Water purification equipment with multi-layer purification space

Abstract

The invention relates to water purification equipment with multiple layers of purification spaces. PURIFICATION DEVICE COMPRISING A PURIFICATION DEVICE BODY, wherein the purification equipment main body comprises a lower sealing sleeve and an upper sealing sleeve which are buckled with each other; the lower sealing sleeve comprises a bottom plate and an outer side sealing sleeve arranged on one side of the bottom plate; a first annular filtering cavity is defined between the outer side sealing sleeve and the upper annular sealing plate; a second annular filtering cavity is defined between theupper annular sealing plate and the lower annular sealing plate, a third annular filtering cavity is defined by the lower annular sealing plate, the upper cover plate and the bottom plate, the third annular filtering cavity is divided into a precise filtering cavity and a purified liquid outlet cavity through the precise filtering assembly, and it is guaranteed that sewage is subjected to multi-layer purification 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
