Problems solved by technology

[0005] The current status of sewage treatment is high energy consumption and low efficiency. At present, urban domestic sewage treatment is the top priority of current and future urban water conservation and urban water environment protection. This requires us to continuously improve domestic sewage treatment facilities and equipment, and it's a matter of urgency

Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing:

[0024] A new type of quartz sand filter, which is composed of a device body 2, a filter material layer, a feed port, and an exhaust hole; the device body 2 and the upper and lower ends are provided with dome-shaped porous plates 15, and the outer sides of the dome-shaped porous plates 15 are respectively arranged There are two upper and lower heads 1 to assemble the equipment body 2 together, and a filter material layer is filled in the middle of the dome-shaped porous plate 15. The dome-shaped porous plate 15 is made of a 10mm thick steel plate, and the surface has multiple There are four holes, which can facilitate the inflow of water while blocking the pebbles. The filter material in the filter layer is composed of pebble layer and quartz sand layer. According to the fine process of sewage treatment, the appropriate quartz sand particle size can be selected.

Abstract

The invention provides a novel quartz sand filter, which belongs to the technical field of the papermaking industry. A filter layer of the quartz sand filter employs a quartz sand and pebble layer, the quartz sand filter is integrally pressure type filtering purifying equipment, the filter can remove suspended solids in water, silt is intercepted by a sand filter blanket, and thus, raw water is purified. The quartz sand filter is composed of a filter body (2), filter material layers, a feed inlet and an air vent. The upper and lower ends of the filter body (2) are provided with arched perforated plates (15), the outer sides of the arched perforated plates (15) are respectively provided with sealing heads (1) for assembling the filter body (2) and the arched perforated plates together, and the middle parts of the arched perforated plates (15) are filled with the filter material layers; the filter material layer is composed of a pebble layer and a quartz sand layer. The quartz sand filter provided by the invention can effectively remove suspended solids in water and has small filtration resistance, strong acid and alkali resistance and resistance to oxidation, which is beneficial for ensuring the quality of effluent under a variety of operation conditions; a filter material fully disperses during backwashing, and a good cleaning effect is obtained; and the quartz sand filter has the advantages of a wide application scope and a simple structure.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a novel quartz sand filter. Background technique [0002] In order to make the sewage meet the water quality requirements for drainage of a certain water body or reuse, and purify it. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. At present, urban domestic sewage discharge is the main source of water pollution. According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage, etc., while domestic sewage is sewage produced in daily life, which refers to a complex m...
