Urban domestic wastewater treatment and environmental protection are crucial components for the sustainable development of modern cities.This study focused on the field of urban domestic wastewater treatment,delving into p otential issues in the treatment process and their impact on the ecological environment,it systematically summarized mainstream wastewater treatment technologies such as biological treatment,chemical treatment,and physical treatment,and through practical cases,conducts a comprehensive comparative analysis from dimensions like applicable scenarios,treatment efficiency,and costs.At the same time,this study also explored essential environmental protection measures that must be implemented during the wastewater treatment process,including pre-treatment technologies for sewage,methods for sludge resource utilization,and strategies for pollutant emission control.Research shows that integrated use of multiple technologies in wastewater treatment systems can improve purification efficiency and reduce pollution risks.This study has provided a basis for optimizing the wastewater treatment system and formulating environmental strategies,contributing to green urban development.
Environmental monitoring is the cornerstone of ecological and environmental protection,which plays an important role in preventing pollution,evaluating environmental quality,and promoting scientific and technological innovation.This paper systematically expounds the important position and role of environmental monitoring in ecological environment protection,and puts forward the development measures to strengthen environmental monitoring from the aspects of strengthening technological innovation,improving the monitoring network,strengthening the construction of laws and regulations,strengthening the construction of talent team and improving the public participation.At present,China is vigorously promoting the modernization of environmental monitoring,introducing advanced technology and equipment,increasing investment in scientific research,optimizing the layout of the monitoring network,improving the legal system,strengthening personnel training,encouraging public participation,these measures have made an important contribution to winning the battle against pollution and building a beautiful China.

With the rapid development of the social economy,the people's awareness of environmental protection has been continuously enhanced,and the concept of sustainable development has become more deeply rooted in the hearts of the people,the country attaches unprecedented importance to environmental protection.Environmental monitoring is the technical support of environmental management,and theextensive development of environmental monitoring has gradually become an important task of the ecological and environmental management department.Environmental monitoring quality management is the basis of environmental monitoring work.Only by implementing diversified strategies can we improve the quality of environmental monitoring,ensure the representativeness,accuracy,precision,compareability and integrity of monitoring data,fully implement the environmental monitoring plan,provide accurate environmental information to the ecological environment department,and grasp the quality status of the environment in real time,designed scientific improvement strategies can promote the continuous improvement of environmental quality.
Taking coastal waters of Zhuhai Gaolan Port economic zone as an example,a hydrodynamic and pollutant transport model is first setup by the utilization of MIKE 21 software,and the model includes the Jitimen waterway,the Hutiaomen waterway and the Yamen waterway.Then the model is well verified by measured data of tidal current and concentration of Chemical Oxygen Demand(COD).Finally,the differences of water environmental capacity under six different design hydrological conditions are studied.The results indicate that the total capacity of COD calculated under the hydrological conditions of scenario 1 to scenario 4 is similar,which is 413.6t,403.7 t,390.3 t and 387.3 t respectively.The total capacity of COD calculated under the hydrological conditions of scenario 5 and scenario 6 is similar,which is 234.9 t and 193.6 t respectively.It follows that the outer sea boundary tidal level data has a great influence on the calculation results.
