“…(1) "Push" means that the server sends messages to each client, indicating that there is updated data. One way is to use the Socket port of the server to monitor and notify the client when there is data update [15].

In order to reduce the failure wear of rotating machinery, the subsequent economic loss and casualties, the remote vibration monitoring and fault diagnosis technology of rotating machinery based on B/S (browser/server) mode is studied. Firstly, the characteristics and structure of B/S mode, the remote vibration monitoring and fault diagnosis system of rotating machinery are analyzed and discussed. And then the system structure, flow chart, server and client design and implementation method are displayed. Subsequently, the overall scheme of rotating machinery fault diagnosis system based on B/S structure is designed. Furthermore, based on the idea of modularization, the scheme design of each module of the system is carried out, including network data acquisition and simulation experiment. Finally, the data and related information in the process of fault diagnosis are stored by analyzing the performance of database server, map refresh display and rotor phase. The remote monitoring system based on B/S can objectively reflect the vibration signal of rotating machinery, obtain the industrial field data in time, analyze the operation status of the equipment, find and correct the unreasonable elements in the design, and also show new design requirements and develop new products according to the actual needs of the site. It is helpful for on-site monitoring personnel to carry out routine monitoring and diagnosis of the equipment, saving about half of the human and material resources, and the results of remote monitoring are relatively accurate, which can diagnose the fault in time. Remote monitoring and fault diagnosis provide the first-hand information from the scene for scientific research institutes, and combine scientific research and production practice more closely. As a whole, large-scale rotating machinery is the key equipment in the production unit of enterprises. It is important to provide remote monitoring and fault diagnosis for enterprises. The achievements of remote monitoring and fault diagnosis system greatly improve the production efficiency.

A critical analysis of literature data on wastewater treatment from pharmaceuticals was carried out. It was shown that many different methods have been proposed for the treatment of wastewaters containing drugs, pharmaceuticals and veterinary medicines; all these methods can be classified as destructive and non-destructive ones. The traditional methods of wastewater treatment include the following: biological treatment, filtration and coagulation/flocculation/sedimentation processes, they being the most common in sewage purification. Some up-to-date and advanced methods (advanced oxidation processes, electrochemical treatment, etc.) are also known. The used methods of wastewater treatment from pharmaceuticals can be conventionally divided into several following groups: (i) chemical treatment with the addition of hydrogen peroxide and/or other oxidants, such as ozone and sodium hypochlorite, together with catalysts to the system; (ii) photocatalytic methods; and (iii) electrocatalytic methods. It was noted that peroxene-based systems are especially promising for practical application; they imply the use of hydroxyl radical as an effective oxidant that is formed from the primary oxidant by its catalytic decomposition. The so-called conditionally reagent-free methods are considered as an alternative to chemical treatment methods, they include electrocatalytic and photochemical techniques, where oxygen-containing radicals (i.e. oxidizing agents) are formed under the action of electric current or UV radiation on the proper catalysts. An additional advantage of electrochemical methods is the possibility of direct electrochemical destruction of organic substances. The main disadvantages of such methods as well as other heterogeneous catalytic systems are relatively high sensitivity to the composition of a catalyst and too low process rate due to decelerated delivery of pollutants to the interfacial boundary where the reaction occurs.
