Description

Technical Field

[0001] This utility model relates to the field of plant purification technology for rural livestock wastewater under the ecological civilization city framework, specifically a plant purification device for rural livestock wastewater. Background Technology

[0002] Within the framework of ecological civilization city construction, rural aquaculture wastewater purification by plants refers to a low-cost, low-energy ecological governance technology that utilizes artificially constructed wetland ecosystems to convert organic matter and nitrogen and phosphorus pollutants in aquaculture wastewater into plant biomass through the triple action of root adsorption, microbial degradation, and physical filtration of aquatic plants, thereby realizing the resource utilization of pollution.

[0003] However, existing plant-based wastewater purification devices for rural livestock farming have the following drawbacks:

[0004] (1) Existing rural aquaculture wastewater plant purification devices have weak aeration and filtration functions. Existing plant purification devices rely solely on aquatic plants for purification, which is inefficient and cannot effectively filter impurities and particles, thus affecting the purification effect of aquatic plants.

[0005] (2) Existing rural aquaculture wastewater plant purification devices have weak secondary filtration function. Existing plant purification devices cannot filter large impurities and pollutants in wastewater. Contact with aquatic plants will cause the aquatic plants to die quickly. Utility Model Content

The filter screen 203 can perform secondary filtration on the sewage, so that impurities are retained in the filter screen 203. The connecting pipe 202 fixed to the fixed plate 201 is used to receive the sewage filtered by the filter screen 203. The connecting pipe 202 transmits the sewage to the aquatic plant planting board 204. Multiple aquatic plants are cultivated on the surface of the aquatic plant planting board 204 to adsorb harmful substances in the sewage and ensure the cleanliness of the purified water.

The exhaust valve 4 can release the pressure inside the sedimentation tank 102 when the pressure is too high due to the fermentation of sewage and impurities. It can be released periodically and does not need to be used frequently.

[0027] The filter frame 101 has an installation groove on one side, and an observation window 5 is installed on the inner wall of the installation groove. The filter frame 101 is placed in the aquaculture pond, and the position of the observation window 5 protrudes above the water surface, so that the staff can see the internal sedimentation through the observation window 5.

This ensures that large impurities or particles are initially filtered, ensuring the cleanliness of subsequent filtration and reducing the workload of staff.

[0032] The second step: After the filter screen 203 is connected to the transmission pipe 104, the pre-filtered wastewater enters the filter screen 203, where it performs secondary filtration, trapping impurities. The connecting pipe 202, fixed to the fixing plate 201, receives the filtered wastewater and transmits it to the aquatic plant planting board 204. This board is made of HDPE injection molding, with planting holes distributed in a matrix of 25 holes / m² on its surface.
