產(chǎn)品簡(jiǎn)介:
鐵和錳在地下(井)水中幾乎同時(shí)曾在,水中含鐵量較高時(shí),水有鐵腥味,影響水的口感,作為造紙、紡織、印染、化工和皮革精致等生產(chǎn)用水,Will reduce the quality of products, including hot metal can make production equipment occurred rust, washing the clothes will appear yellow or brown stain, iron precipitate Fe2O3would grow iron bacteria, blocking the pipe, sometimes will appear red water. While the content of Mn in high water with high content of iron in the similar situation, such as the water color, flavor, smell, textile, papermaking, damage brewing, food and other industrial products quality, household appliances will pollute the brown or black,洗滌衣物會(huì)有微黑色或淺灰色斑漬。為此我國《生活飲用水衛(wèi)生標(biāo)準(zhǔn)》(GB5749-85)規(guī)定,鐵含量≤0.3㎎/L,錳含量≤0.1㎎/L,超過標(biāo)準(zhǔn)的原水須經(jīng)除鐵除錳處理。長(zhǎng)時(shí)間飲用含鐵含錳量過高的水還會(huì)嚴(yán)重影響身體健康,對(duì)生產(chǎn)設(shè)備腐蝕能力極強(qiáng)。 處理方法:
The contents of iron and manganese in high water are generally used in catalyst ( such as manganese sand ) under the effect of dissolved Fe two or two valence manganese were oxidized into insoluble ferric or tetravalent manganese compounds,利用錳砂過濾器的反沖洗功能達(dá)到去除凈化的目的。4Fe2++O2+10H2O 4Fe(OH)3+8H2Mn2++O2+2H2O 2MnO2+4H+技術(shù)要求:
用于地下水除鐵除錳的天然錳砂,The forms of manganese in manganese oxide mainly. Manganese content ( MnO2) should not be less than35% of natural manganese sand filter, which can be used for groundwater in addition to iron, and can also be used for groundwater removal of manganese; manganese content is 20% ~30% of natural manganese sand filter, should be used only for iron removal of groundwater;含錳量小于20%的錳礦砂則不宜采用;宜優(yōu)先采用經(jīng)過科學(xué)試驗(yàn)或生產(chǎn)使用證明能獲得良好除鐵和除錳效果的天然錳砂品種作濾料。??
