Overview

The principle of integrated domestic sewage treatment equipment: The removal of organic pollutants and ammonia nitrogen mainly depends on the AO biological treatment process in the equipment. The working principle is that due to the high concentration of organic matter in sewage, microorganisms are in a state of hypoxia. At this time, microorganisms are facultative microorganisms. Therefore, the * tank not only has a certain organic matter removal function, but also reduces the organic load of the subsequent aerobic tank. The organic matter concentration decreases, but there is still a certain amount of organic matter and high NH3-N present.

Overview of integrated domestic sewage treatment equipment:
Integrated domestic sewage treatment equipment is a device used to treat sewage in daily life. The application of room temperature anaerobic fermentation technology in small-scale domestic sewage purification biogas digesters, based on the principle of 'multi-stage self flow, step-by-step degradation', establishes a new device of stage I anaerobic fermentation and stage II facultative digestion filtration.
It consists of processes such as anaerobic fermentation, facultative digestion and filtration, wastewater reflux, and packing.
The concentration of rural farmers' residential areas is lower than that of cities, and the intensity of domestic sewage production is lower than that of cities. The financial resources of villages and towns are weak, and farmers have low incomes. Therefore, it is encouraged to adopt diversified domestic sewage treatment technologies that are economical, simple, effective, and combined with local agricultural production as much as possible to achieve harmless treatment and resource utilization of sewage. According to the process, it can be divided into biological contact oxidation method, SBR, A/O and A2/O.
The principle of commonly used A/O treatment technology is that microorganisms in anoxic tanks reduce nitrate nitrogen and nitrite nitrogen in wastewater to gaseous nitrogen and release it, while decomposing difficult to degrade large molecule organic matter into small molecule easily degradable substances, which have the functions of denitrification, hydrolysis, and degradation of some organic matter; In the aerobic tank, most of the organic matter is treated by microorganisms and enters the secondary sedimentation tank for sludge water separation. After disinfection, it is discharged.
The A/O process degrades organic matter while denitrification, greatly reducing oxygen demand, and is an energy-saving biological treatment technology. In order to maintain a high nitrification rate, the reaction residence time is longer than that of ordinary activated sludge process, the sludge settling performance is good, the sludge growth rate is low, the remaining sludge amount is small, and the settling performance is good.
