Description

Technical Field

[0001] The present invention relates to the technical field related to wetland sewage treatment and processing, and specifically provides a coastal wetland treatment device and a treatment method for chemical sewage. Background Art

[0002] Tidal and terrestrial basin wetlands are the ecological transition zone between the ocean and the land. Coastal wetlands are connected to the ocean and are the fusion of the ocean, rivers and land. Coastal wetlands have unique hydrological landforms, special environmental conditions, and obvious ecosystem functions. Coastal wetlands are an important component of maintaining the marine ecosystem and the survival of human society.

[0003] High-salt wastewater will cause salinization of the land during the discharge process, resulting in a decrease in soil fertility and affecting the ecological balance. High-salt wastewater refers to wastewater with a total salt content of at least 1%, which mainly comes from chemical plants and the collection and processing of oil and natural gas. This wastewater contains a variety of substances (including salt, oil, organic heavy metals and radioactive substances). The production of saline wastewater is extensive and the amount of water is increasing year by year. It is crucial to remove the impact of organic pollutants in saline wastewater on the environment. However, some fine sand and impurities will be mixed in the discharge process of chemical plants. When treating the salt wastewater, it will adhere to the main components of the equipment due to temperature reasons, and it will also cause crystal adhesion during the evaporation process, which greatly reduces work efficiency, increases the operating pressure of staff, and causes many inconveniences to staff.

[0014] A method for treating chemical wastewater in coastal wetlands, using any one of the above-mentioned chemical wastewater coastal wetland treatment devices, includes the following treatment methods: S1: With the assistance of workers or conveying equipment, high-salt chemical wastewater is put into the inside of the recycling box. Two sets of filters inside the recycling box can separate the mixed fine sand. The high-salt chemical wastewater flows into the lower part of the inside of the recycling box. Under the connection of the inclined filter, the fine sand can flow into the inside of the arc pipe under the scouring flow; S2: Then the second motor is connected to the power supply and started. Under the connection of the pulley group on the outer side of the output shaft, the first rotating shaft and the rotating drum rotate synchronously, and the first rotating shaft drives the multiple sets of blades on the outer side to stir in the box. At this time, a reagent for neutralizing the salt concentration can be added to reduce the salt content in the sewage, and the salt can be quickly dissolved under the heating of the heater. The rotation of the first rotating shaft can drive the second gear on the outer side of one end to rotate, and the first gear meshing with the second gear will drive the second rotating shaft to rotate, and then the multiple mounting rods and balls on the outer side of the second rotating shaft will rotate. The rotating balls will come into active contact with the lower surface of the filter, and then touch the fine sand that may be retained, so that the fine sand can fall into the inside of the arc tube and be collected, while also ensuring the sand filtering effect on the surface of the filter; S3: During the above treatment process, the salty sewage flows to the inside of the corresponding connecting box through the flow holes opened on the inside of the drum, and the drum rotates and fits with the rotating groove of the support seat, so that no substances adhere to the surface of the drum, and the outer sides of the two ends of the recovery box are driven by the hydraulic cylinder, and the first swing rod and the two second swing rods will cause the lower cross rod and the movable rod to move, so that the connecting rod at one end of the movable rod and the fixed plate can be horizontally extended and retracted below the inner side of the bottom box; S4: Then, when the first motor on the inner side of the fixed plate slowly approaches the rotating drum, the first motor can drive the connecting shaft corresponding to the output shaft to rotate, and the outer sides of the two connecting shafts corresponding to the outer sides of the fixed plate are equipped with chain groups, and the chain groups further drive the multiple elastic rods on the outer side to rotate and contact the outer surface of the rotating drum, so as to clean the outer surface of the rotating drum and the flow holes on the inner side, and touch and clean the adhered crystals.

[0015] S5: Finally, the worker sets up the slide bar outside the recycling box, and then pushes the slide bar from one end to move it to the sealing cover. The sealing cover opens, and the lower end of the slide bar can discharge the separated fine sand to the outside of the arc tube and discharge the fine sand through the guide table.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The sand filter recovery component can be used to process the highly salted fine sand and impurities that are input. The highly salted sewage can be finely filtered during the treatment process, and the impurities and fine sand can be recovered and discharged.

[0017] The first swing arm and the second swing arm can be driven by the hydraulic cylinder to push the connecting rod and the fixed plate toward the inside of the bottom box, so that the chain inside the fixed plate can rotate. At the same time, the elastic rod on the outer wall of one side of the chain can contact the rotating drum, thereby touching the outer wall of the rotating drum and the flow holes on the inside, reducing the probability of clogging crystal adhesion.

[0018] By setting up the first rotating shaft and the second rotating shaft, the second motor can drive the corresponding first rotating shaft to rotate. Under the connection of the first gear and the second gear, the fan blades and the balls can stir and knock the filter screen inside the recovery box respectively, thereby achieving the purpose of using chemicals to dissolve the highly salted sewage inside the recovery box and ensuring that the filter screen can continue to perform efficient filtration.

10. A method for treating chemical wastewater in a coastal wetland, using any one of the chemical wastewater coastal wetland treatment devices in claims 1 to 9, comprising the following treatment methods: S1: With the assistance of workers or conveying equipment, the chemical wastewater containing high salt is put into the inner side of the recovery box (2). The two sets of filter screens (4) inside the recovery box (2) can separate the mixed fine sand. The chemical wastewater containing high salt flows into the lower part of the inner side of the recovery box (2). Under the connection of the inclined filter screen (4), the fine sand can flow into the inner side of the arc tube (28) under the scouring flow; S2: The second motor (15) is then connected to a power source and started. When connected to the pulley group (12) on the outer side of the output shaft, the first rotating shaft (23) and the rotating drum (31) rotate synchronously. The first rotating shaft (23) drives the plurality of blades (27) on the outer side to stir the inside of the box.
