Description

Sulfur autotrophic continuous sand flowing filter

Technical Field

Background

With the development of science and technology and the improvement of water treatment requirements, a continuous sand filter is generated, and the continuous sand filter is a common water treatment device for removing suspended matters and fine particles in water. When filtering, the raw water is supplied by a high-level water tank, then enters from a bottom annular water distribution pipe of a sand flow filter, and is uniformly baffled by an internal conical water guide channel to enter into a filter bed, the water flows upwards and is fully and uniformly contacted with a filter material, suspended matters in the raw water are trapped on the filter bed, clear water overflows and is discharged by an effluent weir at the top, and quartz sand with trapped pollutants is lifted to a sand washing device (three-phase separator) at the top through a gas stripping device at the bottom for washing while filtering. The power for extracting sand is compressed air, and the pressure is 0.5-0.7 MPa. Due to the intense friction of water, sand and compressed air in the sand extraction pipe, the pollutant trapped by the sand is eluted. The cleaned sand returns to the filter bed from top to bottom in the sand washer due to gravity, and sand washing water is discharged through a separate pipeline, so that the whole continuous circulation sand washing and filtering process is completed.

Compared with the traditional fixed bed filter, the continuous flow sand extraction and washing mode is adopted, and the continuous operation can be realized without shutdown for backwashing. However, the following problems are common to continuous flow sand filters currently on the market: the equipment is high, usually above 6 m; contaminants with high density cannot be removed, are easy to accumulate at the bottom of the filter bed and need to be improved.
