Abstract
The present invention is high manganese water purifying process, and relates to water treatment. The high manganese water purifying process includes the following steps: 1. adopting nickel net as filtering net; 2. adopting filtering material comprising diatomite and active carbon in the volume ratio of 2 to 1; and 3. accumulating the filtering material onto the filtering net to the thickness of 5-10 cm, applying positive voltage of 220 V to the filtering net and filtering underground water in the speed of 0.3-1.0 cu m/sq m.s, so as to eliminate manganese dioxide effectively. The process has low purifying cost and high manganese dioxide eliminating efficiency.
Description
Technical field
The present invention relates to a kind of water treatment method, particularly relate to a kind of high manganese water purifying process.
Background technology
Manganse Dioxide content is higher in the underground water of the northern area of China, it has been generally acknowledged that in the past it is harmless to human body, but it is a kind of potential carcinogens that Recent study is found Manganse Dioxide, therefore must find the low and effective purifying method of a kind of cost to handle high manganese water.
Summary of the invention
The objective of the invention is to overcome the existing inefficient shortcoming of high manganese water technology, improve by test, providing a kind of is filter screen with the nickel screen, and diatomite and gac are the low cost of filtrate, high efficiency high manganese water treatment method.
The objective of the invention is to be achieved through the following technical solutions:
A kind of high manganese water purifying process, this method may further comprise the steps:
(1) selecting nickel screen for use is filter screen;
(2) selecting diatomite and gac for use is filtrate, and diatomite and gac volume ratio are 2: 1;
(3) at first filtrate is deposited on the filter screen, thickness is 5～10cm, and nickel filter net is loaded 220V positive electricity, again with the underground water that extracts with the speed of 0.3～1.0 cubic metre of/square metre second by filtrate and filter screen, can effectively remove the Manganse Dioxide in the water.
Advantage of the present invention and effect are:
The present invention is filter screen with the nickel screen, and diatomite and gac are filtrate, and it is low that it purifies cost, Manganse Dioxide clearance rate height.
