Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of sewage treatment devices, and in particular to a high-turbidity sewage treatment device. Background Technology
[0002] High-turbidity wastewater needs to be treated by wastewater treatment devices, such as the utility model patent with application number 202120592699.0, entitled "MBR Treatment Device for High-Turbidity Wastewater Treatment". This patented device uses fiber membranes, inlet channels and treatment channels to allow water molecules to pass through the thousands of pores on the hollow fiber membranes after the wastewater passes through the membrane tubes. Activated sludge, bacteria and viruses are trapped on the outside. The aeration mechanism fills the outer surface of the MBR membrane tank with a large number of bubbles. Under the flushing of the bubbles, the bacteria and sludge trapped on the membrane surface are washed away, so that the wastewater can be recycled after treatment. However, after long-term use, this patented device is prone to clogging due to the accumulation of a large amount of sludge on the MBR device, causing the device to malfunction. Utility Model Content

[0010] Preferably, the side of the sewage chamber has an opening, and an air inlet pipe aligned with the ventilation chamber is fixedly connected to one outer wall of the chamber.

[0012] Compared with the prior art, the present invention provides a high-turbidity wastewater treatment device, which has the following beneficial effects:
[0013] Wastewater is fed into the discharge chamber through the inlet pipe via a movable block. High-turbidity wastewater is impacted by the separator, causing initial disintegration of clumps, which facilitates subsequent treatment. Motor 1 is activated, driving a lead screw to rotate in both directions. The lead screw moves a lifting plate up and down, which in turn moves a movable column up and down. The movable column then moves the movable block up and down, squeezing sludge and other solid materials downwards, causing them to accumulate at the bottom of the discharge chamber. The movable column then closes the separator, stopping wastewater injection while the movable block is squeezing the accumulated sludge, reducing the impact of wastewater sloshing on the sludge compression. The movable block then moves a pointed plate, which presses against the bottom of the discharge chamber. The lumpy and strip-shaped objects in the accumulated sludge are crushed, making the subsequent sludge discharge of the device smoother and preventing the device from being blocked by sludge. Motor 2 is started, which drives the rotating shaft to rotate, and the rotating shaft drives the spiral plate to rotate. The spiral plate discharges the sludge from the device through the sewage pipe. Aeration or other neutralizing gases are sent into the air inlet pipe and the air vent pipe. The gas enters the air vent chamber through the opening, which is beneficial for the disinfection and other treatment of sewage. The pump is started, and the pump draws the sewage into the reaction chamber. The water is discharged through the membrane bioreactor body. The electric moving column 2 of the lifting plate moves, and the moving column 2 causes the membrane bioreactor to shake continuously, which helps to keep the membrane bioreactor body from being blocked for a long time and improves the drainage and sewage discharge efficiency of the device.
