Description

Novel carousel filtering pond of integration self-cleaning

Technical Field

The utility model relates to a sewage purification technical field especially relates to a novel carousel filtering pond of integration self-cleaning.

Background

However, nowadays, the ecological environment is seriously damaged, the water pollution is serious, the protection of water resources and the treatment of water pollution become the most concerned problems of the modern society, along with the development of economy in China, the water demand of cities is continuously increased, so that the contradiction between supply and demand of water resources is increasingly acute, and the recycling of sewage after advanced treatment becomes an important link of water environmental protection engineering.

At present, rotary disc filters are more adopted in filter tanks for treating sewage and wastewater, particularly, fiber rotary disc filters are used more frequently, a central device for filtering by the fiber rotary discs is a middle filtering rotary disc, fiber wool filter cloth is arranged on the filtering rotary discs, and when sewage passes through the filter cloth, large-particle particles are adsorbed on fiber wool of the filter cloth, so that solid-liquid separation can be realized, and the effect of purifying water quality is achieved.

During the filtration of the original fiber rotary disc, partial sludge is adsorbed in the fiber wool filter cloth to gradually form a sludge layer, the filtration resistance of the filter cloth is increased along with the accumulation of the sludge on the filter cloth, and the water level of the filter tank is gradually increased. The liquid level change in the pressure sensor monitoring pond in the filter pond, when liquid level reachd the washing setting value (high water level) in this pond, can start the backwash pump, begin the cleaning process. The backwash time and period can be adjusted. Sludge on the filter cloth is sucked by the reverse suction device (a reverse suction sucker and a reverse suction pump) through the reverse suction pump to form a relatively closed negative pressure environment and is discharged out of a factory drainage system. During cleaning, the filter chamber can continuously filter, the friction between the original fiber wool filter cloth and the reverse suction sucker is considered, and the friction is acted by suction force, so that the depilation condition is easy to occur, the service life of the fiber wool filter cloth is shortened, and the problem is improved.
