Abstract
The present invention provides a kind of oxidation-absorbing synergic purifier, including self-priming dissolved oxygen acquisition equipment, rough filtering device and device for deep cleaning, the self-priming dissolved oxygen acquisition equipment includes the self priming pump being sequentially communicated, suction type air inhalator and gas-water separation valve, the gas-water separation valve, rough filtering device and device for deep cleaning are sequentially communicated, underground water to be processed is pumped into suction type air inhalator by the self priming pump, the suction type air inhalator is used to increase the dissolved oxygen content in underground water, the rough filtering device is used to remove the ferrous ion and manganese ion in underground water, the device for deep cleaning is for remaining iron in attached ground water, pollution by manganese object.Equipment provided by the invention can be used in the primary underground water inferior of high arsenic, high-speed rail, high manganese of purified treatment strong reducing property, ensure safe drinking water.
Description
Technical field
The present invention relates to water purification technology field more particularly to a kind of oxidation-absorbing synergic purifiers.
Background technique
The extensive preservation of these three elements of arsenic, iron, manganese is in all kinds of rock forming minerals of nature, and this three exists centainly
Symbiosis.Under the influence of specific geology, geochemistry, hydrogeologic condition and human factor, arsenic, iron, manganese can be from them
It is discharged into underground water in the mineral of preservation, forms high arsenic, high-speed rail, high manganese underground water.Contain for example, working as DOC in underground water
When measuring higher, cause iron and manganese oxides mineral that dissimilatory reduction occurs, iron and manganese oxides mineral reduction generates the Fe of solubilised state2+With
Mn2+, the arsenic for being adsorbed on iron and manganese oxides mineral surfaces is released immediately, results in high arsenic, high-speed rail, the height of strong reducing property
Manganese underground water.
Long-term intake high-arsenic underground water easily leads to Skin pigmentation, can lead to cardiovascular and cerebrovascular disease or even interior when serious
Internal organs official's canceration, such as lung cancer, kidney, bladder cancer.Iron and manganese in water also result in a variety of diseases such as diarrhea, failure of memory
Disease.Underground water will be greatly reduced its safety when containing High Concentration of Arsenic, iron as main drinking water and industrial water water source
Property, seriously affect the health and industrial and agricultural production of people.Therefore, for high arsenic, high-speed rail, high manganese underground water carry out repair with
Improvement work is particularly important and urgently with guarantee and industrial and agricultural production.
Currently, the removal for being directed to arsenic in water is common absorption method, oxidation and the precipitation method, membrane separation process, cation and anion exchange
Method etc. is maximally efficient and economic method using absorption method for family's water purification.But in the water quality item of strong reducing property
Under part, arsenic exists mostly in the form of the very strong As of migration (III) in water, reduces the arsenic removal efficiency of renovation agent.Therefore, needle
It to the high-arsenic underground water of strong reducing property, is used in combination with other oxidants, can preferably play the clean-up effect of adsorbent.Manganese
Sand and dissolved oxygen are the natural strong oxidizers being widely present, and the two synergistic effect can remove iron in underground water, pollution by manganese object,
The oxidation-reduction potential for improving water, is ideal high-speed rail, manganese groundwater treatment material.In numerous adsorbent materials, iron
Oxide has good adsorption effect to arsenic, and how to prepare large specific surface area and the uniform ferriferous oxide adsorbent of character is mesh
Preceding research hotspot.
Summary of the invention
In view of this, the present invention provides a kind of oxidation-absorbing synergic purifier, which is with dissolved oxygen and manganese sand
Oxidant improves the oxidation-reduction potential of water body, goes the harmful substances such as removing ferro in water, manganese；With powdered amorphous carbon nanowires and powder
Last shaped activated carbon is adsorbent, arsenic, iron, manganese harmful substance in further Adsorption water.The equipment can be used in purified treatment
The primary underground water inferior of high arsenic, high-speed rail, the high manganese of strong reducing property, ensures safe drinking water.
The present invention provides a kind of oxidation-absorbing synergic purifier, including self-priming dissolved oxygen acquisition equipment, rough filtering device
And device for deep cleaning, the self-priming dissolved oxygen acquisition equipment include the self priming pump being sequentially communicated, suction type air inhalator
With gas-water separation valve, the gas-water separation valve, rough filtering device and device for deep cleaning are sequentially communicated, and the self priming pump will be to be processed
Underground water be pumped into suction type air inhalator, the inside of the suction type air inhalator is opened up to be sucked through suction type air
