Problems solved by technology

However, the disadvantage of natural filter material filtration is that the operation is more complicated, and regular washing and backwashing are required to remove the colloid adsorbed on the sand and gravel filter material to restore the filtration capacity, and the washing time is long and the washing frequency is short. Periodically replac...

Embodiment Construction

[0024] Below in conjunction with the accompanying drawings ( Figure 1-Figure 2 ) to describe the present invention.

[0025] Description of the filtration function of the membrane element: The membrane element used for filtration is an ultrafiltration membrane with a porous structure. This is called the physical retention of the membrane.

[0026] Membrane elements include tubular membrane elements, plate membrane elements, and hollow fiber membrane elements, among others. The membrane module includes a combination of multiple membrane elements, or a combination of a single membrane element and other structural members.

[0027] The core technology of the present invention is ultrafiltration membrane, and the treatment principle of ultrafiltration membrane method includes two aspects. One is to use the physical interception of the membrane to physically separate the solvent from the solute or particles. Water, dissolved salts and other electrolytes are tiny particles. It c...

Abstract

The invention provides a membrane processing system for ground water containing excessive ferro manganese ions and a method thereof. The invention is characterized in that the membrane processing system comprises an aeration pond and a membrane assembly, wherein the membrane assembly is arranged inside the aeration pond, and an inner cavity of the membrane assembly is communicated with a suction pump positioned outside the aeration pond through a water outlet pipeline. The excessive ferro manganese ions in the ground water mean that the ferric ions or manganese ions or both contained in the water are incapable of meeting the indexes of GB5749-2006 Sanitary Standard for Drinking Water. The ground water treated by the system and method has stable water quality and exceeds the indexes of GB5749-2006 Sanitary Standard for Drinking Water. The system and the method are suitable for areas where the ferro and manganese content in the ground water is high and water treatment reclamation areas. The system and the method are worthy of generalization and application.

Description

technical field [0001] The invention relates to groundwater treatment, in particular to a membrane treatment system and method for groundwater whose iron and manganese ions exceed the standard. Indicators of Water Sanitation Standard GB5749-2006. Background technique [0002] Iron and manganese-containing groundwater has been infiltrated and filtered for a long time in the formation, and it contains almost no suspended solids and no dissolved oxygen. Generally, the water quality is clear and transparent. When the iron and manganese-containing groundwater is pumped to the ground, the oxygen in the air is quickly dissolved in the water, and the low-valent iron and manganese ions in the water react with oxygen to generate high-valent ions, making the water turbid or red. [0003] In the removal of iron and manganese from groundwater, the general process adopts a two-step method: the first step is to dissolve oxygen in raw water to oxidize low-valent iron and manganese ions int...
