Automatic earthworm biological-composting sludge disposal system and application method thereof

Abstract

The invention discloses an automatic earthworm biological-composting sludge disposal system and an application method thereof. The system comprises a biological lixiviation pre-treatment system, a static decomposing pre-treatment system, an automatic feeding system, a modular composting system and an automatic earthworm/cocoon screening and collecting system. The biological lixiviation pre-treatment system and the static decomposing pre-treatment system are used for pre-treatment of materials for culturing earthworm, and the treated materials are delivered in the automatic feeding system for automatic feeding to an earthworm box; after feeding to the earthworm box is finished, earthworm cocoons are fed in, and the modular composting system is used for culturing the earthworm cocoons; the raw materials and auxiliary material in the earthworm culture box are screened and collected as three types of products, namely, earthworms, earthworm cocoons and wormcast through the automatic earthworm/cocoon screening and collecting system. The system has the advantages that manual work and cost are both reduced while output is increased by application of a high-automatic production mode; earthworms, earthworm cocoons and wormcast are separated thoroughly at one step and pure wormcast with good effect is obtained; the difficulty in thorough separation between the parent and the filial generation of earthworms is overcome.

Description

technical field [0001] The invention relates to the technical field of earthworm biocomposting disposal, in particular to an automatic earthworm biocomposting sludge disposal system and an application method thereof. Background technique [0002] There are many disadvantages in earthworm biocomposting technology at present. The existing earthworm biocomposting technology basically has no pre-treatment technology or uses simple organic auxiliary materials as additives to adjust the sludge carbon-nitrogen ratio to make the sludge more suitable for earthworms to survive. However, this treatment is too extensive, prone to earthworm diseases and often leads to abnormal death of earthworms , is no longer suitable for large-scale production; at present, earthworm composting sites are mainly ground earthworm breeding beds in the open air or earthworm ground breeding beds or ponds in ordinary greenhouses, which are likely to cause secondary damage to soil and groundwater caused by th...

The existing earthworm biocomposting technology basically has no pre-treatment technology or uses simple organic auxiliary materials as additives to adjust the sludge carbon-nitrogen ratio to make the sludge more suitable for earthworms to survive. However, this treatment is too extensive, prone to earthworm diseases and often leads to abnormal death of earthworms , is no longer suitable for large-scale production; at present, earthworm composting sites are mainly ground earthworm breeding beds in the open air or earthworm ground breeding beds or ponds in ordinary greenhouses, which are likely to cause secondary damage to soil and groundwater caused by the leachate of sludge and other biological composting raw materials. Pollution, even if the ground culture bed has been treated with anti-seepage treatment, it is very difficult to control the leachate collection and bio-composting environment, and it is impossible to achieve centralized collection and unified harmless treatment; the existing open-air or ordinary greenhouse bio-composting can only Single-layer composting on the ground, the composting site utilization rate is low, and the land use area is too large, so that the living environment of earthworms in earthworm bio-composting cannot be effectively controlled, such as temperature, humidity, Ph value and pathogenic bacteria in the ground soil, causing earthworms to easily Causes seasonal large-scale death; and the utilization rate of composting sites is low. Excessive use of land is a great waste of land resources and greatly reduces production efficiency; traditional earthworm biocomposting relies on manual feeding, which is inefficient and unable to control the exact amount of feeding And the secondary treatment of raw materials, and the production environment is difficult to control, raw materials such as sludge are easily scattered in the site, resulting in dirty and smelly site; traditional earthworm biocomposting relies on open-air or vegetable greenhouse groun
