The utility model relates to a submarine pipeline detection type underwater robot. It is used for accurate detection of underwater oil pipelines. The underwater robot (ROV) includes an ROV body, a fixed pipeline clamp device and a chain-type pipeline horizontal detection device; the ROV body serves as a carrier to provide power for the clamp device and the detection device; the clamp device passes through a linear guide rail slider mechanism The rotation of the left bracket and the right bracket is converted, thereby driving the rotation of the claws on the bracket, and finally the clamp device is converted into a clamping force on the pipeline, preventing the shaking and swing of the ROV body, and ensuring the reliability of the clamp work. It also ensures that the chain-type pipeline can provide a stable detection environment for the horizontal detection device. In the detection device, the flexible manipulator is equipped with detection equipment to detect the pipeline, and the horizontal rotation detection can be carried out on the basis of detection along the axial direction of the pipeline. At the same time, this kind of underwater robot adopts a flexible manipulator structure that can automatically attach to the pipe wall, and is suitable for most diameter pipes.

The invention discloses a concentrated sludge hydrothermal treatment method and system, and relates to the technical field of environmental protection. The hydrothermal treatment method of concentrated sludge of the present invention comprises: collecting concentrated sludge, filtering after first-stage pre-heating by venting steam, and then performing hydrothermal reaction after secondary pre-heating as a cold source medium through heat exchange by a heat exchanger; After the hydrothermal treatment, the released hydrothermal steam is recovered as the first-level pre-heating heat source, and the recovered liquid material is used as the heat source medium after being cooled by the heat exchanger and then collected and processed. This system is used in conjunction with the method described above. The present invention carries out hydrothermal reaction after filtering concentrated sludge and secondary pre-heating, avoids pre-dehydration, and saves treatment procedures; fully utilizes the waste heat of high-temperature materials after hydrothermal reaction, saves energy, and improves hydrothermal reaction efficiency; especially applicable It is suitable for small-scale and concentrated sludge treatment; its system structure is simple, it occupies a small area, saves equipment and operating costs, and is especially suitable for small-scale sewage treatment enterprises with limited land use.

The invention relates to a system for decentralized sewage and sludge biochemical treatment, which comprises a biochemical filtering bed for biochemical treatment for sewage and a sedimentation regulating tank connected with a sewage source, water distribution tubes are arranged on the surface of the biochemical filtering bed and connected with a water pump in the sedimentation regulating tank via a main water distribution tube, a sludge filtering bed is arranged near the sedimentation regulating tank which is provided with a sludge pump, the sludge pump is connected with the sludge bed via tubes, wherein grading of filler in the basement of biochemical filtering bed is reasonable, the filtering bed is fine in water permeability and microbiological survival environment, high in efficiency of sewage processing, and can avoid blocking and crusting, thereby the filtering bed is beneficial to long-term usage, as the drying stabilizing treatment on the sludge in the sedimentation regulating tank is achieved by the sludge filtering bed, pollution to others water source can be avoided, further as the sludge accumulating to a certain amount in the sludge filtering bed, one-time cleaning can be achieved and resourced utilization can be realized, thereby reducing the processing cost.

Disclosed are curing agent for solidification / stabilization of dewatered sludge of a sewage plant and application of the curing agent. Chemical components of the curing agent includes, by mass, from 3 to 8 parts of SiO2, from 25 to 35 parts of Al2O3, from 32 to 43 parts of CaO, from 15 to 23 parts of SO3, from 1 to 3 parts of Fe2O3 and from 0.1 to 0.3 part of Li2O. After the curing agent is added into the dewatered sludge, solidification materials quickly react with moisture in the dewatered sludge to form a needle-shaped framework, and accordingly the strength of solidified sludge is improved. Besides, the yield of products is increased along with reaction, the specific surface area of the products is large, the products have a high adsorption effect, and effects of stabilization and pollutant sealing are achieved along with increase of compactness of solidified bodies.
