Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a biochemical wastewater treatment device. Background Technology

[0002] With the development of science and technology industries, serious environmental pollution has been caused. Among them, the direct discharge of biological and chemical wastewater seriously affects people's health. Therefore, in order to make wastewater meet the water quality requirements for discharge into a water body or for reuse, it should be purified and treated.

[0003] The patent publication number "CN212864396U" describes a "biological and chemical wastewater treatment device" that connects the inlet pipe and the outlet pipe at different heights on both sides of the settling tank. This allows wastewater to permeate to the top, causing large particles of impurities to settle inside the settling tank. This prevents impurities from accumulating on the first filter screen, thus eliminating the need for frequent cleaning of the first filter screen, saving filtration time, and improving work efficiency.

[0004] Although the device uses the water flow in the outlet pipe to drive the impeller to rotate, thereby enabling the movement of the screw conveyor shaft to automatically dispense reagents, in actual operation, the impeller rotation causes the screw conveyor shaft to move for reagent dispensing. The screw conveyor shaft has a certain travel distance, so the water that initially enters the outer shell lacks contact with the reagents, resulting in omissions in water treatment. Furthermore, after the water enters the outer shell and comes into contact with the reagents, it flows directly from the guide plate to the second screen for filtration and discharge, making it difficult for the reagents to have sufficient contact with the water, resulting in a low water treatment pass rate.
