How many days of normal operation does the state stipulate for urban sewage treatment plants? 50

Generally, the maintenance of reserved facilities is 10 days 15.

The treatment capacity of the sewage plant is based on the amount of clean water discharged after the treatment of the sewage entering the plant.

Hello, glad to answer for you. The daily treatment capacity of large-scale urban sewage treatment plants is generally between hundreds of thousands of tons and millions of tons per day, such as Gaobeidian (1 million tons) and Xiaohongmen (600,000 tons) in Beijing; Medium-sized sewage treatment plants can reach tens of thousands of tons to 100,000 tons, small sewage treatment plants can sell tons from 1,000 tons to 10,000 yuan, and as for 100 tons, they should be called sewage treatment stations. Hope mine is helpful to you.

The 100,000-tonne-per-day wastewater treatment plant produces 100 tonnes of wet sludge per day.

When purchasing sludge treatment equipment, the sewage treatment plant should first calculate the amount of sludge produced per day, and the amount of sludge produced here includes the sludge produced in each process of sewage treatment, as well as the final sludge produced after treatment.

There are many reasons that affect the sludge production of sewage treatment plants, among which the sewage treatment process and water quality have a greater impact. In the sewage treatment plant put into operation, 10,000 tons of sewage will produce more than 10 tons of sludge, and the water content of these sludge is high, generally more than 80%. The sewage treatment plant is required to be equipped with corresponding sludge treatment equipment, and the sludge can be reduced and harmless before it can be transported outside the sewage treatment plant.

Sludge dryer, sludge filter press, etc. are used in a number of sewage treatment plants, and the sludge with a moisture content of more than 90% can be pressed and dried into a mud cake with a moisture content of 40%, so that the sludge volume is reduced to the original 1 10, and the sludge reduction is realized to a large extent, which is not only convenient for transportation, but also solves the problem of large area and large pollution range.

From the above data, it can be roughly estimated that if a sewage treatment plant has a daily sewage treatment capacity of 100,000 tons, it will produce 100 tons of wet sludge. Therefore, sludge treatment equipment with a treatment capacity of not less than 100 tons per day is also required to operate smoothly and not affect normal operation due to sludge stacking problems.

The amount of sludge in the municipal sewage treatment plant is calculated according to the statistics of several cities in the south; The annual average of 10,000 tons of sewage treatment plant is 1 ton of dry sludge per day.

The combined moisture content is 80%, and the sludge is 5 tons. The 100,000-ton sewage treatment plant has a moisture content of 80% and produces 50 tons of sludge per day.

Generally a little more in summer and a little less in winter.

Extended Materials. Sewage treatment (wastewater treatment): The process of purifying sewage to meet the water quality requirements for discharge into a body of water or reuse.

Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and is increasingly entering the daily life of ordinary people.

There are many ways to treat sewage, which can generally be summarized as physical, chemical and biological methods.

Sewage treatment plants: Some people have surveyed more than 100 large treatment plants, half of them are exposed to the sun, and there are insufficient funds, high costs and low efficiency, the general efficiency is less than 70%, and the low efficiency is only 40%.

Summary. The actual number of days a wastewater treatment plant will be in operation depending on a number of factors, such as geographical location, size of the wastewater treatment plant, proportion of wastewater injected, process, climatic conditions, etc. As a result, the actual number of days of operation may vary greatly from plant to plant.

In general, the actual number of days of operation of a large wastewater treatment plant may be around 300 to 350 days, while the actual number of days of operation of a small wastewater treatment plant may be even shorter. The specific situation needs to be analyzed in combination with the actual situation.

The actual number of days a wastewater treatment plant is in operation can be affected by a number of factors, such as geographical location, size of the wastewater treatment plant, proportion of wastewater injected, workers' reputation, climatic conditions, etc. As a result, the actual number of days of operation may vary greatly from plant to plant. In general, the actual number of days of operation of a large wastewater treatment plant may be around 300 to 350 days, while the actual number of days of operation of a small positive wastewater treatment plant may be even shorter.

The specific situation needs to be analyzed in combination with the actual situation.

Can you elaborate on that a little bit more?

Hello dear! We're glad you asked: The type or actual number of days a wastewater treatment plant will be affected by a number of factors, such as geographical location, size of the wastewater treatment plant, proportion of wastewater injected, process, climatic conditions, etc.

As a result, the actual number of days of operation may vary greatly from plant to plant. In general, the actual number of days of operation of a large wastewater treatment plant may be around 300 to 350 days, while the actual number of days of operation of a small wastewater treatment plant may be even shorter. The specific situation needs to be analyzed in combination with the actual situation.

The sewage treatment plant receives a large amount of sewage every day, and after pretreatment such as screening and grilling, the sewage is sent to the treatment tank. 2.Sewage treatment:

After the sewage is received, it needs to go through multiple stages such as chemical treatment, biological treatment, and advanced treatment. Different treatment processes correspond to different units and equipment, such as chemical reactors, bioreactors, filters, sedimentation tanks, etc. 3.

Equipment overhaul: Weekly overhaul and maintenance of sewage treatment equipment to ensure stable operation of the equipment and reduce the possibility of failure. 4.

Effluent discharge: The treated wastewater is eventually discharged to the external environment through the effluent pipeline, and it is necessary to ensure that the discharge meets the local environmental protection requirements. 6.

Monitoring and Recording: Monitor and record the wastewater treatment status of the treatment plant so that problems can be detected and treated in time. The above is a brief summary of the normal operation of the sewage treatment plant on a weekly basis, and the specific situation will vary for different sewage treatment plants.
