Description

Rapid detection system for activated sludge

Technical Field

The utility model relates to a sewage treatment technical field, concretely relates to active sludge's quick detecting system.

Background

At present, the urban and rural domestic sewage treatment process generally adopts an activated sludge method, which comprises the steps of culturing activated sludge, mixing the activated sludge with sewage, contacting and adsorbing the activated sludge in a suspension state, carrying out complex biological reaction, and then carrying out flocculation precipitation to remove pollutants such as COD, TP, TN, SS and the like dissolved in the sewage, so that the sewage reaches the discharge standard of urban sewage and then is discharged to the environment. Activated sludge plays a very important role in sewage treatment, so the sewage treatment is the maintenance and management of the activated sludge. During the operation of a sewage treatment plant, inflow water often encounters the condition of water quality fluctuation caused by unknown factors, such as pollutant concentration change, component change, temperature change, toxic substances and the like in sewage, which all have adverse effects on the operation of an activated sludge system and even collapse.

Therefore, the properties of the activated sludge must be grasped and controlled in time for the stable operation of the sewage treatment process. Because the active sludge has more complex components and consists of a great variety of microorganisms, micro-animals, inorganic substances, related secretions and the like, such as dehydrogenase, ATP and the like, the detection is more troublesome, the time is longer, and the cost is higher; in production, manual sampling, sludge sedimentation index detection and the like are mostly used for replacement, but the defects of small detection quantity, data lag, high personnel requirement, inconvenience for unmanned centralized management of rural sewage treatment and the like exist.

The informatization and unmanned sewage treatment process control puts higher requirements on activated sludge detection equipment in the process flow, and the equipment is required to be capable of automatically and quickly detecting the activated sludge, has rich information remote transmission and provides closed-loop parameters for automatic operation and control.

2. And a limited online instrument, a sludge concentration meter and a sludge interface instrument are installed, and are instantaneous values with lagged sludge character evolution, information is independent and not integrated, and application and analysis are difficult. At present, the suspension concentration at a certain point can be reflected instantly, and the integral sedimentation performance of the sludge, the granulation degree of the sludge and the like cannot be revealed.

3. The intelligent sewage treatment management system has high requirements on the aspects of accurate aeration and accurate reflux control, and at present, part of stations extract the concentration of dissolved oxygen and the concentration of suspended sludge in sewage by establishing a bioreactor model, help a control center to automatically correct aeration quantity, reflux quantity of digestive juice, reflux quantity of sludge, sludge discharge period and the like, and adjust sludge load and sludge concentration so as to achieve automatic process management. Due to the limitation of the sensing detection technology, the feedback of the biological reaction system fails, the model construction is difficult, the operation is unstable, and the popularization is not realized.
