Who buys the mud after sewage treatment?

Sold to water treatment installation and commissioning units, sludge is sold to relevant enterprises or Party B of any nature. The sludge of sewage in daily life is easier to do, and the sludge of industrial enterprises depends on the nature, hehe, I hope you can find a buyer as soon as possible.

Sludge composting can be carried out, and the project we are working on now is a sludge composting reuse project, and the Pangezhuang composting plant in Daxing, Beijing, can compost sludge.

Dizzy, at present, in China, you spend money to give people enterprises with environmental protection qualifications**Go back to make bricks, incineration, landfill treatment, you still want to sell for money.

The sludge from the sewage treatment plant is a good fertilizer, but because the environmental protection risk is difficult to promote, and some environmental protection parts control it as hazardous waste, it is difficult to use it valuablely, and most of it needs to be treated. Therefore, you need to contact a professional processing unit, and do not contact informal units and individuals, once they collect the money, it will bring you trouble. At present, most of them are incinerated.

After treatment, the mud has to be sent to a professional company for further processing.

It's a sanitary landfill, according to the regulations, but I've seen some people pull the sludge away and use it to fertilize the crops.

The sludge after sewage treatment is rich in nitrogen, phosphorus and potassium, as long as the content of heavy metals after the identification of leaching poison meets the pollution control standards of agricultural sludge, it can be used for land application of land for land cultivation and agricultural fertilizer, and this sewage treatment plant can cooperate with relevant fertilizer manufacturers or land management growers.

Sludge that meets the landfill cover criteria can be used as a domestic waste landfill cover and purchased by the landfill. In addition, the sludge is composted at high temperatures and then used directly for agricultural fertilizer.

In short, after a certain amount of treatment, the indicators of urban sludge meet the corresponding standards, there will be many ways to utilize, and good economic value can also be realized. Those sludge with excessive heavy metal content that cannot be comprehensively utilized need to be treated in sanitary landfills.

Isn't it generally landfilled now?

It depends on what kind of sewage you are and whether it has resource utilization value! Please elaborate.

As you know from the above discussion, you want to know that you have very little sludge in your wastewater treatment process. The first thing to know is what this sludge is? These so-called "sludge" are actually a variety of bacteria, all of which are produced in different environments and multiply.

Therefore, the requirements of bacteria for the environment are "single selective". In other words, the wastewater in your process must have a lot of variation in some of the key components, and it's still very large. Bacteria acclimatize to the environment, also known as "acclimation", generally take more than 4 weeks and are most active at temperatures of 30-40 degrees Celsius.

I wonder if your process wastewater can meet the above conditions? If not, then it is necessary to adjust.

In addition, there is a type of sewage called "low temperature and low turbidity", which has always been difficult to treat by conventional methods. Sewage is just a seemingly clear surface and at the same time very cold. This type of sewage is characterized by a high content of heavy metals (highly toxic), a very low content of organic matter (that is, bacteria do not "eat"), and a very low temperature, which is not suitable for the reproduction of bacteria.

What sludge are you referring to?

Does it refer to the activated sludge used in the biochemical treatment of sewage? In the sewage treatment process, a part of the activated sludge will be generated, and if it is not enough, it will have to be purchased from other sewage treatment plants.

I hope to add clarity to the question.

Muddy is grown by absorbing various nutrients from sewage, and the important component is microorganisms.

At the beginning, it has not been cultivated well, generally it takes 3 months, add some nutrients into it, and dig some similar sludge to let the microorganisms grow faster.
