Problems solved by technology
The traditional treatment process can only remove larger solid particles and some suspended solids, and cannot remove a large number of fine-grained suspended solids and chroma in wastewater. Therefore, new technologies and new technologies for efficient treatment of fine-particle wastewater have been developed. Craftsmanship matters

Embodiment 1
[0053] See attached figure 1 And attached figure 2 , the embodiment of the present invention discloses an integrated multi-effect clarification system for treating wastewater stored in a sump 1; including: a lifting pump 2, a flocculation reaction tank 3, a flocculation dosing tank 4, and a multi-effect clarification tank 5 and dehydrator 6;
[0054] One end of the lift pump 2 communicates with the sump 1;
[0055] The waste water outlet of the flocculation reaction tank 3 is located at the bottom thereof, and communicates with the other end of the lift pump 2; the top of the flocculation reaction tank 3 is equipped with an axial flow mixer 7 inserted into it;
[0056] The flocculation dosing tank 4 communicates with the flocculation reaction tank 3 through a pipeline, and is used to add flocculant and / or coagulant to the flocculation reaction tank 3;
[0057] The side wall of the multi-effect clarifier 5 is fixed to the side wall of the flocculation reaction tank 3, and t...
Embodiment 2
[0067] See attached figure 1 and figure 2 , this embodiment discloses an integrated multi-effect clarification method, comprising the following steps:
[0068] S1. The waste water in the sump 1 is input into the flocculation reaction tank 3 through the waste water outlet 31 through the lifting pump 2, and the axial flow mixer 7 is turned on, and flocculants and / or coagulants are added at the same time;
[0069] S2. Turn on the hydrocyclone 11 and the mud scraper 9, so that the sedimentation water entering the multi-effect clarifier 5 is discharged into the dehydrator 6, and the filtrate of the dehydrator 6 is returned to the sump 1, and the top passes through the inclined plate group 8 The clear water filtered again is discharged through the clear water outlet 52 .
[0070] In order to further optimize the above-mentioned technical solution, in S1, fine sand and / or magnetic powder-based dense media carriers are added.
[0071] The concrete principle of this embodiment is: ...

Abstract
The invention discloses an integrated multi-effect clarification system and a clarification method thereof. The integrated multi-effect clarification system is used for treating wastewater stored in awater collecting tank. The system comprises a lifting pump, a flocculation reaction tank, a flocculation dosing tank, a multi-effect clarification tank and a dehydrator. The clarification method comprises following steps: inputting wastewater in the water collecting tank into the flocculation reaction tank through a wastewater inlet by using the lifting pump, starting an axial flow stirrer, and adding a flocculating agent and/or a coagulant at the same time; starting a hydrocyclone and a mud scraper, so that precipitation water in the multi-effect clarification tank is discharged into the dehydrator and flows back to the water collecting tank after filtering in the dehydrator, and clear water filtered again through an inclined plate group at the top is discharged through a clear water discharge port. According to the system, various technologies beneficial to solid-liquid separation, such as chemical flocculation, mechanical stirring, loading precipitation and inclined tube separation, are highly integrated, high-speed and compact effluent of the multi-effect clarification system is kept, the effluent quality is good, and the multi-effect clarification system has the advantages ofhigh impact resistance and running cost saving, and the flexibility of operation and running is improved.
Description
technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an integrated multi-effect clarification system and a clarification method thereof. Background technique [0002] Bleeding water, flushing water, dust suppression water and rainwater precipitation produced during the overshoot of iron ore storage and transportation are the main sources of iron ore storage and transportation wastewater. Wastewater contains a large amount of suspended solids and high chroma. According to the actual operation experience of the project, the concentration of suspended solids in wastewater can be as high as 3000mg / l, and the chroma can be as high as 500 or more. This part of wastewater cannot be discharged directly, nor can it be directly recycled, and needs to be properly treated to meet the water quality requirements for recycling. In the same way, some other mine wastewater, mine water, coal-containing wastewater, and other similar ind...
