And blocked filter holes can be quickly disassembled and cleaned, so that continuous and efficient operation of the system is guaranteed.

This utility model relates to the field of wastewater treatment technology and discloses a wastewater treatment and recycling device. The device includes a base, a main body fixedly connected to the top of the base, a sewage inlet fixedly connected to the outer wall of the main body, a filter mechanism fixedly installed on the inner wall of the main body, a sand and gravel layer fixedly installed on the inner wall of the main body, and a neutralization and stirring mechanism fixedly installed at the bottom of the sand and gravel layer. To treat acidic and alkaline substances in wastewater, the device operates by starting a motor. The treated water permeates through a partition layer, flows through a mesh cylinder to the neutralization layer, and appropriate chemicals are added. The main shaft drives a stirring rod, causing a sliding column to rotate. The sliding column is lifted by a protruding inclined surface, stretching a telescopic rod and a spring. The sliding column slides along the low inclined surface, and the spring's rebound force pulls the stirring rod, causing the stirring rod to rotate and move up and down simultaneously, thus ensuring a more complete neutralization reaction of the treated water.

This utility model discloses a dust and hydrogen sulfide control system for coal mining face, including a dust removal module and a hydrogen sulfide monitoring module. The dust removal module includes a first chamber, a second chamber, and a third chamber. A filter screen is installed in the second chamber to filter particulate matter in the air. Aerosol components are installed in the first and third chambers to intercept and set off airborne dust. Air enters the hydrogen sulfide monitoring module, where an alkaline aerosol component generates alkaline aerosol to neutralize the hydrogen sulfide. This utility model achieves high-quality dust removal by sequentially performing aerosol, filtration, and aerosol processing on dust in the dust removal module. Simultaneously, the hydrogen sulfide monitoring module generates alkaline aerosol of corresponding concentration based on the hydrogen sulfide concentration in the air, ensuring sufficient neutralization of the hydrogen sulfide and effectively reducing dust and removing hydrogen sulfide from the coal mining face.
