How to solidify the sludge? How much does a cubic meter of silt solidify

There are three methods of sludge treatment: sanitary landfill, direct land use, and incineration. Sanitary landfill is a simple, easy, low-cost disposal method, and the sludge does not require a high degree of dewatering, making it highly adaptable. However, there are also some problems with landfills, especially the formation of landfill leachate and gases.

Leachate is heavily contaminated liquids that can contaminate the groundwater environment if the landfill is not properly situated or operated. The gas produced by the landfill is mainly methane.

If appropriate measures are not taken, it will cause ** and burning. Extended information: The research on the influencing factors of the strength of silt solidified soil mainly focuses on the initial moisture content.

organic matter, dosage of cured materials, etc. The initial moisture content is larger, and the strength of the silt solidified soil is reduced. The organic matter is large, which reduces the strength of the solidified soil and even makes the solidified material fail; The amount of cured material is also the decisive factor, the amount of cured material is insufficient, the solidified soil has no strength, the amount is too large, and the excess part loses its effect. The deformation of silt-solidified soil includes deformation caused by force deformation and environmental changes.

The deformation includes unconfined compressive strength.

The axial direction of the solidified soil under different confining pressures in the triaxial test.

Evaporation method, quicklime mixing method, concrete mixing method.

The evaporation method is to evaporate the excess water, and the quicklime mixing method is the method of absorbing water through quicklime.

The concrete mixing method is to add cement for mixing, and the purpose of reducing moisture is achieved through the heat of cement hydration.

Sludge fixed-line treatment method can be treated with a filter press! It is also possible to dry the method.

Is this an engineering need? Yes, it can be drained and consolidated, or it can be solidified with cement. Of course, the best thing to do is to replace it.

If you have a special sludge solidification machine, you can buy one.

Sludge sludge solidification treatment construction plan? A great way to clean up the silt.

Dear, I will sort out the answers to the questions you need for <>you

<> Answer, mud curing agent ** do excavation: 1 cubic meter of wet sludge cooling: digging silt loading each cubic meter of silt needs to be transported twice by excavators, transportation, flattening, and paving steel plates, each cubic meter of finished solidified soil needs to use cubic meters of wet silt, sludge:

Weight 3%, cubic meters of finished solidified soil need to be dried 1 800 kg of soil, cement is 3% of the weight of soil, cement 1800 x 3% = 54 kg, per ton of cement ** for Xiaohuchang 335 yuan cultivated land rotary rake stirring: each cool dry layer of wet silt thickness of meters, cultivated land, rotary rake twice, 80 yuan per cultivated land, per yuan three, each 60 yuan per harrow, per yuan three, cement labor costs: 54 kg of cement per cubic meter of finished solidified soil, after each cool layer of wet silt, every 200 yuan man-day, Laying of cement 600 m.

Hello dear, happy to answer your <>

Sludge solidification is a technology that mixes sludge with a curing agent and treats it to achieve the purpose of solidifying sludge. Sludge is a mixture of sludge made up of a large amount of sediment, organic matter, microorganisms, etc., this material is difficult to dispose of, and improper treatment may cause environmental pollution. The solidification of sludge is to make it more stable by adding a curing agent, so as to achieve the purpose of storage, transportation and treatment.

Common sludge curing agents mainly include cement, hydrated lime, coal ash, etc., which will chemically react or physically combine with the organic matter and microorganisms in the sludge to form a more stable solid, so as to achieve the goal of solidifying the sludge. When solidifying the sludge, it is necessary to consider the nature of the sludge, the type and amount of the curing agent, and carry out appropriate mixing, stirring and other treatments, so that the sludge and the curing agent are mixed evenly, so as to achieve a better curing effect. Sludge solidification treatment technology is widely used in sewage treatment, mud treatment, river dredging and other fields, which can effectively solve the problem of sludge treatment, reduce the risk of environmental pollution, and can also reduce the volume after treatment by compressing and forming blocks.

It should be noted that sludge solidification treatment will also bring new environmental problems, such as the safe transportation and storage of solidified sludge from letter burning, so it is necessary to strictly comply with relevant environmental protection standards and regulations. <>

Dear We will be happy to answer your <>

According to the teacher, the solidification treatment of sludge refers to the treatment of water and organic substances in the sludge by adding chemicals such as curing agents to make it into a solid state, so as to achieve the purpose of reducing volume, stabilizing and reducing pollution to the environment. The steps of sludge solidification treatment generally include the following aspects: 1

Pretreatment of sludge: The sludge is screened, crushed, stirred, etc., so as to be better mixed with the curing agent. 2.

Addition of curing agent: According to the nature of the sludge and the curing requirements, select the appropriate curing agent for addition, such as cement, lime, silicate, etc. 3.

Mixing and stirring: Mix and stir the sludge and curing agent thoroughly to make it evenly distributed. 4.

Forming and curing: The mixed sludge and curing agent are molded, such as pressed into blocks or poured into shape, and then cured to make it into a solid state. Sludge solidification treatment can effectively reduce the volume of sludge and pollution to the environment, and at the same time, it can also convert sludge into usable resources, such as road construction, land reclamation, etc.

Hello, we are glad to answer for you, sludge solidification treatment refers to the treatment of dense sludge formed after mixing pollutants and water to make it more stable and safe for storage, transportation and disposal. The common sludge solidification treatment methods are as follows:1

Curing agent treatment method: The curing agent is added to the sludge, and the sludge is solidified into a hard solid through chemical reaction for easy storage and transportation. The curing agent can be cement, lime, calcium chloride and other materials.

2.Drying treatment method: The sludge is placed in the drying equipment for drying, so that the water in the sludge evaporates, so that the sludge becomes drier and more stable.

This method is suitable for situations where there is a lot of water in the sludge. 3.Compaction Method:

The silt is compacted using compaction equipment to make it tighter and harder. This method is suitable for situations where the silt contains a large amount of particulate matter such as soil. 4.

Biological treatment method: use microorganisms and other organisms to decompose and oxidize the sludge, so as to reduce the harmfulness and danger of the sludge. This method is suitable for situations where the sludge contains a large amount of organic matter.

When carrying out sludge solidification treatment, it is necessary to choose the appropriate treatment method according to the nature and actual situation of the sludge, and strictly abide by the relevant environmental protection regulations and safety standards to ensure the environmental protection and safety of the treatment process and treatment products. Hope it can help you and have a happy life!
