Description
Technical Field
The utility model belongs to the technical improvement field of the drainage on-line monitoring, especially, relate to online water balance monitoring system of pollution sources.
Background
With the national attention on city management, ecological network construction and the development of modern information technologies such as internet of things, big data, cloud computing and the like, the rapid development of informatization of the domestic environmental protection field and the water affairs field is certainly promoted, companies are guided by the technology, a professional entrepreneurship research and development team is gradually formed in continuous exploration and practice through continuous capital investment, technology and talent introduction, the industry development direction aiming at 'intelligent environmental protection' and 'intelligent water affairs' is finally established, and the intelligent water affairs information and supervision technology system construction work in the environmental protection field and the water affairs field is dedicated.
With the discharge and implementation of the 'ten items of water' and the 'thirteen five' plan of national environmental protection, the monitoring and treatment of the black and odorous water body in cities and towns become the central task. Because of the damage to water caused by rapid development and rapid expansion of cities and the imperfect construction of pollution control infrastructure, the water environment pollution of urban inland rivers is serious, and the phenomenon of pollution, dirt and odor is almost a common phenomenon of large and small river gushes. River pollution is mainly from domestic sewage and industrial wastewater, so that the supervision and management of the water environment are required to be comprehensively enhanced while the construction of infrastructure and river regulation engineering is accelerated, and on the basis of the comprehensive reinforcement, pollution sources in related water environment flow domains are mainly treated, and finally the pollution condition of the monitored water environment is thoroughly improved, so that the monitored water environment gradually recovers a self-purification and self-circulation ecological environment.
The online monitoring of the important pollution source in China begins in the nineties of the last century. In 2006, the country has developed the construction of online pollution source monitoring networks on a large scale, and wastewater discharged by heavy pollution sources in daily life is monitored. In 2011, the technical requirements and the detection method standards of the continuous emission monitoring system are released by the country for the first time. Promote the environmental management level of China to get a new step.
In recent years, with the rapid development of national economy, the living standard of people is further improved, the requirements of the masses on environmental protection are higher and higher, and the difficulty of corresponding environmental supervision is higher and higher. The traditional supervision means have difficulty meeting the requirements of pollution source monitoring and management under new situations.
In order to utilize an intelligent monitoring network for discharging important wading pollution sources, more effective management is carried out on water pollution and accurate sanction is carried out on pollution discharge law in all parts of the country, integrated automatic continuous monitoring equipment which is all-weather, all-process, all-around and accurately controls monitoring quality is urgently required to be installed in the construction of the network monitoring point.
In order to more effectively control water pollution throughout the country, an intelligent monitoring network for pollution source discharge of important wading water is utilized to accurately sanction pollution discharge violations.
At present, the point pollution source on-line monitoring system established in China mainly transmits the monitoring results collected by the water quality parameter on-line monitoring instrument to a central data management platform through transmission equipment for data statistics and arrangement, and provides relevant departments as management decision references.
This model has the following drawbacks and regulatory vulnerabilities.
A. The original system design is more suitable for large enterprises. The daily discharge of waste water is relatively large and continuous discharge is usually adopted. Therefore, an online monitoring instrument is arranged at the total sewage outlet, and sampling, analyzing and testing are carried out at regular time every hour or every four hours according to the set time sequence, so that the actual waste water discharge condition of an enterprise can be basically reflected. However, the existing continuous online detection instrument and meter of most industrial enterprises with daily wastewater discharge amount of more than one hundred cubes, dozens of cubes or even only a few cubes obviously have problems. These small and medium-sized enterprises intermittently discharge wastewater. And the time duration period of each drainage is short. For example, some businesses may discharge twice or three times a day, half an hour each time. Timing sampling designed in a continuous discharge mode often fails to achieve normal drainage.
B. Due to the adoption of the design of timing sampling, a lot of operation space is left for enterprises. For example, after mastering the automatic sampling rule, the enterprise can avoid supervision in a mode of firstly discharging tap water and then discharging waste water in the automatic sampling period.
C. In a more serious situation, part of enterprises often discharge a part of wastewater which meets the treatment standard at a main discharge port, and the rest of wastewater which does not meet the treatment standard is discharged through other pipelines. For many plants in Shenzhen, or sub-leased plants, illegal emissions have formed a complete industry chain.
In order to accurately sanction pollution discharge illegal behaviors all over the country, an important wading pollution source discharge intelligent monitoring network is utilized to control water pollution. In the construction of the network monitoring point, the monitoring equipment does not have the problems of all weather, whole process, all around and inaccurate monitoring quality.
