Riverway sewage ecological treatment equipment

Abstract

The invention discloses riverway sewage ecological treatment equipment which structurally comprises a tank body, a sewage outlet and a water inlet pipe, the sewage outlet is formed in the lower portion of the left end of the front face of the tank body, and the water inlet pipe penetrates through the middle upper portion of the right side of the tank body. Because impurities stuck on the surface of a filter screen are easy to block sewage, and a push block of a cleaning device constantly moves back and forth to drive the filter screen to vibrate constantly, so falling of impurities by shakingforce is facilitated; impurities retained in the filter screen are removed through a scraper, the impurities retained outside the filter screen are reduced, the sewage is favorably accelerated to be filtered through the filter screen, the accumulation of a large amount of sewage is reduced, the backflow of the sewage is reduced, and the sewage treatment time and the sewage treatment speed are accelerated; because when impurities contained in the sewage pass through an opening, the impurities are easy to stay in the inner wall of the opening; and the impurities on the inner wall of the openingare removed by moving a blade back and forth through a push plate, the opening is kept smooth favorably, resistance of the impurities to the push plate is reduced, the moving speed of the push plate is increased, the vibration frequency of the filter screen is further increased, and falling of the impurities on the outer wall of the filter screen is accelerated.

Description

technical field [0001] The invention belongs to the field of sewage ecology, and more specifically relates to a kind of river sewage ecological treatment equipment. Background technique [0002] Discharge untreated industrial wastewater and domestic sewage directly into the river, causing the water quality of the river to gradually deteriorate and affect the normal survival of organisms. The sewage treatment and purification tank is used to purify the river sewage, and the river sewage is pumped out by the pump It is transported to the inside of the pool, and the impurities in the sewage are filtered through the filter and then discharged. In order to fully filter the impurities in the sewage, a multi-layer filter is installed inside the purification pool; in the prior art, the sewage treatment purification pool is used to treat river sewage At the same time, the impurities filtered by the filter screen remain on the surface of the filter screen, and the impurities retained ...

[0002] Discharge untreated industrial wastewater and domestic sewage directly into the river, causing the water quality of the river to gradually deteriorate and affect the normal survival of organisms. The sewage treatment and purification tank is used to purify the river sewage, and the river sewage is pumped out by the pump It is transported to the inside of the pool, and the impurities in the sewage are filtered through the filter and then discharged. In order to fully filter the impurities in the sewage, a multi-layer filter is installed inside the purification pool; in the prior art, the sewage treatment purification pool is used to treat river sewage At the same time, the impurities filtered by the filter screen remain on the surface of the filter screen, and the impurities retained on the surface of the filter screen are easy to block the sewage, causing the speed of sewage to be filtered through the filter screen to slow down, and the speed of drainage slows down. Accumulation, the filtered sewage flows back and mixes with the unfiltered sewage, increasing the time of sewage treatment
