Description

Excrement, excrement urine and urine treatment liquid, preparation process and application thereof

Technical Field

The invention belongs to the technical field of bio-organic fertilizers, and particularly relates to a treatment liquid for excrement, excrement and urine, a preparation process and application thereof.

Background

At present, in the strategic plan of promoting the sustainable development of green agriculture, china keeps ecological civilization and strives to build modernization of harmonious symbiosis between people and nature, and excrement and urine are treated by a septic tank, directly discharged to a municipal sewage network and then conveyed to a sewage treatment plant for harmless treatment. The sewage which enters a sewage plant and is treated to reach the standard or not to reach the standard is directly discharged to rivers, lakes and seas to cause eutrophication of water bodies, so that microorganisms and aquatic plants in the rivers are excessively propagated to consume a large amount of oxygen, ecological balance is destroyed, and the water quality of the rivers, lakes and seas is greatly reduced.

At present, a great amount of chemical fertilizers are used in agricultural production, so that the tradition of returning excrement and urine for thousands of years is changed, and the source excrement and urine is a beneficial resource for improving the yield and quality of crops, and becomes a pollution source for damaging the environment.

The struggle goal of farming is to increase the amount of fertilizer and pesticide used to zero. The method has to be vigorously popularized, and the feces and urine treated by biochemical treatment are treated into organic fertilizer to be returned to the field, so that the pollution source of the feces and urine is thoroughly changed into useful resources. For many years, the method for preparing the organic fertilizer from the livestock manure and urine in the research and development field generally adopts a methane tank or a biological enzyme decomposition process. For example, patent document CN 103304286A discloses a process for producing organic fertilizer in dairy farm, which comprises the following main steps: pre-anaerobic fermentation of cow dung and urine; carrying out dry-wet separation on the cow dung urine; sending the wastewater into a methane tank for treatment; the dry cow dung, the biogas slurry, the chicken manure, the microbial agent and the straw powder are mixed according to the weight ratio of 6.5:1:1:0.0000105:1.5, evenly mixing; placing the mixture into a fermentation tank for anaerobic fermentation; performing secondary fermentation; obtaining an organic fertilizer; by adopting the organic fertilizer production process provided by the technical scheme of the invention, the cow dung and urine can be changed into the organic fertilizer so as to solve the pollution of the organic fertilizer. Patent document with application publication number CN 103232148A discloses a method and device for converting human excrement and urine in rural schools into environment-friendly energy and organic fertilizer, which is mainly technically characterized in that: the sewage pump is used for sucking the excrement in the excrement-urine pool of the rural toilet to the tower type methane tank to generate methane for people to use, and then the self gravity of the fermented excrement which becomes the organic environment-friendly fertilizer is used for discharging the organic environment-friendly fertilizer in the tower type methane tank by utilizing the characteristic that the tower type methane tank is higher than the ground.

Human feces contained about 1% nitrogen (mainly protein nitrogen), 0.5% phosphorus (calculated as phosphorus pentoxide) and 0.4% potassium (calculated as potassium oxide). Human urine contains about 0.5% nitrogen (mainly urea), 0.1% phosphorus and 0.2% potassium. Farmyard manure needs to be applied after being decomposed. Human excrement and urine are equivalent to the excrement of livestock and poultry, and belong to farmyard manure. Since human excrement contains a large amount of germs, worm eggs and other harmful substances, if the human excrement is not subjected to harmless treatment, soil, air, water sources and crops can be polluted, diseases can be further spread, and serious harm is brought to the health of people, livestock and poultry, so that the human excrement and the urine can be applied only by the harmless treatment, wherein high-temperature composting is one treatment mode. Should be shaded and covered during the decomposition process, and not be mixed with alkaline substances such as plant ash, lime and the like, so as to prevent the loss of ammonia. Soil is also often mixed with the soil and piled up to form soil manure. Compared with chemical fertilizer, human excrement has the advantages of wide source, complete nutrients, fast and lasting fertilizer effect, capacity of improving soil, low cost, etc. and may be used as additional fertilizer and base fertilizer. The manure is a good natural resource, and the condition that the soil is not manure is equal to blind wild and one flower is grain and is taken as a house by the manure is adopted. Traditional agriculture has demonstrated this. However, the traditional fertilizer retting method has low resource utilization rate and high labor cost. Although efforts have been made for a long time to explore how to convert sources of fecal and urine contamination into useful fertilizer resources, favorable effects have been shown. The current excrement and urine of handling the animal mainly solves the peripheral environmental pollution problem of breeding, and some three tons of animal fermented fertilizer in one mu of land, the cost is very high, can't promote. The current situation of a fecaluria pollution source cannot be changed because the recycling of the fecaluria organic fertilizer cannot be realized because the production chain of collecting fecaluria, concentrating and preparing the organic fertilizer in cities is difficult to form.
