] Beneficial effects:

[0046] 1. The present invention has the advantages of forming an efficient monitoring and control system through the control module, data processing and analysis module, and alarm and response module in the wastewater treatment monitoring system: Data processing and analysis module: real-time acquisition of wastewater data before and after treatment through instrument data sets and chemical online parameter data sets. The wastewater data includes the density and flow rate indicators of the wastewater, which provides a basis for subsequent calculation and analysis; Control module: This module receives data from the data processing and analysis module, and calculates the Reynolds number, pressure drop and mass transfer coefficient before and after wastewater treatment. The obtained parameters are very important for understanding the characteristics of fluid flow, optimizing the treatment process, and predicting and Diagnosing potential problems is crucial. The parameter difference and excess values ​​before and after the wastewater are used to determine whether there is a blockage and to clear it in time. Alarm and response module: When the parameter difference and excess values ​​before and after the wastewater are calculated in the control module, the alarm and response module will immediately trigger an alarm and trigger the control system to adjust the parameters to the normal range. This ensures that problems can be discovered in time when they occur, thereby reducing potential risks and losses. Combining the functions of the above modules, the wastewater treatment monitoring system can realize real-time monitoring and intelligent control of the entire treatment process, thereby achieving the beneficial effects of improving treatment efficiency and increasing safety, and ensuring environmental compliance.

[0047] 2. In the wastewater treatment monitoring system of the present invention, the pressure difference between the inlet and outlet can be monitored and controlled in real time by arranging the pressure difference sensors at various locations in the pipeline. When the system detects that the pressure difference in the pipeline exceeds the preset range, the prompt unit will immediately notify the alarm unit to sound an alarm. This early warning mechanism triggers the automatic control process of the pressure difference sensor, in which the pressure difference sensor sends a signal to the automatic valve, prompting it to adjust the opening to reduce the flow rate, thereby reducing the pressure difference in the pipeline. In this way, the system can continuously monitor and maintain the appropriate pressure difference between the inlet and outlet of the pipeline. This refined pressure difference control and monitoring system can not only effectively reduce operating costs, but also ensure accurate control of the drainage process, meet strict process requirements, and enable the wastewater treatment monitoring system to achieve the beneficial effect of reducing overall operating costs, while significantly improving the efficiency and reliability of the wastewater treatment process.
