Abstract
The present invention relates to a method for processing waste water containing hydroxybenzene by using hyphae of fixed large-scale edible fungi of a cellulose carrier. The method uses the existing edible fungi or strains bred on the basis of the existing strains, which have higher capability for processing phenolic compounds; inoculation is carried out on a culture medium made from cellulose objects with proper nutritional ingredients, a fixed carrier of fixed living hyphae is cultivated, and the carrier can carry out processing for the waste water containing hydroxybenzene. The present invention has the technology that mushroom bodies can be firstly harvested, and then, the waste water is processed by the carrier of the harvested mushroom bodies. The present invention has the advantages of simple and convenient method, little air flow and low cost; the present invention can carry out waste water processing under broad temperature, and fully utilize waste.
Description
The invention belongs to a kind of immobilized cell fermentation technology and utilize the large edible fungus hypha biological treatment to contain the phenolic compound method for waste water.
The biological treatment of phenolic wastewater is present widely used technology, for example activated sludge process.This method is easy and simple to handle, but because the department of microbiology suspended state that uses, so thinning ratio is limited, efficient is not high.
Immobilized cell technology is a new developing technology on traditional suspension cell fermentation basis, and because of the transformation efficiency height, life cycle is long, and cost hangs down and waits and the tool clear superiority.In recent years, immobilized growing cell has been used to Phenol-Containing Wastewater Treatment, and the cell that is fixed mainly is a yeast, as candiyeast; The carrier that is used for fixing mainly is an organic compound; As alginate calcium, polyvinyl alcohol etc.For example, fix on " immobilized microorganism method Research on Phenol Wastewater Treatment " civilian described method of delivering on environmental science 11 the 1st phases of volume of nineteen ninety week.Aforesaid method has 3 main drawbacks:
1. process for fixation bothers, and the solidify material price is more expensive; 2. treating processes must be forced a large amount of ventilations continuously, and energy consumption is bigger; 3. Shi Yi temperature range is limited, generally is lower than 20 ℃, be higher than 35 ℃ then treatment effect obviously descend.
Task of the present invention is to select new types of spawn for use, so that the more easy curing of use has wideer treatment temp, lower processing cost.
Fixed large edible fungus hypha of the present invention is handled the method that contains phenolic compound waste water, the bacterial classification that is adopted comprises that various large edible fungus (for example, flat mushroom, mushroom, straw mushroom ... or the like), the selection principle of its bacterial classification should be the higher bacterial strain of polyphenol oxidase activity; And the bacterial classification that more efficient processing contains the phenolic compound ability that has that on the prior art basis, adopts various technology seed selections.The substratum that is adopted adds the proper nutrition composition as solidified carrier based on the wood chip of cellulose, boll hull etc. and other similar waste, and said solidified carrier can be made column, tabular ... wait other shape.Above-mentioned bacterial classification inoculation is cultured to the above-mentioned substratum promptly becomes suitable immobilization viable bacteria silk after covering with mycelia, preferably treat this mycelia differentiation and results mushroom body after, cultivate again after 1～5 day and use.
Place pending phenolic wastewater with above-mentioned through the solidified carrier after bacterial classification, the mycelium culture, just can handle phenolic wastewater.Because mycelia is linked to be integral body on carrier, so in handling the waste water process, the part of this solidified carrier can be exposed in the air, then can reduce air flow, not even ventilation; This solidified carrier is not exposed in the air, but should suitably ventilate, stir this moment.
Contain phenolic compound waste water in order to make method of the present invention can be suitable for handling in the wide temperature range, under high, medium and low different temperature condition, select the immobilization carrier of the large edible bacterium breeding strain of suitable relevant temperature scope for use.
Adopt the method for Phenol-Containing Wastewater Treatment of the present invention, its treating processes can be batch formula of using in bed formula reaction tank, or criticizes formula continuously, or the mode of successive reaction is carried out.
Employing cellulose carrier of the present invention is edible mushrooms viable bacteria silk Phenol-Containing Wastewater Treatment method fixedly, and following effect and advantage are arranged compared with the prior art:
1. broad application temperature range is because different edible mushroomss has different optimal temperatures, so under different temperature condition, as long as change the solidified carrier of using different edible bacteriums (silk), can handle on a large scale at 5 °～45 ℃; Prior art generally can only be handled under 20 °～35 ℃ conditions.
2. processed waste water contains phenolic compound concentration can be at 1～600ppm, and its pH value can be in the scope of pH5.5～pH10.
3. adopt the cellulose castoff carrier that fixes, its fixing means is simple, and cost is low, especially is used further to handle waste water when mycelia differentiation fruiting and after gathering in the crops the mushroom body, can be at one stroke two must, and further reduce processing cost.
4. in handling the waste water process, be exposed in the air, then can reduce air flow as long as will solidify the part of post or plate; Even ventilation can not saved energy consumption.
5. place phenolic wastewater after for some time uses when solidified carrier, but this cured article monoblock is taken out and as fuel, thereby can avoid polluting for the second time.
Below be example narration the inventive method with the straw mushroom.
Selected straw mushroom bacterial classification inoculation is being added with the proper nutrition composition, diameter is on the cylindrical boll hull substratum of 10cm, under 25 °～40 ℃ temperature, cultivated about 10 days, treat mycelia cover be placed on make under 25 °～35 ℃ its differentiation fruiting, (can repeat to gather in the crops 2 times) cultivated 1～5 day again behind the results mushroom body, make the mycelia activation, then this being solidified post inserts in the pending waste water that contains phenol 1～600ppm in turn, and this curing column top 5～10cm is exposed in the air, wastewater temperature can be at 25 °～45 ℃, pH7～10, and suitable situation feeds an amount of air, stir, or stuffiness, dilution rate is D=0.1～0.2.
