[0002] Sludge is generated during the operation and maintenance of urban facilities related to urban life and urban life activities. According to the source, it can be divided into sewage plant sludge, water supply plant sludge, drainage pipe sludge, dredging sludge and construction mud. The properties of sludge from different sources vary greatly, and the corresponding treatment and disposal technical requirements and resource utilization methods are also different.

[0003] According to Chinese patent publication number CN 217202473 U, an urban sludge earthworm ecological treatment reactor is disclosed, comprising a fixed bracket, one side of the fixed bracket is fixedly connected to a reaction box, one side of the reaction box is connected to a sludge pipe, the inner side of the reaction box is provided with an ecological treatment layer, the inner side of the reaction box is provided with a sand and gravel layer, and the inner side of the reaction box is provided with a filter filler layer; earthworms are placed inside the set ecological treatment layer, and a part of the added sludge can be digested and absorbed by the earthworms, and the other part is decomposed by microorganisms, so that the pollutant content in the sludge is significantly reduced, and the earthworm feces can be used as microbial food or high-efficiency agricultural fertilizer and soil conditioner, so that the cost of sludge treatment by this equipment is significantly reduced, which is beneficial for people to use. Moreover, during the treatment process, due to the high water content in the sludge, the sewage can be discharged after filtering through the sand and gravel layer, the filter filler layer and the quartz sand layer, which avoids pollution to the environment while reducing the difficulty of people's treatment.

[0004] However, the above device has the problem that after the earthworms are used to treat the sludge, the treated sludge and earthworms inside the reaction box need to open the upper protective cover to take out the treated fertilizer and earthworms, and the earthworms and fertilizer need to be separated later. Utility Model Content

[0005] The purpose of the utility model is to provide a reactor for ecological treatment of urban sewage sludge and earthworms, so as to solve the problems raised in the above-mentioned background technology.

When the fertilizer above the feeding frame is almost full, the baffle is inserted into the slot opened on the left side of the feeding frame. The sunlight shines on the fertilizer above the feeding frame. The earthworms inside the fertilizer drill under the fertilizer due to the high external temperature. The earthworms drill into the through hole opened above the feeding frame and slide into the collection frame below. Inside the dynamically connected collection box, the staff can also use a scraper to scrape the fertilizer above the feeding frame to allow sunlight to reach the inner fertilizer faster. When all the earthworms inside the fertilizer above the feeding frame have drilled into the collection box, take out the baffle and repeat the above process until all the fertilizer inside the reaction box has flowed out and the earthworms have drilled into the collection box. Then, grab the handle to take out the collection box inside the collection frame, pour the earthworms inside the collection box into the reaction box again, and let the earthworms continue to process the sludge, thereby achieving the effect of convenient collection of fertilizer and earthworms.
