Face problems

China's sewage treatment is faced with serious water pollution, late start of sewage treatment, poor foundation and high requirements. In recent years, the construction of urban sewage treatment has made great progress. By the end of June 2005, 661 cities had built 708 sewage treatment plants, with a treatment capacity of 49.12 million cubic meters per day, more than twice that of 2000. Last year, 16.28 billion cubic meters of urban sewage was treated, an increase of 43 percent over 2000, and the urban sewage treatment rate reached 45.7 percent. However, the sewage treatment capacity of the vast majority of cities cannot meet the actual needs. There are still 297 cities in China that have not built sewage treatment plants, of which 63 are cities at the prefecture level or above, including eight big cities with a population of more than 500,000. 54 cities are located in key river basins and within the scope of the regional "Tenth Five-Year Plan". There are no sewage treatment facilities in more than 50,000 cities and towns, 3.7 million villages and 900 million people.

Compared with the international, China's urban sewage treatment rate is low, the main reason is that China's urban sewage treatment plant construction lag. According to the information, the United States has an average of one sewage treatment plant per 10,000 people, and the United Kingdom and Germany have one sewage treatment plant per 7,000 people. One sewage treatment plant for 8,000 people. In China's urban population, there is only one sewage treatment plant for every 1.5 million people. According to the national sewage treatment situation reported by the Ministry of Construction, the completed sewage treatment plant, in addition to the commissioning operation, there are not normal operation, the main reasons are: first, the poor management of sewage treatment organization, resulting in some sewage treatment plants have been built for half a year or even nearly a year is still not running. Second, some cities that have built sewage treatment plants have not yet levied sewage treatment fees, or the charging standard and collection rate are low, and the operating funds of sewage treatment facilities are difficult to guarantee. Third, the construction of sewage collection pipe network lags behind, and the operation load rate of sewage treatment plants is low, and even difficult to operate. Fourth, the local supporting funds are not implemented, affecting the commissioning and operation of sewage treatment plants. In addition, there are some urban sewage treatment plant design scale is too large, too advanced, resulting in partial idle facility capacity can not give full play to the benefits.

Current situation

Shortage of funds for the construction of sewage treatment plants; Maintenance of imported equipment and development of spare parts; There is a gust of wind in the selection of sewage treatment process, and the popular process is not selected according to the actual situation of the region. [1]

1. Operational services and efficient supervision have become prominent issues. Operation management is becoming more and more important and prominent. Due to the large number and wide distribution of subordinate enterprises, higher requirements are also put forward for supervision.

2, sewage treatment enterprises in the operation stage, the requirements for management level, cost control requirements are constantly improving.

3, sewage treatment enterprises how to promote the management experience of excellent sewage treatment plants in the industry to all plants and stations to improve the overall management level of the company.

Use cases of iot in urban sewage treatment:

As a key unit of smart city pilot, Wuhan adopts the integrated operation and management platform of Internet of Things sewage treatment in the sewage treatment industry, relies on cloud computing technology to build and use the Internet to integrate various wide area heterogeneous computing resources to form an abstract, virtual and dynamically scalable computing resource pool. Then through the Internet to provide users with computing power, storage capacity, software platform and application software and other services. The system can monitor the three main links of the inlet, production and discharge of sewage treatment enterprises, collect, integrate, analyze and treat the information of the water, water level, water quality, power consumption, drug consumption and equipment status of the subordinate lifting pump station and sewage treatment plant through the cloud computing platform, and establish the mutual protocol model of each link. The hidden relationship between the consumption of water, electricity and medicine in the production process and the drainage, production and discharge of the treatment water is analyzed to find out the optimal production process management scheme of the sewage treatment plant, achieve the real-time control and fine management of the production process of the sewage treatment enterprise, and achieve the purpose of standardized management, energy saving and consumption reduction, staff reduction and efficiency increase.
