Pinay escort Since the 21st century, especially the “Eleventh Five-Year Plan” and the “Twelfth Five-Year Plan” are implemented. href=”https://philippines-sugar.net/”>Sugar baby has developed leapfrog. As of now, all municipal cities and more than 92% of county cities in the country have built sewage treatment factories. The total treatment capacity has exceeded 17 million m3/d, and the annual total sewage treatment capacity has exceeded 54 billion m3. my country has become the largest sewage treatment country in the world, which is comparable to the sewage treatment capacity of American.
The picture comes from the Internet
City Town Sewage Treatment is the main component of the bureau’s public services and has strong public welfare nature; sewage treatment is a relatively strong industry. The development of the industry is not open to technological progress and the correct guidance of relevant policies. The Housing and Urban-Rural Construction Department is the industry guidance department for sewage treatment in our city town. Over the years, many standard documents have been issued to promote the continuous development of sewage treatment industry in the city town.
1. Challenges in the urban sewage treatment industry in the new era
Sugar daddy
At present, with the basic popularity of sewage treatment facilities in cities and counties, about 50% of the country’s livelihoods enjoy public sewage treatment services. However, the flies accompanied by sewage treatmentWith rapid development, some new problems are gradually exposed.
1. The amount of single sewage treatmentSugar babySugar daddy purifier reduction has decreased
From 2007 to 201Sugar daddyIn the past 6 years, the scale of sewage treatment in urban towns increased from 77 billion m3/d to 177 billion m3/d, an increase of 130%. The sewage treatment volume increased from 17.8 billion m3/year to 54.2 billion m3/year, an increase of 204%. The annual discharge reduction of important chemicals (based on chemical oxygen demand COD) increased from 5.23 million to 13 million t, an increase of 148%. The increase in COD discharge reduction has decreased due to the increase in sewage treatment volume, and it is explained that the treatment efficiency of unit sewage treatment scale has decreased.

First, sewageManila With the rapid development of escort, the management network system still widely uses the original converged pipe network and even the stormwater pipe network. Many of these pipe networks are built in the last century, and even have culverts and drainage sluices built twenty or thirty years ago. The number of repair phenomena has been broken, leaked, misaligned, mixed phenomena are raised, rainwater and groundwater are pouring in, and even river water is backflowing, which leads to greater and greater sewage collection. The sewage collected by sewage treatment factories is more “sparse”; secondly, with economic development and industrial structure adjustment, the proportion of industrial wastewater entering the city’s sewage treatment factories has decreased. The current BOD/COD ratio has increased slightly from 2007 to 2011, with a stable foundation of 0.42. Sugar baby explains that the biochemical properties of sewage are more stable and close to the biochemical properties of sewage.
2. The contradiction between sludge relocation is becoming increasingly prominent
The more than 5.4 billion m3 of water treated each year can produce sludge with a moisture content of 80% of 30 million tons. The proportion of harmless and resource-based relocation is very low. Many places still rely on landfill relocation, which also forms the problem of not suffering from heavy burden on the slag landfill; sludge that is temporarily relocated still has the risk of secondary purification. Demand emphasizes that sludge is a problem accompanies the rapid development of sewage treatment. It should not be regarded as a “flood”, but should be purchased a full-link path that reduces, harmlessness and resources, so that sludge can truly become a treasure. This demand is guided by the center’s policy, which has caused the urban national authorities to pay great attention to and drive the development of sludge disposal.
2. Technical points and guiding meanings of the inspection methodEscort
In July 2017, the Housing and Urban-Rural Construction Department revised the “City Sewage Treatment Mission Inspection Measures”, which greatly adjusted the content of the original inspection method and realized a strong positive. In the percentage system, three technical contents: sewage treatment efficiency, important purification cutting efficiency, and sludge removal. href=”https://philippines-sugar.net/”>Sugar daddy scored 75 points, and the two governance scores of supervision and governance are 25 points. A detailed analysis of the inspection request from the technical department can find that the inspection after the review has strong practical meaning and guiding influence on the development of the sewage treatment industry in our city town.
1. Impact of desalination sewage treatment rate
Sewage treatment efficiency is divided into two parts: sewage treatment rate and purified material reduction efficiency. Among them, sewage treatment rate refers to the ratio of sewage treatment volume and sewage discharge volume. In this case, sewage discharge volume is based onThe total water supply in Chengzhen is converted. As a focus indicator that has reflected the degree of sewage treatment in the city for a period of time, the sewage treatment rate has been seriously affected and has been written into the national policy documents and related planning. However, as sewage treatment has entered a new stage, sewage treatment rate has faced problems such as real calculation methods and increased statistical methods, which has weakened the guidance and influence of solving current new contradictions and new problems. Therefore, although the post-revision inspection method preserves the sewage treatment rate indicator, the weight of power is weakened. On the one hand, it is conducive to the extension of the relevant national policies and facilitates acceptance by all parties; on the other hand, under the conditions of no better indicator replacement, it still has a certain effect, especially the western region and small and medium-sized towns that are relatively backward in the development of sewage treatment.
2. Raised purifier collection efficiency
This indicator is designed for the drop in the purifier concentration of the sewage treatment factory. Although the indicator evaluates the important purifier concentration of the sewage treatment factory, the actual quality is to reflect the sewage collection efficiency in a region and the quality and service level of the sewage collection pipe network. At the same time, in order to prevent the negative impact of the high-concentration industrial wastewater entering the city town sewage pipe network, the indicator covers five indicators: COD, BOD, ammonia nitrogen, total nitrogen and total phosphorus, and pays the right to disagree, so as to reduce the “shortness” caused by industrial wastewater discharge. This forces all over the world to improve the score by relaxing the pre-treatment standards for industrial wastewater monitoring and self-seeking “refreshing” of sewage treatment factories, but must focus on tasks such as the quality of pipe networks, improving the concentration of water inlet purifiers of sewage treatment factories, and reducing pipe network leakage.
3. Further strengthen the treatment effectiveness of sewage treatment plants
Adjust the previous investigation of the load rate of sewage treatment plants into the investigation of the removal effectiveness of sewage treatment plants. At present, the city’s sewage treatment factory has generally eliminated the phenomenon of “sunshine”, and even the phenomenon of overloading transportation in the department has shown an obscure impact on the normal operation and maintenance of the sewage treatment factory. Therefore, the request for setting the negative load rate is not suitable for the current actual situation, nor is it suitable for passers-by. Request for rainwater purification management in the early stage. Inspection method sets the replacement of purified substance removal effectiveness indicatorsThe negative load rate inspection is conducive to encouraging the quality of sewage treatment plants. The specific de-removal rate professor of COD, ammonia nitrogen, total nitrogen and total phosphorus has many technology companies. Teacher Ye has obtained a difficult time for others to investigate. Among them, COD de-removal effect must reach more than 90%, ammonia nitrogen de-removal rate must reach more than 95%, total nitrogen de-removal rate must reach more than 60%, and TC:
