Embodiment 1

[0028] Such as figure 1 As shown, in the pig house built on the high bed, every two pig houses share about 5 square meters of pig latrine 1 for pig excrement and pig urine. Leaky manure board 2, there is a rectangular movable manure collecting tank 3 under the manure dropping board, plant litter, such as wood chaff, is placed at the bottom of the manure collecting tank 3, and then probiotics are inserted, such as lactic acid bacteria, bacillus and other probiotics Community makes it become bacteria bed 4, and the thickness of bacteria bed is not more than 20cm, and initial stage is 18cm in the present embodiment, and it is controlled to be not more than 20cm in the process of treatment, then bedding one deck nylon gauze 5 (nylon gauze) on the bacteria bed surface The edge part of the tank is extended to the outside of the side plate of the rectangular tank to facilitate unloading. The nylon gauze ensures that pig urine can pass through, while the solid part of pig manure and b...

Embodiment 2

[0030] For pig farms in the cold northern regions, heat-preservation lamps can be installed in pig toilets, or heating wires can be sewed on nylon gauze to consume a certain amount of electricity to increase the temperature and ensure the normal growth temperature of black soldier flies and microorganisms (greater than 20 ℃), other operating procedures are the same as in Example 1.

Abstract

The invention discloses a method which is used for processing pig excrement with black soldier fly larvae and easy and convenient to conduct. Excrement and urine excreted by pigs leak from an excrement leaking plate of a pig toilet and fall into an excrement tank below, the solid pig excrement is eaten and digested by the black soldier fly larvae and then converted into insect protein, and the liquid pig urine leaks into a bacterium bed below a nylon gauze element and is digested and processed by beneficial microorganisms in the bacterium bed. After the black soldier fly larvae mature, the black soldier flies are caught by removing the nylon gauze element, a new nylon gauze element is installed, and new black soldier fly larvae are added for circulation processing. In this way, a large amount of pig excrement and pig urine produced dispersedly can be processed with low cost, without pollution and resourcefully, and a clean and safe pollutant processing scheme is provided for intensive breeding large and medium pig farms.

Description

Technical field: [0001] The invention belongs to the field of manure treatment, and in particular relates to a simple method for treating pig manure by using black soldier fly larvae. Background technique: [0002] The black soldier fly Hermetia illucens is an insect of the Diptera Soldier Fly family. Its English name is Black Soldier Fly, also known as the bright flat-horned soldier fly. The larvae are scavengers and eat a wide range of food. It is commonly found near pig pens and chicken houses in rural areas, and eats fresh pig manure and chicken manure. [0003] Black soldier flies are native to the tropical savannahs of South America, and then spread to North America. After World War II, with the extensive transportation and flow of personnel and materials, black soldier flies quickly spread to most areas in temperate, subtropical and tropical regions. There are specimen records or research documents in Hainan, Guangdong, Guangxi, Fujian, Hebei, Sichuan, Hong Kong, and...
