Novel method for innocent treatment and utilization of dead livestock and poultry

The invention discloses a novel method of the harmless treatment and utilization of livestock and poultry which died of disease according to the steps as follows: firstly, various kinds of the animal bodies of the livestock and the poultry which died of disease are collected; secondly, the animal bodies are crushed; thirdly, the crushed animal bodies are sterilized under high temperature and highpressure and separated for filtering, the material of oil and fat flows into a cooling pool, and the material of hair and bone is dried; fourthly, the material of hair and bone after drying is carbonized; fifthly, the material of oil and fat after cooling is added with catalyst, high-efficiency compound microorganism, trash, organic wastewater and sludge; sixthly, the mixed organic material is put into an anaerobic tower to be fermented, and then biogas, biogas slurry and biogas slag are processed for three-phase separation; seventhly, the biogas is used for burning and generating electricity; eighthly, the biogas slurry inside a fertilizer storing pool is used as farmland fertilizer; ninthly, the biogas slag is added with the high-efficiency compound microorganism and the catalyst for secondary ferment; tenthly, the material after the secondary ferment is made into agricultural high-efficiency organic fertilizer. The invention solves the problem of the environmental pollution caused by the livestock and poultry which died of disease and change the waste livestock and poultry which died of disease into valuables.

Organic recycling with metal addition

The invention is directed to methods for producing a granular nitrogen fertilizer from an organic material comprising adding a metallic salt to said organic material to form a slurry. Preferably the organic material comprises dewatered biosolids and contains water from a scrubber. Metallic salts that can be used comprise a salt of iron, zinc, or a mixture thereof. Preferred iron salts comprises ferric sulfate or ferric oxide, and preferred zinc salts comprises zinc sulfate or zinc oxide. Preferably, the metallic salt is mixed with an acid such as sulfuric acid to form an acidified metal salt. Slurry pH ranges from approximately 2-2.5. The acidified metal salt is added to the organic material in sufficient quantity to lower viscosity of the slurry such that the resulting fluid does not hinder fluid flow during operation. When the metallic salt comprises acidified ferric sulfate or ferrous sulfate, sufficient iron can be present to produce a fertilizer product with 0.1 weight percent to 10 weight percent iron sulfate calculated on a dry weight basis. The invention is also directed to fertilizer products made by the methods of the invention. Preferred products are granules and the metallic salt increases product hardness. Fertilizer granules preferably contain metal that is bioavailable to a plant when used as a fertilizer. Solubility of the metal of the product in water is enhanced, and the product is low staining.

Stationary type organic material fermentation machine and fermentation technology thereof

The invention relates to a stationary type organic fertilizer fermentation machine. The stationary type organic fertilizer fermentation machine comprises a substrate, a fermenter, a motor, an electric cabinet, an air purifier and microwave electromagnetic heaters; the two ends of the fermenter are fixedly erected on the substrate; the motor is electrically connected with the electric cabinet; a rotating shaft is arranged on the motor; the rotating shaft is a hollow pipeline and is provided with an air outlet; the rotating shaft is penetrated through the middle part of the fermenter; a plurality of blades which are forwards slantwise are extended on the rotating shaft; the motor drives the rotating shaft to rotate so that the blades fixed on the rotating shaft drive organic materials to synchronously rotate along with the blades and push the organic materials forward from the front end to the back end; the air purifier is positioned at the upper part of the back end of the fermenter; and the two microwave electromagnetic heaters are respectively arranged at the two ends of the bottom of the outer wall of the fermenter. The stationary type organic fertilizer fermentation machine realizes the continuous fermentation of organic fertilizers, is high-efficiency and energy-saving, has strong practical applicability, strong adaptability and more complete functions and can be matched with the traditional bacterial agents. The stationary type organic fertilizer fermentation machine can adapt to multiple raw materials and the mixture of raw materials with different moisture contents as well as multiple climatic environments.

Manufacturing process and application method of ginseng bio-organic fertilizer

The invention provides a manufacturing process and an application method of a ginseng bio-organic fertilizer. By the manufacturing process and the application method, since ginsengs grow continuously in the same place for years, with the extension of the growing years, the problems of serious diseases, yield reduction and quality reduction of ginsengs are caused, the soil conditions deteriorate gradually and the fertility is reduced. The ginseng bio-organic fertilizer is prepared from the following raw materials in percentage by weight: 0.2-0.5% of a composite microbial agent, 0.2-1.0% of composite amino acid, 60.0-80.0% of organic material main ingredient and 10.0-30.0% of organic material auxiliary materials through composting together. The bio-organic fertilizer is spread on the surface of soil uniformly during soil preparation, the dosage is 2-10kg.m<-2>; through turning and rotary tillage, the fertilizer is mixed uniformly with 20cm deep bed soil, and the ginsengs are planted after seven days. By the manufacturing process and application, the problems of gradually deteriorating soil conditions and reducing fertility during the ginseng growing process are solved, the purpose of fertilizing soil, reducing diseases of ginsengs and improving yield and quality is achieved, and meanwhile, the soil ecological environment is protected.
