This utility model provides a high-efficiency and energy-saving integrated tank-pump pressure-stabilizing water tank, relating to the field of water supply equipment processing technology. It includes an integrated tank-pump pressure-stabilizing water tank assembly, with a filter component on its side, and reinforcing and buffer components on its top. The assembly comprises a water tank and an energy-saving pressure-stabilizing pump. In this utility model, multiple filter elements are installed inside the filter box, which effectively filters the water source, removing impurities and particulate matter to prevent them from accumulating inside the tank. The activated carbon box further adsorbs microorganisms in the water source, further purifying the water quality, reducing corrosion and wear of the tank, extending the service life of the integrated tank-pump pressure-stabilizing water tank assembly, and maintaining the cleanliness of the water inside the tank, preventing water quality deterioration due to bacterial growth caused by impurities.

The invention discloses a natural landscape revetment and a construction method thereof, and belongs to the technical field of landscape engineering, and the main body structure of the revetment sequentially comprises a rammed earth layer, a soil layer layered rolling layer and a sandy soil layer from bottom to top; 3-5 pieces of decoration scene stone are arranged in an upstream proper area every 12-15 m; a 2.5-3.5 m aquatic plant planting area is arranged in the midstream; the method comprises the following steps: arranging a wood pile at the downstream, arranging sandy soil, a wood bundle and the wood pile at the upstream area of the wood pile, adopting wickers of 1-5cm and 40-50cm in length as the wood bundle, nailing the wood pile into the soil by 1.5 m according to the distance of 1m, scion, and binding the wood bundle and the wood pile. According to the revetment, natural elements and ecological functions are combined, the construction method is simple and feasible, the stability of the revetment can be effectively enhanced, meanwhile, the attractive and natural landscape effect is created, and good ecological benefits and landscape value are achieved.

This application relates to a river ecosystem management device, belonging to the technical field of river ecological restoration and environmental protection. It includes a float, with a deployment mechanism on the outside of the float, a moving mechanism on the top of the float, and a catching mechanism on the bottom outer side of the float. The deployment mechanism includes a storage tank, the outside of which is opened inside the float. An extraction tube is fixedly connected to the top inner side of the float, and a retrieval tube is slidably connected inside the extraction tube. A docking assembly is fixedly connected to the top outer side of the extraction tube, and a metering tube is fixedly connected to the top of the retrieval tube. This application features a vertically movable retrieval tube that, when sliding within the extraction tube, utilizes the principle of pressure difference to extract the treatment material from the storage tank. The material is extracted to the metering tube for volume control, thereby achieving the effect of stably spraying the treatment material into the river after quantitative control.

This invention discloses a pretreatment process for dry gas from ethylbenzene production. The steps are as follows: the dry gas from ethylbenzene production sequentially enters a dry gas separator and coalescer, a dry gas water washing tower, a water-washed dry gas cooler, and a water-washed dry gas separator to remove organic amines and / or ammonia carried in the dry gas. The dry gas water washing tower is arranged from bottom to top as a first water washing section, a second water washing section, a third water washing section, ..., N water washing sections, where N≥2. A collection tank is set between two adjacent water washing sections. The bottom plate of the collection tank is equipped with a riser hole and a riser pipe to connect the two adjacent water washing sections. Each water washing section is arranged from bottom to top as a structured packing section and a water washing water distributor. The dry gas water washing adopts a multi-stage water washing process. Each stage of water washing uses a water washing circulation pump to circulate the water washing water. A water washing water filter is installed on the water washing water circulation pipeline of each stage. The water washing water adopts a method of partial circulation, continuous discharge, and continuous water replenishment. Using this invention, the amount of alkaline substances carried in the dry gas of ethylbenzene production feedstock can be effectively removed.
