Abstract
The invention discloses a method for preparing a nitrogen-conserving active organic fertilizer from food factory waste liquid and animal dung. The method comprises the following steps: mixing the raw materials, and regulating the moisture and the carbon nitrogen ratio; covering the stockpile with a layer of nitrogen-conserving material and carrying out primary fermentation, and in the process, every time when the stockpile is turned, replenishing water according to the requirements, turning the stockpile and covering the stockpile with one layer of nitrogen-conserving material; repeating the process a plurality of times until the ammonia smell is lightened and no irritation is left, then stopping applying the nitrogen-conserving material, and continuing fermenting until the temperature of the stockpile is lower than 45 DEG C; turning the stockpile again, directly replenishing water to the surface layer of the material so that the surface layer is wet by the thickness of 10cm and carrying out secondary fermentation for at least 20 days, thereby obtaining the nitrogen-conserving active organic fertilizer. The method for preparing the nitrogen-conserving active organic fertilizer is used for solving the problems of relatively excessive loss of nitrogen, stink of ammonia gas and the like in the fermentation process of the fertilizer, and meanwhile, is capable of improving the using effect of the fertilizer. The method is a model of combined environmental protection and agriculture.
Description
[technical field]
The present invention relates to a kind of production method of protecting nitrogen type active organic fertilizer, relate in particular to a kind of food factory's waste liquid and fowl and animal excrement of utilizing and prepare the method for protecting nitrogen type active organic fertilizer, belong to agriculture fertile production technical field.
[background technology]
In utilizing at present the process of fowl and animal excrement making fertilizer, tend to because the problem of raw material C/N and technique, cause that the on-the-spot ammonia of fertiliser production is dense, fly disorderly flies, and it is also relatively not high that fertilizer can lose nitrogen element, humic acids content generally, not only affect workman's physical and mental health, also can cause nitrogen loss, workman's resignation, guest to detest the problems such as visit, cause the great attention of manufacturer.
The more current waste molasses in sugar refinery and the waste yeast liquid of yeast factory etc., its humic acids and total nutrient are higher, are the good raw material of producing fertilizer.Because these humic acidss originally just have higher activity (this just can be used as the main raw material of producing containing fertilizer such as humic acid water-soluble fertilizer, organic water-soluble fertilizers), make an addition in organic fertilizer production process, can produce high reactivity fertilizer in theory.Food factory's waste liquid mixes mutually with guarantor's nitrogen material, also has the nutrients such as part nitrogen, potassium to be adsorbed by food factory's waste liquid simultaneously, to reducing the loss of fertilizer nutrient in soil, has good prophylactic effect.But it exists equally, and production scene ammonia is dense, fly disorderly flies, and fertilizer can lose also relative not high problem of nitrogen element, humic acids content generally.
How the useless raw material of manufacturer being processed with improvement soil and to be combined, is current environmental protection and the agriculture problem in conjunction with being devoted to.
[summary of the invention]
The object of the invention is, in order to overcome the defect of prior art, provides nitrogen loss in a kind of minimizing fermenting process, solves ammonia smell pungent, and utilize food factory's waste liquid and the fowl and animal excrement that improve fertilizer activity prepares the method for guarantor's nitrogen type active organic fertilizer.
The present invention for achieving the above object, by the following technical solutions:
Utilize food factory's waste liquid and fowl and animal excrement to prepare a method of protecting nitrogen type active organic fertilizer, it is characterized in that comprising following concrete steps:
A, raw material is mixed after, regulate moisture to 50～70%, carbon-nitrogen ratio 15～25:1, windrow is prepared fermentation;
B, at windrow surface coverage one deck, protect nitrogen material and carry out one time fermentation, in one time fermentation process, after each windrow turning, if the overall moisture content of windrow lower than 45% time, moisturizing turning again after each windrow turning, cover one deck and protect nitrogen material on windrow;
C, repeatedly to the stirring of windrow, moisturizing and turning, until that ammonia taste subtracts is light to there is no pungency, without covering and protect nitrogen material again, continue to ferment to windrow temperature lower than 45 ℃, again, after turning, directly in the moisturizing of material top layer, make its top layer have 10cm thickness moistening;
D, moistening windrow is carried out to Secondary Fermentation, time remaining at least 20 days, must protect nitrogen type active organic fertilizer.
In step a of the present invention, with tap water or well water, regulate the moisture that mixes rear raw material, but the river that can not enter river with seawater or the inwelling of saliferous, or similar water, in like manner, while diluting food factory containing humic acids waste liquid, be also with tap water or well water dilution; With a kind of nitrogen content that regulates in urea, volatile salt and bicarbonate of ammonia, by organic content, be greater than the carbon content that 70% rice bran, mushroom residue or wooden chaff regulate windrow, heightening or turning down of nitrogen element and carbon, can make the carbon-nitrogen ratio of windrow between 15～25:1.
In addition, also will consider the total nutrient of mixture is how many, guarantee that the fertilizer that ferments out meets industry standard, be clearly organic >=45% in fertilizer industry standard NY525-2012, total nutrient >=5%.
Guarantor's nitrogen material in the present invention is including, but not limited to one or more in zeolite powder, sepiolite and activated carbon, and the fineness of described guarantor's nitrogen material is 30～150 orders, and moisture is not higher than 10%, and each overlay capacity is 0.5～5Kg/ cube of windrow.
In one time fermentation process of the present invention, the raw material that after each windrow stirs, moisturizing is used is: food factory is diluted with water to the moisturizing liquid of moisture 60～80% containing humic acids waste liquid, this water is not limited to tap water or well water etc., but the river that can not enter river with seawater or the inwelling of saliferous, or similar water.Moisturizing liquid just modulates before each windrow stirs, turning again after each limit moisturizing limit turning or moisturizing, and then covering one deck guarantor nitrogen material, so-called one time fermentation is not one time fermentation only, and refers to fertilizer Secondary Fermentation (ageing) fermenting process before.
In the present invention, in one time fermentation process, be not to stir windrow all to want moisturizing, be moisture just moisturizing lower than 45% time after windrow stirs at every turn, and each windrow moisturizing is adjusted to the overall moisture 45～55% of windrow, take 50% as preferred.Moisture content in the present invention is mass percentage content.
In Secondary Fermentation process of the present invention, turning in every 5 days once, after each turning, compacting material top layer once a little, the Secondary Fermentation time, the longer the better, but consider from economic benefit, is generally 20 days.
The present invention compared with prior art, has following advantage:
By the present invention, prepare in the process of fertilizer, solved the relative excessive loss of nitrogen in fertilizer fermenting process, the problem of the breath malodor such as ammonia, because added the waste liquid containing humic acids, humic acids content is high simultaneously, on the other hand because nitrogen loss is few, during use, the nitrogen content that enters soil is high, so improved the result of use of fertilizer, has good social benefit.
The present invention provides the useless raw material of producer to process and improve the question synthesis such as soil manufacturer's waste gas generation, food factory's waste liquid (refuse of keeping under strict control), some fertilizer raw materials and solves, be the typical case of environmental protection and agriculture combination.
