A kind of water purification equipment with multi-layer purification space

Abstract

The invention relates to a water purification device with a multi-layer purification space, which comprises a purification device main body, the purification device main body comprises a lower sealing sleeve and an upper sealing sleeve which are fastened to each other, and the lower sealing sleeve comprises a bottom plate and an outer seal arranged on one side of the bottom plate A first annular filter cavity is enclosed between the outer sealing sleeve and the upper annular sealing plate, a second annular filtering cavity is enclosed between the upper annular sealing plate and the lower annular sealing plate, and the lower annular sealing plate is enclosed by the upper cover plate and the bottom plate. A third annular filter cavity is formed, and the precision filter assembly divides the third annular filter cavity into a precision filter cavity and a purification liquid cavity, and the equipment ensures that the sewage is purified in multiple layers in the equipment.

Description

technical field [0001] The invention relates to the field of sewage purification, in particular to water purification equipment with multi-layer purification spaces. Background technique [0002] Village and town sewage is mainly composed of domestic sewage and agricultural wastewater. The composition of domestic sewage is relatively fixed, mainly containing organic matter such as carbohydrates, proteins, amino acids, fats, etc., which is more suitable for the growth of bacteria and becomes a place for the survival and reproduction of bacteria and viruses; but domestic sewage generally does not contain toxicity, and has a certain fertilizer effect. to irrigate the fields. The composition of agricultural wastewater is diverse. Different seasons, different places, and villages and towns with different development goals require different treatment methods for the wastewater. The role of the sewage treatment station is to treat production and domestic sewage to meet the specifi...

AI Technical Summary

Problems solved by technology

Sewage treatment stations in industrially developed countries are already very common, but there are very few sewage treatment stations in villages and towns in my country. Traditional sewage treatment equipment is mainly of tubular or tank structure. Water purification materials are added to clean water pipes or purification tanks, and sewage After purifying the water quality materials, the impurities or pollutants in the sewage are intercepted, so as to achieve the purpose of purifying the water body. However, the problem with the traditional tubular or tank-type sewage treatment equipment is that the sewage purification area is limited, and the tubular or tank-type The purification area of ​​the structure is the cross-sectional area of ​​the tank body, the purification efficiency is very low, and the interior of the tubular or tank structure is mainly to install the purification water core, which needs to be replaced regularly, and the replacement cost is high
