Embodiment 1

[0024] A method for biological treatment of slaughterhouse sludge and feces, the treatment method comprising the steps of:

[0025] In the first step, 30% of animal manure, 3% of soybean meal, 10% of bagasse, 3% of distiller's grains, 5% of wheat bran, 10% of corn straw and slaughterhouse sludge with a water content of 70% are used in proportion. The raw materials are mixed and stirred evenly, and the thickness of the mixture is 30 cm;

[0026] In the second step, the uniformly stirred mixture is heated to 30°C and kept at a constant temperature;

[0027] In the third step, the housefly ovum accounting for 10% of the weight in the mixture is evenly scattered on the surface of the mixture, and covered with an equal proportion mixture of bagasse, wheat bran and distiller's grains, and the thickness of the covering layer is 2 cm;

[0028] The fourth step is to wait for the housefly eggs to hatch and grow into adults, and collect the adults with a collector. It takes 7 days in to...

Embodiment 2

[0032] In the first step, 50% of animal manure, 2% of soybean meal, 5% of bagasse, 8% of distiller's grains, 5% of wheat bran, 8% of corn straw and slaughterhouse sludge with a water content of 50% are used in proportion. The raw materials are mixed and stirred evenly, and the thickness of the mixture is 25 cm;

[0033] In the second step, the uniformly stirred mixture is heated to 42°C and kept at a constant temperature;

[0034] The 3rd step, the housefly ovum that accounts for 8% by weight in the mixture is evenly scattered on the surface of the mixture, and is covered with an equal proportion mixture of bagasse, wheat bran and distiller's grains, and the thickness of the covering layer is 3 cm;

[0035] The fourth step is to wait for the housefly eggs to hatch and grow into adults, and collect the adults with a collector. It takes 5 days in total. During this period, the temperature is kept constant at 42°C and the humidity of the mixture is kept constant at 70%;

Abstract

The invention discloses a biologic treatment method and a production method of slaughter house sledge and feces. The theory that a great amount of organisms are consumed in the growth process of housefly larva is utilized, substances of grease, protein and the like in the sledge and feces can be effectively degraded, and the purpose of sledge harmlessness is finally achieved. According to the methods, the following raw materials in percentage by weight are mixed up: 30-50% of animal feces, 1-3% of bean pulp, 3-10% of bagasse, 3-8% of distiller grain, 3-5% of wheat bran, 5-10% of cornstalk, 3-10% of housefly egg and the balance of slaughter house sledge. The methods have the characteristics of safety and environment friendliness in a treatment process, high treatment efficiency, low energy consumption in the treatment process, and no waste gases, waste liquids and the like, various wastes can be treated at the same time in the treatment process, the various wastes can be finally converted into biologic organic fertilizers and biologic feed raw materials, industrialization and earning in sledge treatment are facilitated, the production cost of companies is lowered, and comprehensive popularization and wide application are facilitated.

Description

technical field [0001] The invention relates to a method for treating organic sludge, in particular to a biological treatment method for slaughterhouse sludge and feces. Background technique [0002] A large amount of biological feces will inevitably be produced in slaughterhouses, and because of the frequent need to flush pens and the inevitable generation of sewage containing biological blood, fat and other organic substances during the slaughtering process, resulting in When wastewater is treated, a large amount of excess sludge will be produced, and this kind of excess sludge has high protein content, is not easy to dehydrate, oily, sticky, difficult to treat, high in treatment cost, and unsatisfactory in effect, thus becoming a problem Important issues of slaughterhouse development and environmental protection. [0003] In order to overcome this problem, the main methods of sludge disposal in China include landfill, incineration and land use. Although the treatment of ...
