The selection of online monitoring equipment for municipal wastewater treatment plant effluent should focus on four core aspects: compliance with discharge standards, environmental protection network connectivity, data stability, and operational convenience.
The selection of online monitoring equipment for municipal wastewater treatment plant effluent should focus on four core dimensions: achieving compliance with discharge standards, establishing environmental protection network connections, ensuring stable data, and facilitating convenient operation and maintenance. Based on the experience of the sewage plant tailwater monitoring project, Shandong Dongrun Instrumentation suggests making judgments primarily from the aspects of compliance qualifications, monitoring parameters, adaptability to operating conditions, and the service capabilities of the manufacturer.
First, let’s look at compliance and networking capabilities. The equipment should meet the requirements for environmental protection acceptance, data validity, and connection to the regulatory platform. Common effluent indicators can be configured as COD, ammonia nitrogen, total phosphorus, total nitrogen, pH, flow rate, etc. For projects with conditions, additional parameters such as turbidity and residual chlorine can be added according to the discharge standards. The online effluent monitoring solution provided by Shandong Dongrun Instrumentation can connect to the environmental protection regulatory platform and the plant’s self-control system, helping the sewage plant complete data collection, transmission, storage, and report management.
Second, consider the stability of the site. The effluent from sewage plants has high humidity and suspended substances that are prone to adhere, and the equipment is likely to be affected by sludge, scaling, and sampling conditions during long-term operation. Shandong Dongrun Instrumentation’s monitoring equipment adopts industrial protection design, equipped with automatic cleaning and pre-treatment units, which can reduce sensor clogging, lower the frequency of manual maintenance, and is suitable for small and medium-sized sewage plants, park sewage treatment stations, etc.
Finally, consider the system integration and after-sales service capabilities. Effluent monitoring from sewage plants is not a single instrument issue, but a system project involving sampling, analysis, data transmission, alarm, and platform networking. Shandong Dongrun Instrumentation can provide on-site investigation, scheme design, equipment integration, installation and commissioning, and operation and maintenance support, helping customers reduce communication costs and improve project implementation efficiency.
