A kind of domestic water purification equipment and method suitable for decentralized rural household users

Abstract

The invention discloses a domestic water purifying apparatus suitable for distributed rural family users. The domestic water purifying apparatus comprises a water inlet region, a quartz sand filter region, a composite manganese sand filter region, an activated alumina adsorption region, a nano iron-aluminum hydroxide composite adsorption region, an activated carbon fiber adsorption region and a water storage region which are sequentially connected in series, wherein water flows into each region from the top and flows out from the bottom during normal water purification operation; a waterway connected between every two adjacent regions is provided with a check valve; the lower parts of the quartz sand filter region, composite manganese sand filter region, activated alumina adsorption region, nano iron-aluminum hydroxide composite adsorption region and activated carbon fiber adsorption region are respectively provided with an emptying valve, and the upper part is respectively provided with a backwashing valve and an inspection port; the lower part of the water storage region is provided with a water intake valve and a water drain valve; the water drain valve is connected with a backwashing pump; and the backwashing pump is respectively connected with each backwashing valve on the upper part of each region through a pipeline. The apparatus can effectively remove overproof iron, manganese, fluorine, arsenic, nitrates, organic matters and other substances in the ground water sources, and can sufficiently satisfy the water utilization demands for rural family users.

Description

technical field [0001] The invention belongs to the technical field of water purification, and in particular relates to a domestic water purification equipment and method suitable for distributed rural household users. Background technique [0002] Water is the source of life, and drinking water is the basic need for human survival and development. Safe and reliable rural drinking water is directly related to the physical and mental health and quality of life of rural residents, and is related to the realization of the goal of building a well-off society in an all-round way and a new socialist countryside. However, due to the aggravation of the pollution of rural water sources, the malignant tumors closely related to water pollution in the rural population of our country are on the rise. Most of the rural households are scattered and cannot use water purification plants to provide domestic water like urban users. With the improvement of rural living standards, many rural u...

Problems solved by technology

However, due to the pollution of various non-point sources and other factors in the vast rural areas, it is difficult for shallow groundwater to meet the requirements of the current "Drinking Water Hygienic Standards" (GB5749-2006), so there is an urgent need for a decentralized rural household user. Water purification equipment to meet the water needs of decentralized rural households

[0003] At present, water purifiers on the market are mainly developed for urban users, and are not suitable for rural households. At the same time, they are not adaptable to various water sources. Rural household users need a broad-spectrum water purification equipment, which is not suitable for underground water sources that exceed the standard. Iron, manganese, fluorine, arsenic, nitrate, organic matter and other substances can be effectively removed
