Embodiment 1

[0026] like figure 1 As shown, the present embodiment provides a process for the treatment of waste water from cigarette factories, which is characterized in that it includes the following steps:

[0027] Step 1. The workshop wastewater first passes through the mechanical grille to remove the coarse floating objects, and then flows into the sump by itself;

[0028] Step 2. The waste water in the sump is pumped by the lifting pump to the curved sieve for filtration, and the fine debris and other suspended matter in the waste water are removed. When the waste water in the workshop is normal, go directly to step 4. When the waste water in the workshop is abnormal, go to step 3;

[0029] Step 3. After the wastewater is filtered by the curved screen, it is switched to the accident pool for storage (if the water collection lift pump fails, the workshop wastewater is directly switched to the accident pool for storage). After the system is stable, the small flow of the accident wastew...

Embodiment 2

[0033] This embodiment is further optimized on the basis of embodiment 1, specifically:

[0034] In step 5, the advanced treatment system consists of an ozone contact tank, a Fenton oxidation tank, a three-settling tank, and an active sand filter. The use of the advanced treatment system is as follows:

[0035] a. When the wastewater treated by the secondary sedimentation tank does not need Fenton oxidation treatment, it will reach the standard of acceptance after being decolorized by the ozone in the ozone contact tank, and then enter the municipal sewage treatment plant for further treatment.

[0036] b. If it is necessary to meet the first-class A standard in the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB18918-2002), the wastewater treated in step a needs to be treated with Fenton oxidation. At this time, the effluent from the ozone contact pool enters After the Fenton oxidation tank, the refractory organic matter in the wastewater is oxidatively ...

Embodiment 3

[0038] This embodiment is further optimized on the basis of embodiment 1 or 2, specifically:

[0039] In step 5, the biogas produced by the IC anaerobic reactor is sent to the gas cabinet for storage, and then sent to the power center boiler for combustion and utilization after dehydration and desulfurization (when not in use, it is burned by a torch); the anaerobic sludge of the IC anaerobic reactor It enters the anaerobic sludge tank for storage (it can be sold outside or supplemented when it is abnormal).

[0040]The residue from the curved screen and the scum from the air flotation machine enter the sieving tank, and then pumped to the sludge thickening tank; the sludge from the primary settling tank, the remaining sludge from the secondary settling tank, and the sludge from the tertiary settling tank are pumped to the sludge thickening tank , concentrated and then pumped to the sludge conditioning tank; the conditioned sludge is pumped to the sludge dehydrator for treatme...

Abstract

The invention discloses a tobacco factory sheet wastewater treatment process, which relates to the technical field of sewage treatment, and comprises the following main steps: mechanical grid treatment, sieve bend, coagulation reaction tank, primary sedimentation tank, air floatation machine treatment, pre-acidification tank treatment, IC anaerobic reactor treatment, A / O biochemical tank treatment, secondary sedimentation tank treatment and advanced treatment system. The invention can well solve the problems of low treatment efficiency, backward technology, high operation cost, easy standard exceeding, poor stability, high management difficulty and the like in the existing treatment process, and ensures that the effluent quality reaches the standard.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, and more specifically relates to the technical field of waste water treatment process of tobacco factory flakes. Background technique [0002] The papermaking method is used to produce tobacco flakes, which are then shredded and added to cigarettes, so that wastes such as tobacco powder and tobacco stems in cigarette production can be fully utilized. It has been widely adopted abroad, and large-scale production has also been formed in many places in my country. Tobacco flake waste water produced by the papermaking method has complex components, high pollutant concentration, a large amount of toxic substances, high chroma, high suspended solids, and oily substances, making it extremely difficult to treat. [0003] After publication, it is "CN106186569A", and the patent title is "a resource-based treatment system and method for tobacco flake sewage", which discloses the following content: ...
