Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a device for intercepting and separating suspended matter in wastewater. Background Art

[0002] Suspended matter refers to solid matter suspended in water, including inorganic and organic matter insoluble in water, mud, clay, microorganisms, etc. The content of suspended matter in water is one of the indicators to measure the degree of water pollution. Suspended matter is the main cause of water turbidity. Organic suspended matter in water bodies is prone to anaerobically fermentation after precipitation, causing the water quality to deteriorate.

[0003] Suspended solids separation is a necessary step before sewage treatment. Most of the existing methods of separating suspended solids from sewage still use simple devices such as filters to intercept them. This removal method is inefficient, and the filter will become clogged after intercepting too much suspended solids. In the later stage, it is necessary to manually replace or clear the filter regularly. Summary of the invention

[0016] 1. The wastewater suspended matter interception and separation device, wastewater enters the storage box through the water inlet nozzle, and the flocculant is put into the storage box through the dosing nozzle.

Conversely, by loosening the locking bolts, the combination plate and the locking rod are no longer locked. By pushing the combination plate to slide on the sliding rod, the gap between the combination plate in the filtration area can be adjusted, thereby realizing the squeezing and discharge control of water in the suspended matter.
