Abstract
The invention discloses a deep well water treatment technology and belongs to the technical field of water treatment. The deep well water treatment technology solves the problem that the existing deep well water treatment technology has a low treatment capability and poor product water quality. The deep well water treatment technology comprises the following steps of feeding raw water into a water adjustment tank, wherein an aerator pipe and a membrane fine-bubble aerator are installed in the water adjustment tank, carrying out aeration when a water level in the water adjustment tank has the height of 2.5m, stopping water feeding when a water level in the water adjustment tank has the height of 3.3m, sequentially carrying out aeration for 20 to 40min so that ferrous iron in the raw water is oxidized into ferric iron by aeration, feeding the treated water into a filter pressure pump, adding a flocculant into the treated water, carrying out pressure filtration, carrying out reverse osmosis desalination by a filter with quartz sand and manganese sand as mediums, and feeding the treated water into a clean water tank. The deep well water treatment technology can effectively solve the problem that ferrous iron ion content, sulfate ion content and calcium ion content of raw water exceed standards. Water treated by the deep well water treatment technology can satisfy national drinking water standards.
Description
Technical field
The invention belongs to water-treatment technology field, be specifically related to a kind of phreatic water treatment process.
Background technology
At present, traditional phreatic water treatment process is that deep-well water supply well water enters equalizing tank, the strainer force (forcing) pump absorbs water from equalizing tank, enter the pressure type quartz filter after mixing in water pump with former water through dosing, remove the turbidity in water, the cartridge filter of strainer water outlet before directly into follow-up reverse osmosis equipment adds Scale inhibitors and ensures that reverse osmosis system normally moves on the cartridge filter water inlet pipe, and the cartridge filter water outlet enters reverse osmosis body equipment and processed after the high-pressure pump pressurization.
But, deterioration along with environment, when total hardness, calcium, magnesium, vitriol, the total dissolved solid occurred in deep well water quality exceeds standard, traditional treatment process and equipment just can not meet the needs of processing power, and the water after non-processor can't reach national drinking water standard.
Summary of the invention
The present invention is that the processing power in order to solve existing phreatic water treatment process existence is low, and the water quality after processing is difficult to reach the problem of national drinking water standard, and a kind of phreatic water treatment process is provided.
The present invention is achieved by the following technical solutions:
A kind of phreatic water treatment process comprises the following steps:
(1) the deep-well water supply well comes former water to enter balancing tank, aerated conduit and diaphragm porous aerator are installed in equalizing tank, when in equalizing tank, water level reaches 2.5m, start aeration, until water level is while reaching equalizing tank high-water 3.3m, stop into water, continue aeration 20-40min, the ferrous iron in former water becomes ferric iron by the aeration oxidation conversion;
(2) water after equalizing tank is processed is sent into to the strainer force (forcing) pump, and after adding after flocculation agent and carrying out the filtering under pressure processing;
(3) water after filtering under pressure is processed is carried out to the reverse osmosis desalination processing, use quartz sand and manganese sand medium filter during processing, thoroughly to remove the ferrous ion in water;
(4) water after more medium filter is processed is sent into clean water basin, gets final product.
The present invention can effectively process the problem that the ferrous ion, sulfate ion and the calcium ion that contain in former water exceed standard, water quality after processing can reach national drinking water standard, and only need on the conventional process Equipment Foundations, simply transform, being easy to promote, cost is low.
Embodiment
Below in conjunction with embodiment, the present invention will be further described.
In August, 2011, the Shanxi coal Si He of group ore deposit phreatic water is carried out to water examination, find that the ferrous ion in former water disturbs the Scale inhibitors normal function, make it can not bring into play due effect, cause calcium sulfate, sal epsom fouling.
Adopt in by the end of August, 2011 the phreatic water treatment process to be processed, comprise the following steps:
(1) the deep-well water supply well comes former water to enter balancing tank, aerated conduit and diaphragm porous aerator are installed in equalizing tank, when in equalizing tank, water level reaches 2.5m, start aeration, until water level is while reaching equalizing tank high-water 3.3m, stop into water, continue aeration 20-40min, the ferrous iron in former water becomes ferric iron by the aeration oxidation conversion;
(2) water after equalizing tank is processed is sent into to the strainer force (forcing) pump, and after adding after flocculation agent and carrying out the filtering under pressure processing;
(3) water after filtering under pressure is processed is carried out to the reverse osmosis desalination processing, use quartz sand and manganese sand medium filter during processing, thoroughly to remove the ferrous ion in water;
(4) water after more medium filter is processed is sent into clean water basin, gets final product.
Wherein, the product water yield: Q=100m after reverse-osmosis treated
3/ h;
Former water requirement: Q
1=135m
3/ h;
The dense water yield of the saliferous that treatment station per hour discharges: Q
2=35m
3/ h.
Water quality is measured, be the results are shown in Table 1
| Ion | Former water Mg/L | Product water Mg/L | Dense water Mg/L |
| Ca | 651.0 | 119.9 | 224.4 |
| Mg | 176.0 | 20.1 | 643.8 |
| Na | 109.0 | 53.4 | 275.8 |
