In order to grasp the overall status of sulfur autotrophic denitrification related patents, and better carry out sulfur autotrophic denitrification related research and intellectual property protection, based on the SooPAT Chinese patent search engine and Baiteng.com platform, from the first patent application year to the search deadline was to analyze the number, legal status, technical field distribution, and patent value of the sulfur autotrophic denitrification patents filed in China. The results showed that the number of patents filed each year had increased rapidly since 2012. The number of patents filed in 2019 was 10 times the number of patent applications from 2001 to 2011, and the patents granted were mainly concentrated in the field of sewage (waste) water treatment, accounting for 83.64% of the total number of patents. The overall patent value was in the middle and lower level, and there were no high-value patents.

<p>Our data on the legal status of patent applications is from European Patent Office's (EPO) PATSTAT database which contains bibliographic and legal status firm-level patent data from leading industrialized and developing countries for the period 1995-2015. Sixteen different forms of legal statues are broadly classified and systematized into four broad categories. The first category entails the patent applications sent to EPO. This category is used to code firm-level observations based on whether the patent application has been submitted to EPO. The second category comprises the pooled firm-level observations for which the patent application has been approved and official validated. This category comprises the firms for which a valid patent has been approved in a given year. The third category comprises the firms whose patent application has been rejected by EPO on various ground which exceed the scope of this paper.

The development status and trend of the patents related to sewage treatment technology in Dalian, China in the past decade may affect the future environmental protection industry development. The status quo of patent applications related to wastewater treatment technology was analyzed from the perspectives of application volume, disclosure volume, application organization, type composition of invention and utility model patent products and legal status. The results indicated that the total number of filed patents were 894, and the number of issued patents were 914 in recent ten years, showing an increasing trend for sewage treatment technology in Dalian, China. However, there were distinct differences between the application agencies of invention patents and utility model patents. Most of the invention patents came from universities, with 264 in the top five, and most of the utility model patents came from enterprises, with 134 in the top five. Among the product types, the highest number of patent applications was water, wastewater, or sludge treatment technology, a total of 761. At this point, the two patent directions had the same trend. In the state of law, although the number of applications and disclosures was 470, which was more than 416 actually authorized, it was not difficult to find that sewage treatment industry in Dalian, China was in an increasingly developing stage and the patents actually obtained had higher quality assurance. In conclusion, this essay from the perspective of patent application made a simple explanation the future development of sewage treatment industry and the problems existing in the practical application of sewage treatment technology. Finally, from the perspective of patent application, the paper analyzed the future development of sewage treatment industry and the problems existing in the practical application of sewage treatment technology.

System The process of counting and storing in a manual water reservoir analysis has a high percentage of error rate compared to an automated system. In a company industry, especially in the WWT (Waste Water Treatment) section, it has several reservoir tanks as stock which are still counted manually. The ultrasonic sensor is placed at the top of the WWT tank in a hanging position. Basically, to measure the volume in a tank only variable height is always changing. So by utilizing the function of the ultrasonic sensor and also the tube volume formula, the stored AIR volume can be monitored in real time based on IoT using the Blynk application. From the sensor, height data is obtained which then the formula is processed by Arduino Wemos and then information is sent to the MySQL database server via the WIFI network.

Retaining of water resources quality is one of the global ecological problems of the modern time. The most promising direction in solving the problem of water resources protection is the reduction of negative environmental influence of waste water from production facilities by upgrading the existing water treatment technologies. To treat utility water, technical and rain water from site facilities of Transneft system entities, the specialists developed and approved standard technological diagrams, which are used in producing treatment facilities. The standard technological diagrams provide for all necessary stages of waste water treatment ensures the reduction of pollution level to normal values. However, during operation of treatment facilities it was established, that to ensure the required quality of waste water treatment with initially high levels of pollution, the new technological solutions are necessary. The author presents the results of scientific-research work, in the context of which the best affordable technologies were identified in the area of the treatment of waste water with increased content of pollutants and non-uniform ingress pattern. On the basis of the research results the technical solutions were developed for optimization of operation of existing waste water treatment facilities by means of using combined treatment of technical and rain waters and utility waste waters and applying bioreactor with movable bed – biochips. The use of bioreactor with movable bed allows the increase in the area of active surface, which facilitates increase and retention of biomass. Biochips are completely immersed into waste waters, and biofilm is formed on the entire volume of immersion area, facilitating retention of biomass and preventing formation of sediments. Due to mixing the floating device with biofilm constantly moves along the whole area of bioreactor, and, in doing so, speeds up biochemical processes and uniformity of treatment. The advantages of a bioreactor with movable bed – its active sludge durability against increased and changing pollutant concentrations, change of waste water temperature and simplicity of application – ensured the possibility of its use for blending utility waters, technical and rain waters.
