Description
Technical field
The present invention relates to fertilizer preparation technology field, particularly relate to a kind of utilize monosodium glutamate waste liquid to produce high fertilizer efficiency fertilizer method and product.
Background technology
Monosodium glutamate waste liquid is mainly derived from fermented gournet powder liquid and extracts the L-glutamic acid stage.According to statistics, produce 1 ton of monosodium glutamate and will discharge high-concentration waste water about 20 tons.And monosodium glutamate waste liquid to have COD high, BOD is high, and thalline content is high, and sulfate radical content is high, the feature that ammonia-nitrogen content is high and pH value is low " five high low ", once entering river, produces severe contamination to water body, destruction ecotope, and is that one of resource is wasted greatly.The utilization of monosodium glutamate waste liquid comprises extraction yeastex, produces fodder yeast, fertilizer etc.; At present, domestic to the direct spray pelleting process of the many employings of producing fertilizer with gourmet powder waste liquor, there is evaporation in its production process and dry water consumption mass energy, the defect that cost is high; Simultaneously the monosodium glutamate waste liquid fertilizer organic content of producing through direct spray granulating is low, cannot reach national fertilizer standard.
Summary of the invention
One of the object of the invention is to provide a kind of method utilizing monosodium glutamate waste liquid to produce high fertilizer efficiency fertilizer.
The technical scheme realizing the object of the invention one is: a kind of method utilizing monosodium glutamate waste liquid to produce high fertilizer efficiency fertilizer, it comprises batch mixing, fermentation, screening pulverizing and finished product packing step, and described batch mixing step is: by monosodium glutamate waste liquid, husk chaff and chicken manure ash in (7 ~ 3): (2 ~ 4): (1 ~ 2) ratio mixes, is stacked to fermentation materials.
In order to better technique effect, the method that the present invention utilizes monosodium glutamate waste liquid to produce high fertilizer efficiency fertilizer can also do following improvement:
1, described fermenting process is divided into one time fermentation and Secondary Fermentation; Be down to less than 50 DEG C when fermentation materials temperature no longer to raise, when test in laboratory moisture is down to 40% ~ 45%, one time fermentation terminates; When fermentation materials moisture is down to less than 30%, temperature is close to normal temperature and no longer go up, and during without acid smell, Secondary Fermentation terminates; The bacillus acidocldarius of spray concentration 200,000,000/more than ml before described one time fermentation, the yeast of spray concentration 200,000,000/more than ml in Secondary Fermentation process.One time fermentation stage windrow temperature is high, oxygen requirement large, and select high temperature resistant, aerobic bacillus acidocldarius to be zymophyte, Secondary Fermentation stage temperature of charge is low, and oxygen requirement is less, selects middle psychrophile yeast to be zymophyte; Adding bacterium by rationally arranging stepwise fermentation segmentation, improve the quality of material fermentation speed and fertilizer.
2, described bacillus acidocldarius and yeast consumption are 0.5 ‰ of fermentation materials weight; Improve fermenting speed but production cost is unlikely too large again, if will improve production cost higher than 0.5 ‰ of fermentation materials weight.
3, in described batch mixing step, the optimum proportioning of monosodium glutamate waste liquid, husk chaff and chicken manure ash is (6 ~ 5): (3 ~ 4): (1 ~ 2), by this mix proportion scheme fermenting mixture material moisture 50% ~ 55%, pH value 6-7, C/N is than 18 ~ 22, the good dissolved oxygen amount of material permeability is high, be comparatively suitable for fermentation, can fermentation time be shortened, save production cost.
4, after described batch mixing step, fragmentation is carried out to mixture, make raw meal particle size be less than below 10mm, moisture distribution is even.Diminished by broken material granularity, moisture distribution is even, be beneficial to fermentation, shortening fermentation period.
5, in the fertilizer that obtains of screening pulverising step, directly add chicken manure ash and the oxalic acid of different ratios, regulate N, P, K ratio in fertilizer and pH value to produce various speciality fertilizers on commercial crops.
Two of object of the present invention is to provide a kind of low cost high fertilizer efficiency organic fertilizer, and it is obtained by the preparation method of goal of the invention one.
Beneficial effect of the present invention is as follows:
1, the present invention select water content is low, pH value is higher chicken manure ash for auxiliary material and the monosodium glutamate waste liquid that water content is high, pH value is lower mixed, moisture in quick adjustment monosodium glutamate waste liquid and pH value, save the energy consumption of evaporation and oven dry moisture, reduce production cost, simultaneously, pH regulator can accelerate material fermentation to neutral left and right.
2, use containing organic higher husk chaff in preparation technology is fermentation auxiliary material simultaneously, organic content in effective raising target fertilizer, overcome the fertilizer organic content that Gourmet Powder Factory's tankage tail washings produces through direct spray granulating low, the defect of national fertilizer standard can not be reached.
2, chicken manure ash P, K content is high, by adding certain proportion chicken manure ash and oxalic acid in fertilizer finished product in proportion, conveniently can produce the special fertilizer of different N, P, K content, meet different planting soil, different crops and different growth and development stage thereof the different demands to fertilizer, produce various fertilizer special for organic, achieve the target of balance fertilizing.Organic fertilizer product N, P, K ratio overcoming domestic production is fixed, and is difficult to the shortcoming that demand adjusts or Setup Cost is high according to Different Crop.
3, fertilizer N, P, K total nutrient content of producing of preparation method of the present invention is up to more than 13%, and use on organic farm products is produced, be equivalent to the result of use of organic and inorganic fertilizer, effect of increasing production is obvious.
The compound organic and inorganic fertilizer that a small amount of inorganic fertilizer carrys out production low cost is added in the fertilizer that 4, preparation method of the present invention can also be utilized to produce.
