Description
The present invention is a technology with the biological method purification high concentrated organic wastewater, is specially adapted to handle aquatic products processing wastewater and methanol rectified raffinate.
Aquatic products processing wastewater refers to washing water and the wash-down water of fishery products in the course of processing based on fish products.Contain pollutents such as fish scale, internal organ, silt in the waste water, belong to high concentrated organic wastewater.Mostly adopt aerobic both at home and abroad or technology such as anaerobic-aerobic or anaerobic-aerobic-denitrogenation are handled.Handle as single aerobic technology (table exposes to the sun or oxidation ditch) that adopts, water outlet can not reach the CODcr＜100mg/l value of " national composite wastewater emission standard " GB8978-88 regulation, NH-N＜15mg/l value, no matter Carrosel device with oxidation ditch or Eimo company, all more shallow because of the degree of depth of ditch or groove, having relatively high expectations of oxygen in water, watt consumption are also high.If employing anaerobic-aerobic or anaerobic-aerobic-denitride technology (see " effect of adding saponin in the activated sludge process ", PPM, 1989,20(4), Japan; " from waste water, remove denitrification and phosphorus simultaneously ", Yosui to Haisui, 1988,30(12), Japan), then, need implement technology, complex structure step by step because of aerobic bacteria can not directly contact with anerobe, the operational administrative difficulty also must add pharmaceutical chemicals sometimes, causes cost greatly to improve.
The novel process and the equipment that the object of the present invention is to provide a kind of high concentrated organic wastewater to handle.Oxidation ditch and Carrosel device are being done on the substantive improved basis, invented and in same device, carried out the aerobic-oxygen-anaerobic treatment process of holding concurrently simultaneously, and this device called after CTB groove (English of China Textile University's biochemical treatment apparatus is called for short), this is aerobic-oxygen of holding concurrently-detest in the nitrogen biochemical device, finish purification to high concentrated organic wastewater.
The invention provides a kind of purifying method of high concentrated organic wastewater, it is characterized in that the waste water that contains CODcr 1000-3000mg/l, BOD5 500-1500mg/l, TN500-800mg/l enters the aerobic-oxygen-anaerobic biological device of holding concurrently, its mesexine is that aerobic layer, middle level are anaerobic layer for the oxygen layer of holding concurrently, lower floor, waste water is stirred in this device, oxygenation, plug-flow be to outlet, is purified water through precipitate and separate.What obtain purifies waste water, CODcr＜80mg/l, BOD5＜10mg/l NH
3-N＜5mg/l.
Be used for the aerobic-oxygen-anaerobic biological device of holding concurrently of the inventive method, comprise inversed umbrella type impeller, wide road formula reactive tank, it is characterized in that the ratio D of impeller diameter D, groove width B, groove depth H: B: H=1: 2.04: 1.34, groove depth H was a 2.6-3.4 rice.
The inventive method is combined in aerobic, anaerobism, three processes of oxygen of holding concurrently in the same system and carries out, itrogenous organic substance at aerobic zone carries out ammonification, nitrosification, nitrification, in anoxic and anaerobic district, carry out denitrification, the meta-bolites of aerobic layer and anaerobic layer is utilized each other, and do not need dosing, and energy and PH self-poise, energy consumption reduces about 25%.Its chemical reaction is as follows:
(1) organic oxidation
(2) synthetic cell material
(3) ammonia oxidation
Oxidation 1kgNH
3-N needs 3.4kg oxygen, and the reaction result pH value descends, and has consumed mixed solution alkali degree, and pH value can be regulated automatically.
NO
- 2-N continues oxidation
(4) denitrification
The inventive method is owing to as above chain reaction, and surplus sludge volume is about 1/60～1/75 of a conventional activated sludge amount, has alleviated the sludge treatment burden.
The present invention carries out significant improvement to the Carrsel device, with D: B: H changed 1: 2.04: 1.34 into by 1: 2.5: 1.2, that is B: H changes 1.48 into from 2.08, the circulation groove area dwindles 28.8%, groove depth is increased to 2.6-3.4 rice, make system form upper strata aerobic layer (under water about 0～1.5 meter), lower floor's anaerobic layer (under water below 2 meters), and interconnect by middle double oxygen layer (under water about 1.5 meters).Because aerobic, the mutual synergy of oxygen, three kinds of Pseudomonas of anaerobism of holding concurrently, make the purification of high concentrated organic wastewater reach very high-level efficiency, during the treat fish processing waste water, present method and anaerobic-aerobic-denitrogenation comparative result sees Table 1, when handling methanol rectified raffinate, present method and other patented method comparative result see Table 2.
Apparatus of the present invention are pulling flow type and hybrid both combinations fully, and load can withstand shocks; And owing to aerobic, the oxygen of holding concurrently, three of anaerobism are reflected in the same device and finish, compact construction, power consumption is low, convenient operation and management.
Accompanying drawing is used to describe main flow process proposed by the invention, fishery products waste water 1 is by grid 2, remove pollutents such as fish scale, enter hold concurrently the oxygen equalizing tank 3 stabilizing water quality water yields and preliminary degraded, then through the inlet 4(1) at inversed umbrella type impeller 4(2) and promotion under enter CTB groove 4, and at wide road formula groove 4(3) in circulate reaction after outlet 4(4) enter settling tank 5, the upper strata purifies clear water 6 and discharges, small portion mud 7 is back to the most of mud 8 of CTB groove and enters concentration basin 9 dehydrations.
Enumerate below and implement object lesson of the present invention, the present invention is described, but is not a kind of restriction of the present invention.
Example 1 certain aquatic products processing wastewater through this flow processing, the results are shown in Table 3.
Example 2 certain methyl alcohol distillation residual liquid are gone into apparatus of the present invention and are handled after pre-treatment, the results are shown in Table 4.
