According to the larvae, one of the invertebrates is one of the genus Insecta and the beetle, mainly distributed in the tropics and subtropics, but some species of habitat have expanded to temperate and even cold regions. At present, there are about 1,200 species of worms recognized worldwide, including small species of less than 20 mm and large varieties of body length of 180 mm or more. In the arthropods, the worm is one of the largest insects in the group. The mouthparts are chewable. The adult body is hard. It usually has four wings. The front wing is specialized into leathery or horny, called coleoptera. The hind wings are membranous and superimposed. Below the wing sheath; it belongs to a completely metamorphous insect. It must undergo four stages: egg, larva, pupa, and imago. The larva is the main feeding stage, and its food is mainly caused by corruption. Sexual organic foods, such as organic soils and even animal manure; its excrement is mainly granular, which is a good source of slow-acting fertility improver after drying, and can be used as a soil loosening agent to improve soil ventilation. Sex.

The recycling of industrial process waste is based on the technology of resource recycling and recycling, converting waste into useful substances, reducing the impact on the environment and ecology, achieving the purpose of natural resource conservation, and improving the efficiency of industrial operations. Among them, from the perspective of the diffusion and migration of pollutants, sludge is generally much more mobile than other solid wastes, so it is easier to form a wider range of environmental impacts.

Sludge is a solid sedimentation material produced by water and sewage treatment processes. The sludge source can be divided into sludge produced by Minsheng Sewage Treatment Plant and industrial output sludge. The total amount of sludge produced by the people is about 500,000 tons per year, and the proportion of organic matter is higher than that of industrial sludge. Industrial sludge produces about 2 million metric tons per year, of which organic sludge accounts for 35% and inorganic sludge accounts for 65%. If the sludge is discharged directly into the water body, it will cause various pollutants to enter the water system by means of transmission, diffusion and conversion, completely losing the environmental protection function of the sewage treatment facilities. At present, in the domestic sludge treatment method, although the sludge is subjected to treatment procedures such as digestion, conditioning, concentration, dehydration and drying, the subsequent treatment is mostly carried out by sanitary burial or incineration, resulting in shortened service life of the landfill and the incineration plant, and incineration. In organic sludge, the water content is higher than that of general urban waste. For every ton of dewatered sludge (water content 80~85%), about 40~100 liters of fuel is needed to support combustion, which is costly and consumes energy. At present, organic sludge directly used as a soil fertility improvement material is still prohibited by China's laws and regulations. Although it can be used for composting or other agricultural purposes through microbial treatment, heavy metals and other unknown organic substances are produced for industrial organic sludge produced by the photovoltaic industry. The doubts about the accumulation of composting products limit their use in agriculture.

In view of this, the inventor has been in the process of researching and improving the existing structures and defects by providing rich experience in design and development and actual production of the relevant industries for many years, and to provide a method for recycling organic sludge with a worm to achieve The purpose of better practical value.

The method for treating organic sludge by the worms of the invention is mainly based on industrial organic sludge as raw materials, and in composting production equipment with compost, baking powder, straw, sawdust, defoliation, nutritional additives, bacteria Mixing and blending, using the mixed breeding material to feed the larvae, and then feeding the worms, eating and digesting, and decomposing the sludge to produce the manure, which is dried and used as a good slow-acting fertility improvement and can improve soil ventilation. Sexual soil amendment; thereby, to achieve the purpose of using the worm as a bioreactor for the treatment of organic sludge, and to build a combined environmental pollutant treatment by breeding with the value of ecological recultivation Organic sludge treatment technology for resource, ecological conservation and ecological conservation concepts.
