Abstract

The invention discloses a pressure filter. The pressure filter comprises a closed filtering tank body, the interior of the filtering tank body is divided into a left chamber and a right chamber through a baffle, the right chamber is respectively provided with a sand layer and a coal layer, the sand layer is positioned at the bottom of the right chamber, the coal layer is positioned at the upper part of the sand layer, the left chamber is provided with a pressurizing device, the top of the filtering tank body is provided with an exhaust valve, the top of the filtering tank body is also providedwith a wastewater inlet, and the bottom of the filtering tank body is provided with a purified water outlet. The pressure filter is simple in structure, is similar to a common filter tank in the internal structure, and is mainly characterized in that pressure can be borne, and filtered residual pressure can be used for conveying effluent to a water utilization place. The pressure filter has the advantages of strong filtering capacity, small size and large equipment shaping and using maneuverability, and can be suitable for local treatment of some sewage.

Description

technical field [0001] The invention relates to the field of sewage treatment equipment, in particular to a pressure filter. Background technique [0002] Filtration is a technology that uses filter materials to separate impurities in sewage. Sometimes it is used for pretreatment of sewage, and sometimes it is used as final treatment, and the effluent is recycled or reused. In advanced sewage treatment technology, filtration technology is widely used. At present, the filtration appears in front of people with large-scale filtration systems, but for workshops or enterprises with a small amount of sewage, it is a waste of resources to filter, so it is very important to study a small pressure filter that can partially treat some sewage. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned technical problems, the present invention provides a pressure filter with small volume and strong filtering capacity. [0004] The technical sche...
