Description

A kind of processing method of vegetable-pickling waste water
Technical field
The present invention relates to field of waste water treatment, particularly to the processing method of a kind of vegetable-pickling waste water.
Background technology
Pickle is appetizing food common on China's resident's dining table, and it has inadvisable in the diet of Chinese The status in generation.But substantial amounts of high salt acidic organic wastewater can be produced during vegetable-pickling, if vegetable-pickling waste water is directly arranged Put structure and the nutrition being easily destroyed soil so that soil leanness, the growth of harm animal and plant, the most more and more Cause people's concern to it.Although the Organic substance easily biological-degradable in vegetable-pickling waste water, but the sodium chloride of its middle and high concentration But the growth of microorganism can be produced inhibitory action.
Publication No. CN101586084A, publication date are that the Chinese patent on November 25th, 2009 provides a strain guarantor Hide numbered CGMCC No.3000, vegetable-pickling waste water can be carried out the candidiasis G70 of weak basification (Gandida thaimueangensis) and utilize the method that this bacterial strain carries out weak basification to vegetable-pickling waste water.
Research finds, although this candidiasis G70 can be by the metabolic activity of self by vegetable-pickling waste water Acidity is removed completely, but owing to the speed used time limiting this process of salinity is longer;And the effect of this process and efficiency All Effects of Salinities by pickling waste water are bigger.
Summary of the invention
It is an object of the invention to provide the processing method of a kind of vegetable-pickling waste water, which solve and process at candidiasis The speed of vegetable waste water and effect, by the bigger problem of Effects of Salinity, have quickening waste water treatment efficiency and improve treatment effect Advantage.
The above-mentioned technical purpose of the present invention has the technical scheme that
The processing method of a kind of vegetable-pickling waste water, comprises the steps:
Step 1, takes vegetable-pickling waste water, the float being filtered to remove in vegetable-pickling waste water;
Step 2, the vegetable-pickling waste water that step 1 of learning from else's experience processes, between pH 3.5-4.0 to 10-10.5, carry out pH regulator, adjust The solid separated out is removed in time during joint;
Step 3, the vegetable-pickling waste water that step 2 of learning from else's experience processes, add antagonist, regulate pH to 6-7;
Step 4, takes cultured candidiasis, sprays the micro-water permeable membrane of heatproof at its outer surface, is added to afterwards through step 3 In the vegetable-pickling waste water processed, Aerobic Process for Treatment.
Use said structure, first, the pH of vegetable-pickling waste water be adjusted between 3.5-4.0 to 10-10.5, Change the pH condition of vegetable-pickling waste water, in multiple pH condition, polymorphic type impurity is carried out precipitation process, reduce in waste water Impurity content;Under different pH regulator, system is carried out recrystallization crystallize, the salinity in regulation waste water, makes in waste water Salinity condition be applicable to candidiasis waste water process;
Secondly, having the micro-water permeable membrane of heatproof at candidiasis trypsin method, candidiasis progresses in waste water system by this film, Candidiasis is selected the superior and eliminated the inferior in this process, can improve the disposal ability of candidiasis;This film is to candida mycoderma simultaneously Bacterium plays the effect of protection, and in the waste water entrance film outside film, the candida mycoderma in rear tunicle quickly processes, and the water after process is to film Neighbouring pickling waste water plays certain diluting effect, and the disposal ability of the candida mycoderma near raising film, carries further further The treatment effect of high pickling waste water;
Research proves, the applicable salinity being processed vegetable-pickling waste water by the present processes is 0.5-10.0%, and its treatment effect All effectively improve with efficiency.
More preferably: concretely comprising the following steps of described step 2: the vegetable-pickling waste water that step 1 of learning from else's experience processes, adjust Joint pH to 3.5-4.0 stirring makes it separate out solid, is filtered to remove impurity;First gradually heighten the pH of vegetable-pickling waste water extremely 10-10.5, more gradually turn down the pH to 3.5-4.0 of vegetable-pickling waste water, by 0.5 governing speed regulation of pH/ time, and After regulation pH, stirring makes it separate out solid every time, is filtered to remove impurity.
Use said structure, gradually regulate, the situation that the partial impurities that too fast regulation causes eliminates the most completely can be reduced, Regulate between pH3.5-10.5 simultaneously, the microorganism survival of the fittest originally existed in vegetable-pickling waste water can be improved, make excellent The microorganism of matter enters the waste water in later stage and processes, and improves its waste treatment capacity further;It was verified that when described regulation speed When degree is 0.5 pH/ time, the waste treatment capacity in its later stage can obtain stability contorting, it is adaptable to big production application.
More preferably: in step 2, regulation pH adjusting agent used by pH is selected from K2CO3、KOH、Ca(HCO3)2、Ca(OH)2、HCl、H2CO3
Using said structure, the impurity of introducing not only processes without interference with waste water, moreover it is possible to reduce Na+Suppression to microorganism Effect.
More preferably: described antagonist is selected from K+、Ca2+、Fe3+、Fe2+、Mg2+、Al3+In at least one.
Use said structure, its energy and Na+Effect, reduces Na+Inhibitory action to microorganism;It uses these simultaneously The antagonist of type, its energy and Cl-Effect, reduces salinity and reduces the salinity altercation impact on microbial treatments waste water.
More preferably: described candidiasis is selected from candidiasis G70.
Using said structure, its cellularity is unique, has wider pH growth scope and high organic composite tolerance, It has corresponding salt tolerance.
More preferably: the micro-water permeable membrane of described heatproof includes polyethers, polyolefin copolymers and polyester acid copolymer; And the micro-water permeable membrane of heatproof includes that the weight ratio of polyethers, polyolefin copolymers and polyester acid copolymer is 1: 5-10: 5-10.
Using said structure, triple combination acts on, and has preferable acid-fast alkali-proof temperature tolerance, and three entwines into tool simultaneously There is more areolate micro-water permeable membrane, can supply water and the turnover of a small amount of candidiasis.
Research finds, the weight ratio of described candidiasis and the micro-water permeable membrane of heatproof is 1: 0.5-2, the micro-water permeable membrane pair of heatproof Protection and the facilitation of candidiasis are most suitable.
More preferably: the micro-water permeable membrane of described heatproof also includes adhesive hybrid resin;And described polyethers and compound tree The weight ratio of fat binding agent is 1: 0.1-0.5.
Using said structure, first, micro-for heatproof water permeable membrane and candidiasis are bonded together by adhesive hybrid resin, Both annexations can be improved further;Secondly, the biological activity of candidiasis and the impact of diffusion velocity can be neglected by it Slightly disregard;It addition, micro-permeable and candidiasis the effect of the micro-water permeable membrane of heatproof is not affected by.
More preferably: described spraying uses fluidized bed gas suspension method.
Use said structure, the micro-water permeable membrane of the heatproof outside candidiasis can be made evenly, it is ensured that the micro-water permeable membrane of heatproof Protective effect.
In sum, the method have the advantages that
1. the processing method of a kind of vegetable-pickling waste water of the application of the application is less by the Effects of Salinity of vegetable-pickling waste water, is suitable for In salinity at the vegetable-pickling waste water of 0.5-10.0%, its highly effective, it is adaptable to large-scale production;
2. utilizing the processing method of a kind of vegetable-pickling waste water of the application, run 30 days continuously, CODcr clearance reaches 54%, Its Aerobic Process for Treatment time is short, and treatment effeciency is high.
