Abstract
The invention discloses a method for carrying out environment-friendly treatment on a cassava alcohol vinasse liquid. The method comprises the following steps of: (1) fermenting cassava alcohol vinasse in a primary anaerobic pot at 54-58 DEG C through cooling and controlling the temperature; (2) enabling minus sieve liquid to flow through a horizontal flow sedimentation tank and then enter one-stage and two-stage serially-connected air floaters; and continuously dripping polymerized ferrosilicon into the air floaters; (3) enabling the liquid obtained by secondary anaerobic digestion to flow through a vertical flow sedimentation tank and enter three-stage and four-stage serially-connected air floaters; continuously dripping the polymerized ferrosilicon into the air floaters; and (4) enabling plus sieve objects, the air floaters, sedimentation tank sludge and the like of a beveling sieve to enter a sludge collecting tank, filtering by a plate frame, and taking percolate to be subjected to secondary anaerobic treatment. Compared with the prior art, the method has the following beneficial effects that (1) the use amount of a polymerized ferrosilicon coagulant is reduced by 30% under the same treating effect condition; and (2) the coagulation effect is improved by 20% under the same additive amount condition.
Description
Technical field
The invention belongs to the environmental protection treatment technical field, more specifically relate to cassava vinasse as substratum liquid is carried out environment-friendly treatment method.
Background technology
The waste water of Alcohol Production during mainly from distillation fermenting-ripening wine with dregs topping still bottom discharging distillation leftover--the alcohol grain is high concentrated organic wastewater.The every production of Alcohol Production take cassava as raw material 1t alcohol approximately discharges 8-11t alcohol grain.It is acid that cassava vinasse as substratum is, and COD is up to 5～70,000 mg/L, and suspension content is high.Administer route and be mainly anaerobism ten aerobic process, namely B grade anaerobic fermentation (the complete poor anaerobically fermenting of high temperature and middle temperature clear liquid anaerobically fermenting) and SBR aerobic treatment are processed water COD in the following decontaminated water of 300mg/l treatment plant.
The characteristics that complete poor high temperature anaerobic is processed are that need not to remove solid substance be that solid content (SS) is high, the residence time is long but the biogas amount of output is that economic worth is high more to vinasse.The characteristics of middle temperature clear liquid anaerobic treatment are can adopt high efficiency anaerobic reactor (such as UASB, IC) but the solid content of feed liquor is had certain requirement.Therefore treatment process warm clear liquid anaerobic fermentation process from complete poor high-temperature anaerobic fermentation changes over to need to be removed solid substance the SS amount is controlled at certain scope, this is the crux of guaranteeing regulation effect.At present, the technology of employing is mainly: full-distillage anaerobic digestion liquid through Dou screening from, screen overflow filters through sheet frame (or whizzer), screen underflow is processed through settling tank (tank).Filtered liquid and precipitation supernatant liquor enter anaeration in normal temperature behind the air supporting desilt.
The technical problem that above-mentioned prior art exists is as follows:
The principle that air supporting is processed passes into air exactly in waste water, and separate out from water with the micro-bubble form and to become carrier, the pollution substances such as small suspended particle in the waste water are sticked on the bubble, with floating to the water surface on the bubble, form foam one gas, water, particle three-phase mixture, the purpose that reaches separating impurity, purifies liquid waste by collecting foam or scum silica frost.Be mainly used to process in the cassava alcohol waste water by natural subsidence or floating and be difficult to remove relative density close to 1 micro fiber particle and impurity.
Because the intrinsic characteristic of cassava alcohol waste water adopts merely the air flotation technology treatment effect not reach ideal effect therefore usually adopt interpolation medicament such as polymerize aluminum chloride to reach the air supporting removal of impurities except solid effect.How to choose and grasp the air supporting of cassava alcohol waste water process in removal of impurities except solid pharmacy variety and addition, just become air supporting treatment effect and impact to the crux of rear road regulation effect.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, a kind of method of cassava vinasse as substratum liquid being carried out environmental protection treatment is provided.The present invention improves whole regulation effect thereby improved to the solid impurity-eliminating effect of removing of cassava grain stillage waste water by add the polymerization ferro-silicon coagulant in administering link air supporting.
For achieving the above object, the present invention has taked following technical scheme:
A kind of method of cassava vinasse as substratum liquid being carried out environmental protection treatment comprises the steps:
(1) the full grain of cassava alcohol through the cooling temperature control in the one-level anaerobic jar in 54-58 ℃ of bottom fermentation, output biogas is as clean energy, residence time 12-15 days; Digestion fluid (clear liquid COD is 3500-4500mg/l) through 60-100 order Dou screening from.
(2) the lower liquid of sieve enters the air supporting of I and II series winding behind horizontal sedimentation tank, drips continuously the polymerization ferrosilicon in air supporting, adds overall control and is the 0.02-0.06% of the lower liquid weight of sieve, and air supporting fluid effect is: COD3500-4000mg/l, SS1800-2200mg/l; Fluid enters secondary anaerobic reactor (36-45 ℃, residence time 3-5 days).
(3) secondary anaerobic digestion fluid through vertical sedimentation tank enter three, the air supporting of level Four series winding, in air supporting, drip continuously the polymerization ferrosilicon, add overall control and be the 0.02-0.05% of digestion fluid weight.Fluid enters that final fluid COD is below the 300mg/l after the SBR aerobic treatment.
(4) Dou sieve screen overflow and air supporting, settling tank mud etc. enter the collection mud sump, and through Plate Filtration, filtrate enters secondary anaerobic and processes.
Compared with prior art, the present invention has following beneficial effect:
(1) under the equal treatment effect condition, polymerization ferro-silicon coagulant consumption cost descends 30%.
(2) under the equal additive capacity condition, coacervation effect promoting 20%.
Embodiment
The present invention will be further described below in conjunction with specific embodiment.
