Technical Field

The invention belongs to the field of urine treatment, and particularly relates to a method for treating organic liquid fertilizer of human urine, which utilizes novel lactobacillus QV1 to treat the human urine.

Background

According to the statistics of the World Health Organization (WHO), the human urine accounts for only 1% of the total domestic sewage in the sewage objects treated by the urban sewage treatment sites of various countries, but 80% of nitrogen, 55% of phosphorus and 63% of potassium treated by the urban sewage treatment sites are derived from the human urine. The pollution (eutrophication) of rivers, lakes and seas mainly comes from the increase of nitrogen and phosphorus, so that human urine is one of the main pollution sources of the natural environment.

On the other hand, human urine is an excellent organic fertilizer, and the contents of nitrogen, phosphorus and potassium are respectively 0.5%, 0.13% and 0.19%, and the organic matter is 2%. According to the latest research, human urine is the only quick-acting fertilizer which can replace chemical fertilizers and is beneficial to soil; energy conservation, environmental protection and resource recycling are advocated in modern society. Therefore, the modern human society urgently needs a complete technology which is used for simply, conveniently and quickly collecting human urine, converting the human urine into organic liquid fertilizer and recycling the organic liquid fertilizer for the modern agriculture.

Human urine is derived from waste fluid from blood filtered by kidney; unlike feces produced through the digestive tract, urine contains no parasite eggs, and urine immediately discharged by healthy persons is essentially sterile; human urine is 95% water, 5% soluble substances and inorganic salts, of which about 2% is urea, 1% is sodium chloride, and small amounts of uric acid, hippuric acid, creatinine, oxalic acid, sulfate, nitric acid, xanthine and the taste substances androsterone. Therefore, the urine of normal people is fully filtered by the kidney, is safe and sanitary, can be obtained everywhere and has no raw material cost; the key is to identify simple and low cost means of collection and on-site pretreatment. Although there are reports on the treatment of urine at present, there is no good method.

For example, chinese patent application No. 201510243284.1, published as 2015, 11/11, discloses a method for treating urine from a farm animal, wherein the urine is discharged by feeding the farm animal with water treated with a glass composition. Actually, urine itself has no odor, and is rich in nutrients such as protein, inorganic salts, organic matters and the like, so that bacteria are easy to breed, and urea is decomposed to generate ammonia odor. The method of this patent does not solve the fundamental problem of urine odor. Chinese patent application No. 201510047504.3, application publication No. 2015, 4-29 discloses a method for treating urine. Which comprises the following steps: taking a plurality of raw urine for standby; adding urease to remove urea; adding an internal standard and fixing the volume; adjusting the pH value, adding hydroxylamine hydrochloride, and neutralizing after reaction; extracting, drying and then carrying out derivatization reaction; the retention time calibration is performed. The method disclosed in the patent is used for pretreatment of urine, aims to ensure that the detection in the later period is more accurate, and uses urease, so that the cost is higher, and the method is not suitable for wide application. More importantly, the existing method only treats urine to achieve the purpose of no odor or emission, and the urine, a valuable fertilizer resource, is not recycled.

At present, the market needs a method which can effectively prevent the odor of urine, does not lose or hardly lose effective nutrient components such as nitrogen, phosphorus and potassium in the urine and prepares the nutrient components into organic liquid fertilizer so as to completely recycle the nutrient components.
