The problems you encounter in sewage treatment and the ways to solve them are best to share your eng

Eight major measures for the prevention and control of sewage: 1. Strictly control the total amount of pollutant discharge, continue to reduce industrial pollution, promote the zero discharge system of wastewater recycling and closed circuit for key polluting industries such as steel, electric power, chemical industry, and coal, and effectively strengthen the audit and supervision of polluting discharge units. 2. Accelerate the construction of water-saving industry and water-saving society.

We should further study the methods for managing water conservation in industry, standardize the scope of water conservation in enterprises, and strictly enforce water quotas and water-saving standards for key industries that discharge water pollution. 3. Vigorously promote urban sewage treatment and recycling. In order to fundamentally avoid the continued deterioration of the urban water environment, it is also necessary to improve the urban drainage system and improve the technical level of urban sewage treatment.

Cities with water shortages should arrange the construction of reuse facilities and carry out advanced treatment of sewage treatment while planning sewage treatment facilities. 4. Develop ecological agriculture and organic agriculture, and comprehensively prevent and control non-point source pollution. In the future, we will mainly promote organic fertilizers, formulate reduction plans for pesticides and chemical fertilizers, and effectively solve the problem of agricultural non-point source pollution.

5. Take measures to effectively protect the marine ecological environment. 6. Allocate water resources scientifically and rationally to ensure ecological water use. The development and utilization of water resources should be based on the premise of protecting the water environment function, taking into account the needs of the upper and lower basins of water resources, and permits should be issued according to the total amount of water resources that can be developed.

7. Priority should be given to protecting the water quality of drinking water sources. It is necessary to formulate regulations on the protection of drinking water sources in urban and rural areas throughout the country, and strictly restrict all kinds of development activities in the protection zones of water sources. 8. Persistent organic pollutants should be strictly controlled.

The heavy use of pesticides in China has led to a high proportion of persistent organic pollutants in water bodies, which must be strictly controlled. Article 20 of the Regulations on Urban Drainage and Sewage Treatment: Drainage units and individuals within the scope of urban drainage facilities shall discharge sewage into urban drainage facilities in accordance with relevant national regulations.

In areas where rainwater and sewage are diverted, sewage shall not be discharged into the rainwater pipe network. Article 21: Enterprises, public institutions, and individual industrial and commercial households (hereinafter referred to as "drainage households") engaged in industrial, construction, catering, medical and other activities that discharge sewage into urban drainage facilities shall apply to the competent department of urban drainage for obtaining a permit for discharging sewage into the drainage pipe network.

The competent departments of urban drainage shall, in accordance with the relevant national standards, focus on matters affecting the safe operation of urban drainage and sewage treatment facilities. Drainage households shall discharge sewage in accordance with the requirements of the permit for discharging sewage into the drainage pipe network.

Wastewater treatment is a complex technology that often faces a variety of problems and challenges, but here are a few of the most common ones:

1.Equipment aging problem: With the increase of use time, the equipment may be aging or damaged, such as pipe blockage, equipment wear and tear, liquid hopper, etc.

2.Sludge treatment problems: Sludge treatment after sewage treatment may have difficulties in storage, transportation and treatment, especially for areas with high waste discharge standards.

3.Lack of funding: The implementation of laws and regulations related to wastewater treatment and wastewater discharge requires a lot of costs. Moreover, in some areas, there is a shortage of sewage treatment plants, even in areas that have not yet been fully built.

4.Running cost issues: Running costs are an important consideration for wastewater treatment facilities. Typically, treating more wastewater requires more electricity consumption, use of chemicals used to treat wastewater, etc.

5.Discharge standards: Since sewage treatment involves wastewater discharge and environmental protection, there may be differences in discharge standards in various regions, in this case, how to control pollution and achieve a virtuous cycle of environmental protection and economic development has become a problem.

These problems have an impact on the efficiency and quality of wastewater treatment and need to be fully addressed and addressed.

1. The infrastructure needs to be improved.

The supporting rate of many urban sewage collection pipe networks is not high, and there are two specific situations:

1) Only pay attention to the construction scale of the main road of the drainage pipe network and the sewage treatment plant, and ignore the construction of the household branch pipe and the collection branch pipe, resulting in the ineffective use of the original sewage collection pipe network and the inability to give full play to the role of sewage collection.

2) Many of the drainage pipes in some older urban areas are common pipes of rainwater and sewage, and most of the urban domestic sewage is also included in the rainwater pipes, resulting in the sewage pipe network can not be matched with the sewage treatment network after the transformation of the household branch pipe, and the urban domestic sewage can not be smoothly connected to the main road.

2. The preliminary work needs to be strengthened.

The preparation of the feasibility study report is one of the important prerequisites for the construction of water pollution treatment related projects. The feasibility study report covers the size of the project investment amount, the operability of the implementation steps and the operational efficiency after completion. The results are a direct indication of the future development and final outcome of the project.

However, at present, there are still problems in many regions that attach importance to image and political achievements and ignore reality. Many projects do not do enough in the early feasibility study, and start blindly without considering the actual situation. In order to pass the review and start construction as soon as possible, some projects use false data to prepare feasibility reports, resulting in the loss of the original meaning of feasibility studies.

Many large-scale, large-scale wastewater treatment projects with huge investments have faced a shortage of polluted water resources since the day they were built.

3. The later maintenance work of the pipeline network has not kept up.

The drainage network is not only responsible for discharging sewage, but also an important facility for collecting urban sewage. During use, the pipeline is damaged and needs to be repaired in time to ensure the normal use of the pipe network. In practice, the maintenance of the pipe network is not enough.

Pipe networks far away from urban areas or remote places often face damage and no one repairs them, while the construction of municipal facilities leads to damage to the pipe network, and sometimes it is not repaired in time.

4. The sewage treatment results cannot meet the normative standards.

Due to the fact that some sewage treatment facilities are located in the suburbs, they have not received due attention, and the pipes of their water bodies are occupied by other facilities, coupled with the lack of supporting sewage network pipes, resulting in the quality of the sewage discharged by these facilities after treatment is far from meeting the requirements of the relevant standards.

Technology is backward. Most of China's sewage treatment technologies lack independent patented technology, but learn from foreign technology, which may not be suitable for China's national conditions, which not only causes waste of water resources, but also reduces the efficiency of sewage purification. Some urban wastewater treatment technology is limited and cannot maintain long-term, stable and standard operation, and some enterprises will increase energy consumption, increase the dosage of drugs and extend the treatment time to a certain extent in order to ensure that the wastewater treatment standards are met, which increases the wastewater treatment cost of the enterprise.

High ammonia nitrogen, low COD is not easy to handle.

You can go to the Xianfeng Agricultural Bureau for consultation, because before biogas and other things were also under the full management of the Agricultural Bureau, remember to buy cigarettes at the commissary in front of the Agricultural Bureau, and then inquire about the situation first! The address of the Agricultural Bureau is on Chushu Avenue, and it only costs 2 yuan by taxi.

What kind of process, process flow, and the advantages and characteristics of the process, and the role of the specific process.
