The invention discloses a water seepage and flood drainage system based on a sponge city. The water seepage and flood drainage system comprises an artificial wetland, wherein the artificial wetland is connected with a buffer tank by virtue of a second water pipe, and the buffer tank is connected with a river by virtue of a first water pipe; the artificial wetland is successively provided with a sterilizing layer, a first isolation layer, a water storage layer and a planting layer from bottom to top; soil is arranged in the planting layer, and emergent aquatic plants are planted on the planting layer; coarse sand is arranged in the water storage layer; a mud separation plate for blocking mud and sand is arranged in the first isolation layer, and the mud separation plate is wrapped with geotechnical cloth; and a plurality of volcanic rocks are arranged in the sterilizing layer. The water seepage and flood drainage system based on the sponge city solves the problem that the rainy and flood water is difficult to seep and accumulate for use; and meanwhile, the system can effectively alleviate the flood leak pressure of a river, can improve the convenience of the municipal water application and can realize a function of seeping, collecting, purifying, storing and utilizing the river water and rainy water.

The invention discloses a domestic shoe washer. Shoes are placed in a cage type rotary disc or on a shoe rack of a support type rotary disc for rotating and vertically-vibrating washing in an inner cylinder, and dirt on the shoe sole and shoe vamp is removed through constant rinsing and flushing and precipitated into a sand filtration cavity. The domestic shoe washer also has an ultrasonic cleaning function, a rotation dewatering function and a drying function. By arranging an ultraviolet germicidal lamp and ozone degerming equipment, bacteria in shoes can be effectively killed while shoes are cleaned. The domestic shoe washer is convenient to use and sanitary.

The invention discloses a method for treating scouring water of stock preparation by a straw pulp wet method. The method comprises the following steps: (1) an inclined wire is used for filtration, and filtered water enters a buffer pool; (2) chemical reaction is performed, wherein the water in the buffer pool is sent to a catchment reaction pool by a lift pump, and a flocculating agent is added to a transfer piping in front of the lift pump; and (3) waste water after reaction enters a flotation tank for air floating through the lift pump, a polyacrylamide solution is added to an outlet of thelift pump, and the water after air floating treatment is drained to a trench or is recycled for wet stock preparation. Compared with the medium wastewater treatment, the method has simple process andequipment, can become a treatment unit independent of medium wastewater, and can flexibly adapt to the fluctuation of yield in production, not only meet production requirement, but also achieve the aim of environmental protection, thereby reducing load of treating the medium wastewater, reducing the sediment content in stewed black liquor, and reducing interference to an alkali reclaim system. The method has the advantages of good effect of water treatment and lower operation cost, and the treatment cost of 1 ton of water is between 0.5 and 2.3 Yuan.

The invention discloses vegetable harvesting apparatus. The vegetable harvesting apparatus comprises operation tracks, a hanging beam and a harvesting device; each operation track comprises a mountingbase, a guide rail, a close mechanism and a cleaning mechanism, the lower part of the mounting base is embedded under the ground, the guide rail is laid on the mounting base, the close mechanism is used to close the guide rail, the cleaning mechanism is used for washing the guide rail by spraying water, the inner side of a close plate is provided with a support block, an end of the support blockis fixed with the inner side of the close plate, and the other end of the support block supports against the guide rail when the close plate is closed; the hanging beam is erected between the two operation tracks, supporting pieces are arranged below the hanging beam, and the lower ends of the supporting pieces are provided with track wheels; the harvesting device is suspended at the bottom of thehanging beam, and the harvesting device comprises left and right rollers, left and right blades, gas suction modules and shoveling modules; and the left and right rollers are parallel to each other and have a certain distance, an involving space is formed during rotating, the left and right blades cut vegetables in the involving space, the gas suction modules are used for adsorbing the cut vegetables on the surfaces, and the shoveling modules shovel the vegetables adsorbed on the surfaces of the rollers.

The invention discloses an oil-gas-water-sand four-phase separator, which comprises a tank body, a swirl tube is connected to the top of the front end of the tank body, a liquid inlet pipe is connected to the swirl tube, and the lower end of the swirl tube is connected to the inside of the tank body through a swirl down pipe. Connected; the top of the tank is also connected with a gas phase outlet; the tank is provided with a corrugated plate group connected to the inner wall of the tank, an oil weir plate, an oil chamber and a water chamber in sequence from front to back; the lower end of the oil chamber is connected with an oil discharge pipe, and the lower end of the water chamber A drain pipe is connected, and a baffle curved plate is connected to the front side of the tank body. The lower end port of the swirl down pipe faces the baffle curved plate, and an inclined downstream plate is arranged under the baffle curved plate, and both sides of the downstream plate are connected to the tank. On the side of the body; below the downstream plate, there is a sand storage tank connected to the bottom of the tank, and the lower end of the sand storage tank is provided with an opening and closing valve; the bottom of the tank is connected to a sediment cleaning machine that can automatically clean the sediment on the bottom of the tank components. The separator can not only realize the effective separation of oil, gas and water, but also realize on-line and off-line sand cleaning, and the cleaning is more thorough.

The rope-type integral transverse tension stacked beam ecological water intake gate and its operation method include a gate frame, a lock chamber, a gate storehouse, a power mechanism, and a track. The gate frame is formed of several layers of empty box gate stack beams; , respectively fixed on the top of the outer wall of the lock chamber and the door warehouse, and the two power mechanisms respectively drive the gate frame to slide along the track through the wire rope and the pulley block to change the lateral opening of the gate frame; the bottom empty box gate is equipped with a detachable The detachable rolling door box is located on the upstream side, and there is a rolling door leaf inside. A floating ball is connected to the top of the rolling door leaf. The change of the upstream water level drives the floating ball to make the rolling door leaf rise and fall to change the gate. The longitudinal opening of the frame. The invention uses flexible rope parts to ensure the normal opening and stable operation of the gate; adopts the form of an empty box gate, and is equipped with a purification device inside to ensure the water quality of the water discharged into the downstream.
