Solutions

Rainwater and sewage separation, a drainage system, refers to the separation of rainwater and sewage, and the discharge or subsequent treatment of sewage by pipes. Rainwater is directly discharged into the river through the rainwater pipes, and sewage is collected through the sewage pipes and sent to the sewage treatment plant ,so as to avoid sewage being directly discharged into the river and causing pollution. The collection and utilization of rainwater and the centralized management of discharge can reduce the impact on sewage treatment plants and ensure the treatment efficiency. The intelligent rainwater and sewage diversion system can control the discharge of sewage into the surface water environment and municipal rainwater pipes, and also control the discharge of surface water such as rivers, lakes into the sewage system.

I. System composition

In order to improve the information level of management work and establish a network management system, industrial-grade intelligent telemetry terminal M21F4 is used to help create a remote monitoring and management system for sewage diversion treatment based on 4G/5G network. Through various detectors, sewage treatment monitoring points will be detected using various sensors and special instruments to collect physical and chemical parameters related to sewage treatment, such as the operation status of sewage treatment equipment, industrial water discharge sewage flow, sewage PH value, relative turbidity of sewage, etc. Various data are transmitted from the communication port of the monitor to the remote monitoring center station. The monitoring center carries out data summarization, collation and comprehensive analysis; at the same time, the monitoring information is transmitted to the Environmental Protection Bureau, which supervises and manages the enterprises. The intelligent and smart rainwater and sewage treatment remote monitoring system consists of four parts: monitoring center, communication network, front-end monitoring equipment and measuring equipment.

Front-end monitoring equipment: sewage monitoring terminal, valve/gate opening and closing control

Communication network: 2G/3G/4G/5G communication method is the main one, supplemented by SMS backup (Beidou satellite can be customized).

Monitoring center: cloud server, receiving and processing integration platform, etc.

Measurement equipment: rain sensor, water level meter, water quality sensor, camera or other instrument transmitter.

Fourth, the value of the system

Intelligent rain and sewage diversion online monitoring system is a comprehensive application system that fully relies on the wide coverage, high bandwidth and mobility of 3G/4G wireless network to provide data transmission, video monitoring, alarm and other multi-functional features. At the same time, it is used to seamlessly interface with the widely used automation control system in industry to realize the automatic integration control of gates/valves. The data acquisition terminal is applied to various online monitoring systems in water conservancy/environmental protection/industrial control industries, and has been recognized and favored by customers in terms of stability, security, transmission fluency, and image clarity, and has been applied in many industries. Rainwater and sewage treatment has played an important role in reducing the amount of sewage discharge, improving the water environment and promoting the effective use of water resources, and is an important measure to alleviate the scarcity of water resources and improve the scientific and informational level of environmental management.
