Problems solved by technology

Although the high-efficiency clarifier and fiber ball filter are backwashed many times after running for a period of time, the dense filter layer of the high-efficiency clarifier and the fiber balls in the fiber ball filter are still prone to hardening and failure, resulting in black water quality that cannot reach the return water standard

Embodiment 1

[0027] Such as figure 2 , Figure 4 As shown, the reforming device for treating coal-containing wastewater from coal transportation includes a primary sedimentation tank for feeding raw coal slime water. The primary sedimentation tank is connected to the dosing system, and a labyrinth barrier 1 is arranged in the primary sedimentation tank. The sewage in the primary sedimentation tank enters the secondary sedimentation tank after overflowing, and the outlet water of the secondary sedimentation tank enters the fiber ball filter through the lifting pump, and the water outlet of the fiber ball filter is connected with the water inlet of the clear water tank. Connected by a one-way valve, the outlet water of the clear water pool is reused after passing through the clear water pump; the clear water pool is also connected with the backwash pump, and the water outlet of the backwash pump is connected with the backwash water inlet of the fiber ball filter connected, and the backwash...

Embodiment 2

[0038] Such as image 3 , Figure 4 As shown, the reforming device for treating coal-containing wastewater from coal transportation includes a primary sedimentation tank for feeding raw coal slime water. The primary sedimentation tank is connected to the dosing system, and a labyrinth barrier 1 is arranged in the primary sedimentation tank. The sewage of the first-stage sedimentation tank enters the second-stage sedimentation tank after overflowing, and the water outlet of the second-stage sedimentation tank is connected with the water inlet of the third-stage sedimentation tank, and the outlet water of the third-stage sedimentation tank is returned to after passing through the clean water pump. use.

[0039] The dosing system is provided with a coagulant dosing port and / or a flocculant dosing port.

[0040] The coagulant includes PAC, and the flocculant includes PAM.

[0041] An automatic mixing unit is provided in the primary sedimentation tank.

[0042] The automatic mi...

Abstract

The invention discloses a coal-containing wastewater treatment reconstruction device for coal transportation, and belongs to the technical field of wastewater treatment. The device comprises a primarysedimentation tank for introducing raw coal mud water, the primary sedimentation tank is connected with a dosing system, a labyrinth parry is arranged in the primary sedimentation tank, overflowing sewage of the primary sedimentation tank enters a secondary sedimentation tank, effluent water of the secondary sedimentation tank enters a fiber ball filter through an elevator pump, the water outletof the fiber ball filter is connected with the water inlet of a clear water tank through a non-return valve, and effluent water of the clear water tank goes through a clear water pump and then is reused; and the clear water tank is also connected with a backwashing pump, the water outlet of the backwashing pup is connected with the backwashing water inlet of the fiber ball filter, and the backwashing water outlet of the fiber ball filter is connected with the primary sedimentation tank. The coal-containing wastewater treatment reconstruction device has the advantages of simplification of an existing treatment device, reduction of the investment cost, and stability and high efficiency in running.

Description

technical field [0001] The invention relates to a treatment reformation device for coal-contained waste water, which belongs to the technical field of waste water treatment. Background technique [0002] Such as figure 1 As shown, the current coal-contained wastewater treatment device is to use the lifting pump to transport the coal-contained wastewater washed out of the trestle and coal yard of the coal transportation system to the first-level coal sinking tank, and then pass through the first, second and third-level sedimentation tanks step by step. After natural settlement, the waste water is sent to the cyclone reactor and high-efficiency clarifier through the lifting pump, and the dosing system is connected to the inlet main pipe of the cyclone reactor to allow the medicine and wastewater to mix and react evenly. After the water from the high-efficiency clarifier enters the intermediate pool, it enters the fiber ball filter after a second lift, and finally reaches the ...
