The utility model discloses a treatment system for high-concentration desizing, slashing and dyeing wastewater, which is characterized in that sewage is subjected to quality-based and split-flow treatment according to different properties, desizing and slashing high-concentration sewage is independently collected and then is lifted to a homogeneous hydrolysis acidification pool and a high-efficiency anaerobic reactor for treatment through a pump, and then effluent is connected to a comprehensive sewage adjusting pool through a sedimentation pool; dyeing wastewater and ground flushing and domestic sewage are discharged to a grid well, a microfiltration grid and a comprehensive sewage adjusting tank; after being treated by different pretreatment processes, the wastewater respectively enters a comprehensive wastewater adjusting tank, and then is subjected to advanced treatment by a high multiplication biological treatment tank, a sedimentation tank, an intermediate water tank, a gas-liquid jet flow biological aeration filter tank, a high density clarification tank and a double-membrane method advanced treatment facility, so that pollutants are comprehensively reduced, and the quality of the effluent meets the production reuse water quality standard; and cyclic utilization can be realized. The system has the advantages of simple treatment flow, small occupied area, low construction cost, low operation cost, high automation degree, convenience in operation and management and the like.

This utility model relates to the field of stratified sampling in hydrogeological exploration, and discloses a stratified water-stopping device for geological exploration, including a pipe body, a partition, a shallow water layer suction pipe, a first filter head, a confined water layer suction pipe, a second filter head, a first drain pipe, a second drain pipe, a limiting mechanism, and a water inlet mechanism. The partition is fixed inside the pipe body, and two partitions are provided. The shallow water layer suction pipe, the confined water layer suction pipe, and the first drain pipe all seal through the pipe body. This stratified water-stopping device for geological exploration effectively prevents water from entering the pipe body during descent using an arc-shaped plate, ensuring that water from different layers does not mix. In addition, an electric cylinder is used to fix the pipe body in exploration wells with different inner diameters, which is highly applicable and facilitates the storage of pulleys, making the descent of the pipe body smoother.

The utility model discloses an urban landscaping vertical planting device which comprises a supporting frame, lifting mechanisms are arranged on the edges of the two ends of the upper end face of the supporting frame, and moving mechanisms which are controlled by the lifting mechanisms to move up and down are arranged on the edges of the two sides of the upper portion of the front face of the supporting frame. The moving mechanism comprises a sliding frame perpendicular to the supporting frame, a sliding groove is formed in the sliding frame, a lead screw is rotationally connected into the sliding groove, one end of the lead screw is fixedly connected with a driven bevel gear, and a second motor is fixedly installed at the bottom end of the sliding frame. On one hand, through the lifting mechanisms on the edges of the two ends of the upper end face of the supporting frame, the high planting unit can be lowered to the position convenient to operate, climbing operation and potential safety hazards are avoided, and maintenance difficulty and risks are reduced; on the other hand, the lifting mechanism and the moving mechanism work cooperatively, when the planting units are blocked during descending, the moving mechanism can drive the planting units to horizontally move and avoid, smooth descending is ensured, and the maintenance efficiency is improved.

This invention relates to a test tube capping device, mainly comprising an upper cover tray, a test tube tray, and a lifting platform. When the lifting platform rises, it lifts the test tube tray and the test tubes on it, causing the test tubes to engage with the upper cover mounted on the upper cover tray. After engagement, the lifting platform lowers the test tube tray and the test tubes, and the upper cover, already pressed against the test tubes, detaches from the upper cover tray and descends with the test tubes. Therefore, this invention can cap only the test tubes already mounted on the test tube tray, allowing for capping of a specific number of test tubes at specific locations without requiring capping the entire tray. Furthermore, the overall configuration of the device is more compact, the mechanism and operation are quite simple, stable and reliable, and cost-effective.
