Application with Internet of things technology in the municipal industrial wastewater treatment based on membrane bioreactor process

Abstract

Anoxic–oxic process is also called anaerobic aerobic process and used widely with the membrane bioreactor (MBR) for wastewater treatment, particularly in China, thanks for their high efficiency, good-quality permeate and easy operation. However, because the content of the feed wastewater fluctuates in a large range and the operation condition of the system needs to be controlled accurately, it is very important to find an efficient way to constantly monitor the nodes of the system, and adjust the operation parameters, including the quantities used in the chemical treatment. Therefore, it is necessary to use Internet of things technology (IOT) sensing and control equipment to realize the dynamic monitoring of sewage treatment process parameters, so as to serve the drug delivery and equipment online control. This study introduces an application case based on IOT sensor control and supporting maintenance business. Through the practical application of this technology in an environmental protection sewage treatment enterprise in Wuxi, this study introduces a method of bringing the IOT into the MBR system of industrial wastewater treatment which can continuously and accurately monitoring the nodes of the system. Based on this study, an analysis and decision-making system based on real-time monitoring data can be realized to adjust operation parameters in time. In this method, the IOT is introduced into the MBR system of industrial wastewater treatment. The results show that with the support of IOT, the sewage treatment system runs stably and the treatment efficiency is significantly improved.

[Retracted] Intelligent Garden Planning and Design Based on Agricultural Internet of Things

“…Sending the development of these technologies to the planning and design of smart gardens provides new references and breakthrough directions, and promotes the development of agricultural industrialization. China National Nuclear Corporation is also a leading enterprise, but the development of leading enterprises must seek correct guidance from the government, and obtain support for policies and concessions in agricultural industrialization [16]. According to the principle of "supporting the best, supporting the big, supporting the strong," the government should make reasonable arrangements for overall planning.…”

Intelligent Measurement and Analysis of Sewage Treatment Parameters based on Fuzzy Neural Algorithm with ARM9 Core CPU

“…The neural network training algorithm process is characterized by both forward and reverse propagation. When the signal adopts the “input layer-implicit layer-output layer” process, it reflects the state of forward propagation [ 21 ]. When the hidden layer receives the signal and produces an error with the output signal, and the error exceeds a desired range.…”

Industry 4.0 Applications for Medical/Healthcare Services

“…Technologies such as IoT, blockchain, Cloud Computing, and AI have led to some fantastic improvements in healthcare. The role of Industry 4.0 in healthcare is extraordinary, as it has reduced time, costs, and led to the implementation of better solutions [76] IoT has gained a lot of attention, due to its deployment in different sectors, and can be beneficial in areas such as wastewater treatment [77,78], climate study, remote sensing [79][80][81][82], smart grid security, healthcare, and so on. In the healthcare sector, the "digital data foundation" consists of modern technologies, including IoT, which is also one of the fastest adopted technologies at present.…”
