With the development of aquaculture, the amount of sewage discharged from farms has become larger and larger, causing serious pollution to surface water and a deteriorating environmental quality. However, the water quality monitoring of pollution sources and sewage canals in various places is still at the manual monitoring stage, with low time coverage, lack of scientificity and representativeness of samples, and it is difficult to reflect the continuous changes in sewage discharge from farms and aquaculture. The country and various provinces and cities are paying more and more attention to the protection of the ecological environment and are constantly strengthening the governance of water resource pollution. However, due to the lack of environmental protection awareness and the drive of interests, there are many factors such as random sewage discharge and non-standard sewage discharge, which cause serious environmental pollution. Therefore, it is also necessary to increase investment in monitoring and supervision, and provide an effective, practical and advanced monitoring system and solution. It is extremely urgent to strengthen environmental monitoring. It is imperative to establish an online monitoring system for wastewater and sewage and improve water quality monitoring capabilities.
This system is a sewage monitoring system composed of sewage discharge monitoring points, monitoring center stations and management centers. The system can realize automatic sampling of industrial wastewater and sewage from aquaculture farms, online monitoring of flow and online monitoring of major pollution factors; real-time grasp of sewage discharge conditions and total pollutant discharge of enterprises and aquaculture farms, and automatic transmission of monitoring data; water quality parameters are automatically collected, processed, stored and transmitted via remote communication by monitoring points, and data are summarized, sorted and comprehensively analyzed by the computer control center of the monitoring center; monitoring information is transmitted to the Environmental Protection Bureau, and the management center supervises and manages enterprises.
1. Monitoring points for wastewater discharge from breeding farms
The farm sewage treatment monitoring point uses various sensors or special instruments to collect physical and chemical parameters related to sewage treatment, such as the operation status of sewage treatment equipment, industrial water inflow/total amount, sewage discharge flow/total amount, sewage pH value, relative turbidity of sewage, etc. Various data are transmitted from the communication port of the monitor to the DTU, which converts the data into TCP/IP packets and sends them to the monitoring center station data center server port with a fixed IP address or domain name set in the DTU.
2. Monitoring Center Station The computer system of the monitoring center station is mainly composed of data communication subsystem, data processing subsystem and reporting system, and its main functions include data communication, data processing, reporting statistics and analysis, etc. The data processing subsystem and reporting system are the main human-computer interaction interfaces, receiving information transmitted from monitoring points and monitoring information from other pollution sources; responsible for classification, screening and comprehensive analysis of monitoring information; completing statistics, calculation and processing of data, and automatically generating various reports; with storage, display, recording, printing, statistics and other functions, and can also send relevant query commands and control information to monitoring points.
3. Management Center
The management center is composed of relevant departments of the Environmental Protection Bureau and is the decision-making center of the system. It mainly analyzes and investigates the monitoring data obtained from the monitoring center station, makes management decisions in a timely manner, increases management efforts, and sets up a large-screen projection system to display the distribution of key pollution sources and monitoring results in the jurisdiction area. At the same time, the computer multimedia voice system can be used to demonstrate the environmental quality status.
Sewage data monitoring is widely used and directly related to ecological and environmental safety. Under the special background, the national policy is also vigorously promoted. Xiamen Caimao has been applied nationwide in the field of sewage treatment monitoring. In the context of the Internet of Things, Xiamen Caimao's solutions and products have been widely used in mobile POS terminals, finance, supply chain automation, intelligent transportation, industrial automation, smart buildings, smart homes, fire protection, public safety, environmental protection, meteorology, digital medical care, remote sensing survey, military, space exploration, agriculture, forestry, water, electricity, coal mining, petrochemical and other industries.
