Main technologies and analysis of wastewater treatment in Shandong Leran Environmental Engineering
At present, with the continuous development of urbanization and the increasing population in our country, the pollution problem has become increasingly serious, especially the sewage produced in daily life. If things go on like this, it will seriously threaten people's lives and health. my country has always been short of water resources and the efficiency of urban sewage treatment is low.
At present, with the continuous development of urbanization and the increasing population in our country, the pollution problem has become increasingly serious, especially the sewage produced in daily life. If things go on like this, it will seriously threaten people's lives and health. my country has always been short of water resources and the efficiency of urban sewage treatment is low. This article will analyze the current problems of sewage treatment in our country and propose several improvement measures.
Water, as the source of all things, must be well managed. Faced with the problem of food water treatment in the environmental process, in order to enhance the efficiency of water use and avoid re-pollution, scientific and effective treatment of urban sewage must be established , especially in the face of the current shortage of water resources, only by fully utilizing sewage and enhancing utilization efficiency can the normal supply of water be ensured. Therefore, sewage treatment methods and technologies should be further studied to ensure people's production and living water.
1. Analysis of current problems of sewage treatment in environmental engineering
1.1. Sewage treatment efficiency is not high and funds are insufficient.
Compared with the discharge volume of urban sewage, my country's current sewage treatment efficiency is relatively weak, and the discharge volume cannot match the treatment. At the same time, there is still a significant gap between my country's sewage treatment capacity and other countries. In addition, the lack of funds is also a very important obstacle. Although my country began to increase investment in sewage treatment infrastructure in 1998, the funds for sewage treatment still cannot meet the current usage. Channels are scarce and investment is small. These are all important factors affecting sewage treatment.
1.2. The design of drainage pipes is not scientific and reasonable.
Many cities lack foresight and sustainability when designing drainage pipelines. Therefore, the design of sewage drainage pipelines is relatively simple. Sewage cannot be discharged and treated in separate streams. This will result in different sewage and it is difficult to adopt different sewage treatment systems. , is likely to cause secondary pollution. Since the diversion and discharge systems in some cities are relatively crude, the polluted water in the city cannot be effectively treated, which affects the full utilization of water resources.
1.3. Lack of unified scientific planning
The feasibility study mainly refers to the investment funds, operating steps, and subsequent operations of the project. The preliminary feasibility study of urban sewage treatment is closely related to the development of future sewage treatment projects. In most urban sewage treatment processes, most regions simply focus on political performance and use false data to complete feasibility reports in order to improve project progress. The investment of funds has not been standardized, and blind use has led to problems in water pollution control. Generally speaking, the reference data for urban sewage treatment is mainly calculated comprehensively based on historical comprehensive water use data and regional scale. The results of this actually have certain flaws, which can easily lead to inaccurate planning and unreasonable sewage treatment, which is inconsistent with the actual situation. gap.
2.1. Improve sewage treatment technology
In order to achieve effective treatment of urban sewage and improve the utilization rate of water resources, it is necessary to comprehensively strengthen scientific research and further popularize and improve sewage treatment technology. For example, based on the current development status of the city, scientific and reasonable design of sewage equipment pipelines and water supply and drainage pipes should be carried out realistically to ensure the tightness of pipeline connections and avoid water leakage. At the same time, advanced technology can also be used to effectively treat sewage. .
2.2. Increase capital investment
At present, the problem of weak financial foundation has a certain adverse impact on the quality and efficiency of urban sewage treatment in environmental projects. With the continuous construction of ecological civilization in the new era, this requires our country to increase investment and support for urban sewage treatment. This can not only create a good social environment for the city, but also achieve the current stage of urbanization development. requirements standards.
2.3. Choose appropriate processing methods
At present, with the continuous advancement of various technical levels, the methods of sewage treatment are becoming increasingly abundant. However, not all treatment methods are worthy of widespread use. For this reason, appropriate and reasonable methods should be selected during sewage treatment to effectively enhance the efficiency and quality of treatment.
In the environmental process, there are some problems in urban sewage treatment. On the one hand, there is a lack of awareness of protection, and on the other hand, the technology is not advanced enough. At the same time, the design of drainage and sewage pipes is relatively backward. In order to solve the urban sewage treatment problems in environmental engineering, it is necessary to carry out sewage treatment. Carry out effective secondary utilization and strengthen sewage treatment technology. By raising awareness of the use of sewage, we can truly save water resources and improve people's quality of life.
