Jiusha River all -round smart river management system initial results results

Recently, Hangzhou's temperature has exceeded 40 ° C for a few days. The river maintenance managers have also adopted the operating mode of avoiding high temperature. The maintenancers of the Jiusha River in the east of the city are not worried at all, because the Jiusha River upgrade transformation project just rushed to be completed before the high temperature day. The previous artificial inspections can be completed for them.

The Jiusha River improvement project began in March last year. It mainly involved the improvement and transformation of smart management facilities, focusing on the improvement of smart testing and water quality improvement technology.

The underwater camera broadcasts "underwater news" in time

The residents living along the Jiusha River should first notice that there are a few blue and white alarm pillars by the river. If someone is fishing in violation of regulations, the alarm pillar will also "speak" to remind everyone to protect the water quality and do not violate the net fish illegal net fish. Electric fish.

It is understood that the Jiusha River upgraded transformation project has set up 20 cameras, 4 8 -inch ball machines, 1 underwater camera and 4 sets of alarm pillars at important nodes along the river. One, it constitutes the three -dimensional intelligent detection network of the Jiu Sha River, which truly realizes the water quality of the urban river channels in intelligence.

In the past, the inspectors of the Jiusha River should check the water quality of the river in the river road without interruption of severe weather such as strong sun and heavy rain, and check whether there are violations of laws and regulations, whether the river greening and cleaning are in place.

Nowadays, with this smart system, in addition to routine inspections, inspectors only need to move the mouse in front of the computer, and the perspective of remote control and monitoring can pay attention to the situation in the river. The situation where the bad weather was not inspected in time, and it was possible to discover the emergencies in the river and take timely response measures.

If you see violations of laws and regulations by the river by the video surveillance system, as long as the inspector borrows the alarm pillar's shouting system, the illegal person can persuade the illegal personnel and "strangle" the hidden dangers in advance.

The Donghu Gate and the rubber dam are mainly used for daily water storage and flooding during the flood season. The transformation of this project is based on the principle of "no one is on duty, the young man is on duty", and the programmable controller (PLC) is the core. Combin the use of advanced sensor technology to automatically collect site conditions, and use industrial Ethernet technology to upload information to the dispatch center monitoring room through industrial Ethernet technology to achieve remote monitoring of rubber dams.

This system also adds an intelligent identification system. For example, the camera monitors the abnormal water outlets of the drainage outlet, a large area of ​​garbage occurred in the river surface, and violations of laws and regulations occur. insufficient.

The new underwater camera is also a professional helper of the water quality management of the river. With its help, the management of water quality and transparency can be detected for 24 hours of management. You can also understand the construction of the underwater ecosystem of the Jiusha River in real time, and see the underwater life of small fish and shrimp. Tourists walking on the roadside may find a large outdoor LED screen at the same time, and the underwater dynamics can be seen everywhere.

"The river of the Jiu Sha River is particularly long. It takes a few hours to inspect the river inspections for a while. It is usually okay. I am afraid that it will be completed in time. Now with this system, we can rest assured! "Jiusha River inspector Lao Shen said.

"Technology+" multi -channel improvement of water quality

Due to the frequent changes in water quality in the summer of the Jiusha River, in addition to improving the smart management system of the Jiusha River, this improvement and transformation also enhanced the self -improvement function of the water quality of the Jiusha River.

First of all, a "foreign aid" -water body circulation system for Jiu Sha River to help. From the section of Jiusha River Renai Road to Donghu Gate, a new set of water circulation systems with large tube diameter not only increases the liquidity of the river water body, but also enhances the water circulation of the river itself. At the same time, it is equipped with pipeline aeration facilities, which is conducive to improving the transmission rate of oxygen, increasing the solubility in the water body and microbial activity, so that the river bed forms a environment that is mainly comparative microorganisms, thereby suppressing nutrients such as mud nitrogen phosphorus and other nutrients Release, reduce the concentration of organic pollutants in the water body, and improve the water environment.

River aeration technology is based on the characteristics of hypoxia after the river is polluted. The air (or oxygen) is used to accelerate the oxygen of the water body to improve the solubility of the water body, restore and enhance the good oxygen microorganisms in the water body Vitality can purify the pollution substances in the water body, thereby improving the water quality of the river.

Secondly, the "internal driving force" of the Jiusha River -Fengyan Blue. This is a kind of floating plant that has a strong reproduction ability and is good at improving water quality quickly. If the management is poor, excessive reproduction and affecting water quality will occur; but as long as strict management, it is a good assistant to the river to improve water quality. In order to stabilize the water quality as soon as possible, Jiu Shahe combined with the experience of water governance in the past, and adopted the way of planting phoenix -blue blue in a framework, restriction, and small -scale planting. Regulatory, cleaning up, artificial intervention of its explosive growth, and the purpose of rapidly improving water quality in a short time.

In addition to Fengyan Blue, the Jiusha River often walks in the blocks of citizens, introducing water lilies and lotus to frame planting. At the season, the blooming flowers are connected into a landscape scroll.
