Problems solved by technology

However, due to the particularity of tobacco sewage, in the process of tobacco sewage treatment, the sludge activity is poor, and the bacteria are difficult to cultivate and survive, resulting in poor and unstable effluent quality of the treatment system, and it is difficult to meet the discharge standards

Embodiment 1

[0031] The cultivation method of tobacco sewage flora comprises the following steps:

[0032] Inoculation: Sludge is used for initial inoculation, and biochemical bacteria agents mainly containing Arthrobacter and Pseudomonas are added to expand and strengthen the cultivation. The sludge is also used as a carrier of bacteria.

[0033] Dosing sludge: inject a certain amount of clear water and tobacco sewage to be treated into the biochemical pool, pour the inoculated sludge into the biochemical pool, the amount of sludge added is 0.6% (vt) of the effective volume of the biochemical pool, add water and stir Uniform, adjusted to 80% (vt) water content in the pool, forming uniform activated sludge;

[0034] Add culture material, nitrogen source, phosphorus source: Add culture material with glucose as the main component, control the concentration of COD in the biochemical pool to be about 300mg / L; then press m(BOD5):m(N):m(P)= 100:5:1, add ordinary calcium superphosphate (hereinaf...

[0045] The cultivation method of tobacco sewage flora comprises the following steps:

[0046] Inoculation: Sludge is used for initial inoculation, and the sludge is also used as a carrier of bacteria, and biochemical bacteria agents mainly containing Arthrobacter and Pseudomonas are added to expand and strengthen the cultivation.

[0047] Dosing sludge: inject a certain amount of clear water and tobacco sewage to be treated into the biochemical pool, pour the inoculated sludge into the biochemical pool, the amount of sludge added is 0.5% (vt) of the effective volume of the biochemical pool, add water and stir Uniform, adjusted to 70% (vt) water content in the pool, forming uniform activated sludge;

[0048] Add culture material, nitrogen source, and phosphorus source: Add culture material with glucose as the main component, control the concentration of COD in the biochemical pool to 250mg / L; then press m(BOD5):m(N):m(P)=90 :4:1, adding common calcium superphosphate (hereinaft...

Abstract

The invention relates to a cultivation method for tobacco sewage flora, and belongs to the technical field of tobacco sewage treatment. The cultivation method comprises the following steps of: carrying out inoculation through domestic sewage treatment sludge; carrying out flora cultivation through the ways of the adding of the sludge, the adding of cultivation materials, a nitrogen source and a phosphorus source, aeration without water change, batch charging again and discharging biochemical metabolism, and forming a great quantity of effective active sludge zoogloeae to realize flora stabilization; and after the flora is stable, gradually increasing a sludge treatment load to realize the industrially stable and continuous treatment of the tobacco sewage. By use of the cultivation method,the stable and up-to-standard treatment of the tobacco sewage can be realized, COD (Chemical Oxygen Demand), BOD5 (Biochemical Oxygen Demand), ammonia nitrogen, LAS (Linear Alkylbenzene Sulfonate), chromaticity, dissolved solids and the like in the tobacco sewage can be effectively degraded, and reutilization after the tobacco sewage is subjected to biological treatment is realized.

Description

technical field [0001] The invention belongs to the technical field of tobacco sewage treatment, and in particular relates to a method for cultivating bacteria in tobacco sewage. Background technique [0002] The biological treatment of wastewater is an environmentally friendly and low-input treatment method, which has been widely used in domestic sewage treatment. Tobacco wastewater is mainly composed of stem washing wastewater, workshop floor cleaning wastewater, glue vat cleaning wastewater, and boiler effluent, with less nutrients, and the nicotine (nicotine) in the stem washing wastewater and the surfactant in the workshop floor cleaning wastewater Toxic and harmful components such as colloids in the waste water from cleaning the glue tank and insecticides mixed into the waste water during regular insecticide in the workshop will have a great impact on the survival and growth of the bacterial flora and the operation of the membrane. [0003] At present, a variety of me...
