specific Embodiment approach 1

[0030] Specific implementation mode one: combine figure 1 , This embodiment is a treatment method for biologically synchronous removal of high iron and high manganese in underground drinking water under low temperature conditions, which is specifically completed according to the following steps:

[0031] 1. Loading filter material: Add carbonized rice husk particles and support material I to the 1# filter column (12) of the biological synchronous removal of high iron and high manganese device from top to bottom to obtain the filter material layer and support layer I. The thickness of material layer is 150cm~180cm, and the thickness of support layer I is 8cm~10cm. Add sterilizing activated carbon and support material II to 2# filter column (23) to obtain adsorption filter material layer and support layer II. The thickness of the filter material layer is 120cm-180cm, and the thickness of the supporting layer II is 8cm-10cm;

[0032] 2. Start-up phase:

specific Embodiment approach 2

[0051] Specific implementation mode two: combination figure 1The difference between this embodiment and the specific embodiment one is: the bio-synchronous removal of high-iron and high-manganese device described in step one is composed of the aeration tank (1), the 1# filter column inlet water submersible pump (2), and the 1# filter Column water inlet control valve Ⅰ (3), 1# filter column water inlet flow meter (4), 1# filter column water inlet control valve Ⅱ (5), bacteria solution pool (6), bacteria solution inlet submersible pump (7 ), bacteria solution inlet control valve Ⅰ (8), bacteria solution inlet water flowmeter (9), bacteria solution water inlet control valve II (10), bacteria solution water outlet control valve (11), 1# filter column (12) , 1# filter column water inlet (13), 1# filter column overflow port (14), 1# filter column sampling port (15), 1# filter column intake port (16), 1# filter column outlet ( 17), 1# filter column water outlet control valve (18), i...

specific Embodiment approach 3

[0052] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the supporting material I described in step 1 is a mixture of pebbles and manganese sand, and the pebbles in the mixture of pebbles and manganese sand are used as supports , manganese sand as filler. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a treating method of biologically and synchronously removing high iron and manganese in underground drinking water under the low-temperature condition, relates to a treating method of high iron and manganese in underground water in a severe cold area and aims at solving the problems of the traditional treating method of the underground water in the severe cold area of low efficiency in removing iron and manganese and high removing cost. The treating method comprises the following steps: 1, loading a filter material; 2, starting; and 3, performing a stable operation phase, namely finishing treatment of biologically and synchronously removing high iron and manganese in the underground drinking water under the condition of low temperature. The treating method has the advantages that 1, with carbonized rice hull particles as a bio-immobilized material, reasonable and effective resource utilization is realized; and 2, iron and manganese are rapidly and synchronously removed, and the removing efficiency is remarkable and stable. According to the treating method disclosed by the invention, an activated carbon filter column is capable of effectively treating residual iron and manganese oxidizing bacteria after biological filter column treatment of the carbonized rice hull particles, and the safety of the drinking water is guaranteed. The treating method is mainly used for treatment of biologically and synchronously removing high iron and manganese in the underground drinking water under the low-temperature condition.

Description

technical field [0001] The invention relates to a method for treating high-iron and high-manganese levels in underground water in severe cold regions. Background technique [0002] The Sanjiang-Songliao Plain is the second largest groundwater enrichment area in my country. The exploitable groundwater resources are 30.64 billion cubic meters per year, accounting for 8.68% of the total exploitable groundwater resources in the country. Its scope includes most of Heilongjiang Province and Jilin Province. In severe cold regions such as the west, the west of Liaoning Province and the northeast of the Inner Mongolia Autonomous Region, in addition to the simple terrain conditions in the above-mentioned areas, the groundwater is shallow and stable in distribution, so that the groundwater resources in this area have great potential for exploitation, and it is also the promotion of regional economic development and protection. Important natural resources for people's production and life....
