This utility model provides an automatic turning and turning device for sludge composting, relating to the field of sludge composting technology. It includes a turning and turning device frame, with a turning and turning guide frame welded to the top of the frame. The turning and turning guide frame has a hollow structure, with both its top and bottom being arc-shaped. Sludge is cut and folded by a high-speed moving baffle and enters the turning and turning guide frame, impacting and crushing the clumps in the sludge, improving the breaking effect on the compacted layer of the compost pile. This device is suitable for treating hard sludge compost and solves the problems of traditional sludge composting methods, which typically involve manual turning or using a bucket truck to shovel and scatter the sludge before turning. These methods fail to effectively stir or break up the compost pile during turning, making it difficult to break up the compacted layer, resulting in poor aeration. Furthermore, the thorough mixing of sludge with straw, sawdust, and other auxiliary materials requires multiple turnings, leading to low turning efficiency in sludge composting.

The application discloses a method for removing antibiotic resistance genes in straw sludge compost and application thereof, and belongs to the technical field of composting. In order to remove antibiotic resistance genes in municipal sludge, the application provides a method for removing antibiotic resistance genes in straw substrate sludge compost, specifically, antibiotic resistance genes are removed through combined action of strong oxidation and high temperature in aerobic composting. The method significantly reduces the abundance of antibiotic resistance genes in the compost sample on the basis of traditional aerobic composting technology, and reduces the potential risk of human health caused by recycling of the compost product in combination with an ozone oxidation technology and corn straw as a carbon source.

The utility model provides a kind of municipal sludge compost fermentation produced condensate waste liquid processing system, it is related to condensate waste liquid processing field, including mixed sedimentation tank, ozone reaction device, dilution tank, and mixed sedimentation tank is equipped with dosing opening, sewage inlet, condensate waste liquid enters into mixed sedimentation tank from sewage inlet, and reagent is added to mixed sedimentation tank by dosing opening, and the reagent is added is calcium hydroxide solution, and the sewage outlet of mixed sedimentation tank is connected by pipeline and the water inlet of ozone reaction device, and the water outlet of ozone reaction device is connected by pipeline and the water inlet of dilution tank;After reaction and deposition, sludge is entered into the feed end of sludge compost system by sludge outlet;Sewage and tail water addition ratio in dilution tank are 1:10+;Beneficial effect: the liquid after processing of the application is used as supplementary nitrogen fertilizer and garden greening water is mixed and irrigated, and the generated precipitate is used for compost fermentation to enhance sludge fertility, and the application achieves the purpose of source treatment and the treatment process is simple.

This utility model provides a sludge buffer silo with an impurity separation structure, relating to the field of sludge composting technology. It includes a silo and a filter; the silo has an inlet at the top and a outlet at the bottom; the filter is installed on the top of the silo, comprising an outer shell, a top cover, a filter cartridge, a motor, a rotating frame, a movable sleeve, and a spring; the bottom of the outer shell is connected to the top of the silo, and the top of the outer shell is connected to the top cover, with the filter cartridge located inside the outer shell; the motor is fixedly installed on the top cover, and its drive shaft is connected to the rotating frame, which is located inside the outer shell and surrounds the filter cartridge; the movable sleeve is slidably connected to the outside of the outer shell and is connected to the top cover. When sludge enters the filter, large particles of impurities are intercepted by the filter screen, preventing them from entering the silo. The filtered sludge is then discharged into the silo, effectively ensuring the quality of the sludge inside the silo.
