Intelligent domestic sewage treatment equipment

Operating principle

The intelligent domestic sewage treatment equipment adopts the physical pretreatment+improved biochemical degradation+intelligent adaptive control+online monitoring and disinfection closed-loop treatment process, and realizes the automatic, intelligent and fine operation of sewage treatment by combining the Internet of Things technology.

The domestic sewage flows into the equipment pretreatment grid regulation area by gravity through the pipe network to automatically intercept hair and suspended debris, balance water quality and quantity, and buffer the fluctuation of sewage concentration in peak period; Homogeneous sewage enters the anaerobic anoxic zone, the anaerobic bacteria fully decompose the macromolecular organics, complete the denitrification pretreatment, and improve the biodegradability of the water body; Then, it enters the intelligent aerobic biochemical zone, and the system automatically regulates the aeration air volume and operation load according to the real-time water quality and inflow volume, so as to effectively adsorb and oxidize the organic pollutants, ammonia nitrogen and total phosphorus by the biofiller flora; The biochemical mixed liquid flows into the inclined tube sedimentation area to complete the mud-water separation, the sludge returns to the biochemical system automatically, and the remaining sludge is cleaned and transported regularly; The supernatant enters the intelligent disinfection unit and automatically dosed or started the disinfection module as required to kill Escherichia coli and microorganism. The online water quality monitoring module is configured throughout the process to collect data in real time, automatically pre-warn abnormal conditions and automatically correct parameters, so as to ensure the continuous stability of effluent indicators and realize all-weather intelligent standard operation.

Product advantages

H6>Intelligent cloud control, truly unattended

Different from the traditional semi-automatic equipment, it is equipped with a full set of intelligent system of Internet of Things, which can automatically regulate the working conditions in the whole process, upload real-time data, and give early warning of abnormal failures. Without the need of special personnel on site, it can remotely master the overall operation of the equipment, greatly free manual operation and maintenance, and adapt to the unified management of the contiguous decentralized sewage stations.

H6>Self-adaptive frequency conversion operation, significant energy conservation and consumption reduction

The system can automatically adjust the operation load of aeration and pump body according to the water inflow and pollutant concentration, eliminate the invalid energy consumption of traditional equipment under constant high load, accurately match the treatment conditions, lower energy consumption under the same treatment capacity, and highlight the economic advantages of long-term operation.

H6>The data is saved in the whole process, easy to deal with environmental protection acceptance

The equipment automatically records daily operation data, water quality parameters and equipment startup and shutdown records, and can automatically generate operation and maintenance reports. The data can be traced, exported and uploaded, perfectly adapting to the requirements of environmental protection normalization check, project acceptance and intelligent water affairs transformation.

H6>Stable process upgrading, controllable effluent index

The improved AAO biological treatment process is adopted, and the sludge membrane collaborative purification has excellent nitrogen and phosphorus removal effect, strong water quality and water impact resistance, which can adapt to the daily concentration fluctuation of domestic sewage, intelligently correct the operating parameters in the whole process, and make the effluent stable and meet the standard without fluctuation.

H6>closed, low noise and environmental protection, suitable for residential scenes

The fully enclosed box structure is designed with low operation noise, no odor spillover and no secondary pollution. The surface can be covered with soil for greening, and the appearance is clean and beautiful. It can be installed nearby villages, homestays, communities and other residential areas, without affecting the daily living environment.

H6>Modular customization for a wide range of scenarios
