[0002] Before sludge treatment, it is necessary to understand the classification of sludge first in order to determine the sludge treatment method: Treatment of physical and chemical sludge discharged from sedimentation tanks or thickening tanks in water treatment plants. Sludge classification: It belongs to medium-fine-grained organic and inorganic mixed sludge, with general compressibility and dewatering performance. Treatment of excess activated sludge discharged from the secondary sedimentation tank in domestic sewage treatment plants. Sludge classification: It belongs to hydrophilic, fine-grained organic sludge, with poor compressibility and dewatering performance. Treatment of physical and chemical and biochemical mixed sludge discharged from the thickening tank in industrial wastewater treatment. Sludge classification: It belongs to medium-fine-grained mixed sludge, and the dewatering performance of the sludge containing fibrous bodies is better, while the rest has general compressibility and dewatering performance. Treatment of physical and chemical fine-grained sludge produced by physical and chemical methods discharged from the thickening tank in industrial wastewater treatment. Sludge classification: It belongs to fine-grained inorganic sludge, with general compressibility and dewatering performance. Treatment of physical and chemical precipitated coarse-grained sludge produced by industrial wastewater treatment. Sludge classification: It belongs to coarse-grained hydrophobic inorganic sludge, with very good compressibility and dewatering performance.

[0025] The jet reflection assembly includes a mounting seat 501 connected in cooperation inside the conduit 1. One end of the mounting seat 501 is connected in cooperation with a support rod 502. One end of the support rod 502 is connected in cooperation with a baffle 503. The baffle 503 is located at the extension intersection of the spray heads 403, and the chemical agent is reflected by the baffle 503. Embodiment 2

[0026] In addition to including all the technical features in Embodiment 1, this embodiment further includes: the chemical dosing and filling assembly further includes a pump pipe 402 connected in cooperation at one end of the pressure pump 401. The pressure pumps 401 are multiple and distributed in an array. The pressure pumps 401 are inclined. The chemical agent is injected through the pressure pumps 401 to increase the introduction of the chemical agent, and the chemical agent is transmitted through the pump pipe 402.

[0027] Furthermore, the chemical dosing and filling assembly further includes a pump pipe 402 connected in cooperation at one end of the pressure pump 401. The pressure pumps 401 are multiple and distributed in an array. The pressure pumps 401 are inclined. The spray heads 403 are multiple groups. One end of the spray head 403 extends towards the center of the conduit 1. The extension of one end of the spray head 403 towards the center of the conduit 1 makes the sprayed chemical agent convenient to spray on the baffle 503, facilitating the baffle 503 to reflect the chemical agent and increasing the use convenience.

[0028] Further, a first connecting sleeve 2 is fitted and connected to the surface of the conduit 1. There are multiple first connecting sleeves 2. One end of the first connecting sleeve 2 is fitted and connected to a second connecting sleeve 6. A silt inlet pipe 7 is fitted and connected to the surface of the second connecting sleeve 6. The silt inlet pipe 7 is fitted and connected to one end of the conduit 1. A pump body 8 is fitted and connected to the surface of the silt inlet pipe 7. A connecting pipe 3 is detachably connected to the surface of the conduit 1.

The silt inlet pipe 7 is internally controlled through the pump body 8 fitted and connected to its surface. Water injection treatment is carried out inside the conduit 1 through the connecting pipe 3.

[0029] Working principle: One end of the nozzle 403 extends towards the center of the conduit 1 so that the sprayed medicament can be easily sprayed onto the baffle 503, facilitating the baffle 503 to reflect the medicament, which increases the usability. The medicament is injected into the conduit 1 through multiple pressure pumps 401 fitted and connected to the surface of the conduit 1. The medicament is introduced through the pump pipe 402 fitted and connected to one end of the pressure pump 401. The medicament is poured into the nozzle 403 fitted and connected to one end of the pressure pump 401 through the pressure pump 401. The medicament is sprayed into the silt inside the conduit 1 through the nozzle 403. An inclined opening 404 is provided at one end of the nozzle 403 to change the spraying direction of the medicament, increasing the fusion between the medicament and the silt. There are multiple nozzles 403 arranged in an array, which is convenient for increasing the fusion of the medicament. Then, when the silt pretreatment medicament adding device is in use, the spraying direction of the medicament in its internal medicament adding and filling device is relatively easy to change, making the spraying angle of the medicament convenient for full fusion with the silt, thereby improving the overall treatment efficiency. After the medicament is sprayed out, it impacts the surface of the baffle 503. The baffle 503 sputters the sprayed medicament, making the medicament and the silt more fused, facilitating the treatment of the silt. The baffle 503 is supported by the support rod 502, and one end of the support rod 502 is connected to the mounting seat 501. The whole is connected and fixed to the inside of the conduit 1 through the mounting seat 501. Then, the silt pretreatment medicament adding device has a device for increasing the mixing property inside, which is convenient for the diffusion of the medicament.
