Core Reading In recent years, Shenyang, Liaoning Province has promoted water environment treatment through river dredging, sewage interception, landscape greening and other measures to create urban waterfront open space and improve urban landscape with clean water and green banks. There are more urban parks and waterfront trails, and the interconnected green living water network has gradually formed. "Look! Birds are coming to the river again!" Shi Quangang showed the photos sent by photographers the other day: several oriental white storks live by the Hun River in Shenyang, Liaoning Province. As the deputy director of Shenyang Bird Island Animal Management Department, Shi Quangang knows that it is not easy: "This kind of bird is picky about water quality, and they are willing to come here to live, which is recognition of the environment here." The arrival of Oriental white storks reflects the change of Shenyang's water environment. In recent years, Shenyang has promoted water environment governance, built a green living water network, created urban waterfront open space, and enhanced the city with flowing rivers and beautiful riverbanks. In 2021, 20 sections above the provincial examination level in Shenyang will have no water body inferior to Class V, and 11 sections will have excellent water quality. Effectively curb the discharge of pollutants, and the river water quality continues to improve. "The indicators of chemical oxygen demand and total phosphorus exceed the standard!" One night at the beginning of this year, the online monitoring system of the Ecological Environment Branch of Shenyang Economic and Technological Development Zone showed that two water inflow indicators of a sewage treatment plant in the area exceeded 8.75 times and 4.26 times respectively. The situation was reported to the "Four Sides Linkage" work coordination group established by the management committee, the ecological environment branch, the construction management department and the sewage treatment plant in Shenyang Economic and Technological Development Zone. Within one hour, all parties arrived at the sewage treatment plant for investigation. The investigation results show that there is a lot of sludge deposited in the intake sump, which is inhaled by the collector, resulting in some abnormal indicators. Exceeding the standard is not due to pollutant emission. However, the hidden danger cannot be ignored. In the morning of the next day, relevant staff carried out pipe network dredging, sludge cleaning and other operations. Within 36 hours, the hidden danger was eliminated, and the influent water returned to the standard state. "This water is to be drained to the Xihe River." Zhang Ersi, Deputy Director of the Ecological Environment Branch of Shenyang Economic and Technological Development Zone, said, "Why are you so nervous and attached so much importance? It is not easy to achieve results in the control of the Xihe River, and there must be no further retrogression!" Xihe River is an urban inland river in Shenyang. It once undertook the production and domestic sewage discharged by the city all the year round. There are many pollution enterprises in the river basin and it is difficult to collect and treat the tailwater. Before 2017, the water body of Xihe River was seriously polluted, and the water quality was inferior to Class V all the year round. The upgrading of the sewage treatment plant, the implementation of the sewage transfer and wastewater intercepting and piping projects, the "comb action" of the chemical park, the "tracing action" of the enterprise drainage, the "zero action" of the standard rectification... a set of "combination punches" have effectively curbed the discharge of pollutants, making the water quality of the Xihe River continuously improve. Since this year, the water quality of Xihe River has steadily reached the Class IV standard for surface water. Today, near the section of Xihe River in the Taiwan National Examination, the two banks are covered with green trees, and the waterfront trails are clean and flat. Gao Linlin, a resident who has lived nearby for more than five years, said: "The river water was so smelly that she dared not open her windows in summer. Now the river water is clear, and our living environment is much better." To eliminate the black and smelly water body, normalize the management and maintenance, consolidate and upgrade the South Canal in Shenyang, a small boat is moving slowly. Bow, cutter mesh cutting
