Embodiment 1

[0029] A novel high-content iron-manganese groundwater treatment process, including the following steps:

[0030] A. Install special activated carbon in No. 1 and No. 2 filters, install manganese sand in No. 3 filters;

[0031] B. Input the flocculant into the static tube mixer, and the water in the static tube mixer is fully mixed with the flocculant;

[0032] C. The water mixed with the flocculant enters the No. 1 filter for the first iron and manganese removal treatment;

[0033] D. The effluent from the No. 1 filter enters the storage tank, and its iron and manganese content is tested. When the content of ferromanganese is equal to or lower than 5mg / L, the water is directly sent to the No. 3 filter; if the content of ferromanganese is high At 5mg / L, pass the water through the static tube mixer again and add the flocculant to the No. 2 filter; after being processed by the No. 2 filter, it will be sent to the No. 3 filter;

[0034] E. The effluent of the No. 3 filter flows into the c...

Abstract

The invention provides a novel treatment process for underground water with high content of iron and manganese. Filtering is performed in a three-stage filtering manner including activated carbon filtering, activated carbon filtering and manganese sand filtering. The filter efficiency is high, and the effect is good. Compared with a traditional method, energy is saved, and consumption is reduced; modified bagasse activated carbon is adopted, raw materials are environment-friendly, renewable and low in cost and facilitate recovery of iron and manganese, and waste is turned into wealth.

Description

Technical field [0001] The present invention relates to the field of water treatment, in particular, to a novel high-content iron-manganese groundwater treatment process. Background technique [0002] The problem of excessively high iron and manganese content in basements in our country is common. The conventional contact oxidation filtration method can no longer meet the requirements of drinking water indicators, especially the water treatment process of groundwater with high iron and manganese content at the same time is a difficult Subject. [0003] Chinese invention patent CN101759314A discloses a process for treating water with high iron content and manganese. The process uses a two-time aeration oxidation treatment + flocculation + manganese sand solution for water treatment. The iron content of the treated water is ≤0.3mg / L, The manganese content is ≤0.1mg / L, which can meet the water quality requirements of the chemical water treatment system of the power plant. [0004] How...
