Description

A equipment movable for the nutrients concentration and concentrate recovery using press device}

The present invention relates to a nutrient concentrate and concentrated water recovery apparatus, and more specifically, to concentrate nutrients (phosphorus, nitrogen) present in low concentrations, such as in general lakes or rivers, and easily recover the concentrated nutrients in the concentrated media by a compression method In addition, the present invention relates to a nutrient concentrate and concentrated water recovery device that can be moved to other areas of appeal or rivers.

In general, nutrients (phosphorus, nitrogen) increase when organic substances such as living sewage, industrial wastewater, and animal wastes enter the water in aquatic ecosystems such as rivers and lakes. As the nutrients increase, the nutrient cycle speeds up, and the amount of photosynthesis of algae also increases rapidly. As a result, the growth and reproduction progress very rapidly, leading to mass multiplication. This is called eutrophication.

When eutrophication occurs in rivers, seas, lakes, and the like, microorganisms decompose organic matters and grow and reproduce, causing red tide or green algae.

In other words, when organic salts such as nitrite, nitrate, ammonia, phosphate and silicate flow into the rivers, seas and lakes, nutrients (nitrogen, phosphorus) are released into the water. Such nutrient-rich water is phytoplankton Will grow and multiply rapidly, leading to red tide (or algae).

Since these large quantities of phytoplankton consume large amounts of oxygen, they suffocate fish and other aquatic organisms, disrupting the aquatic ecosystem, so eutrophicated water becomes dead water that generates odors and toxic substances from algae and is no longer available. Loss of value.

And rotting organics again and again release nutrients into the water, sustaining nutrient-rich eutrophic conditions, so it takes years to normalize the loss from eutrophication.

In addition, as the continuous inflow of plant wastewater, domestic wastewater, and fertilizer components into lakes and rivers, the progress of eutrophication is getting faster, and urgent countermeasures are required.

In addition, it does not cause water pollution because it can concentrate and fertilize nutrients in the field appealing water at the time of appealing greenery (vegetation restoration) in a water source protection area or equivalent area where chemical fertilizers or organic fertilizers cannot be used.

In order to solve these problems, the applicant has proposed a nutrient concentration and recovery apparatus in Korean Patent Publication No. 10-0878378.
