Description

Field of the Invention The present invention relates to an apparatus and a method of using a decontamination apparatus for improving the soil of a golf course,

Field of the Invention The present invention relates to an apparatus for acid correction or salt (mineral) conditioning and soil improvement of an acidic or alkaline grass soil formed in a golf course, and a method for improving the same.

Cultivars, Cultivation, Establishment, Drainage, Drainage, etc. are factors that affect the maintenance of grass grasses in commercial facilities such as golf course, playground, soccer field, park, Mowing, Traffic, Irrigation, Fertilizers, Pesticides, and so on.

However, in the case of grass laid at a commercial facility such as the golf course described above, it is a reality that it is exposed to severe stress due to frequent mowing, an artificial pressurization and drainage failure, and thus, the pest insect damage and weakening of immunity are extreme.

This is even more problematic when commercial facilities such as golf courses are exposed to harsh environments.

For example, if a golf course is located adjacent to a beach that has a direct influence on salt accumulation such as Na ⁺ ions, Cl ^- ions and sea breezes and seawater, or is located in nutrient-poor soil, or is acidic or alkaline If it is located on a barren soil, or if it is formed in a terrain with severe changes in water temperature and precipitation such as cold weather, the amount of pesticide / fertilizer as well as the amount of lawn water is inevitably increased.

On the other hand, fertilizer can be divided into maintenance fertilizer used for promoting the growth of lawn and orthodontic fertilizer for removing salt from the soil and adjusting pH.

However, as described above, since a large amount of pesticide / fertilizer can only be used for maintaining the grass of the golf course, accumulation of salt in the grass soil is caused, and therefore, about 20 ~ 60% of the total fertilizer is used A vicious cycle continues.

As described above, this vicious cycle becomes even worse when the golf course is exposed to a harsh environment.

For example, in the case of soil in Jeju Island, Korea, the alkaline soil is mostly pH 8.0 or higher. Since the pH of grass soil suitable for the growth of grass is about 5 ~ 6.5, orthodontic fertilizer for pH calibration is used periodically and fertilizer for orthodontic fertilizer is in the form of compound fertilizer. The vicious circle is repeated.

In this vicious cycle, frequent spraying of pesticides and fertilizers must be completed through the supply of grass water, so that even a vicious cycle in which essential nutrients in lawn soils are eluted due to the increase of grass water supply and the supply is increased.

Moreover, this problem is weighted because the pH of the soil has a very important influence on the growth of turf.

For example, if the pH of the soil is alkaline, the effective amount to absorb the nutrients of the trace elements (Fe, Mn, and Zn) is low. If the pH of the soil is acidic, (Na), phosphorus (P) ion and potassium (K) ionic salts, which are called Ca ^{2 +} ions and Mg ^{2 +} ions, There is an easy problem.

Since it is a known technique to maintain the pH of the soil at a pH range of 5 to 7.0 suitable for turf growth, a large amount of orthodontic fertilizer has conventionally been used to control the pH of the soil. The problem of using a large amount of orthodontic fertilizer is as described above.

On the other hand, in terms of the supply of grass water, the water quality of grass water is no longer taken into consideration once the necessary capacity is secured once the supplyable water source is limited according to the geographical conditions where commercial facilities such as golf course are located.

In other words, in the case of conventional commercial lawns, the lawn is managed only on the basis of pesticides and fertilizers, provided that abundant lawn water is supplied. Therefore, overuse of pesticides and fertilizers is inevitable in conventional commercial lawn management. In addition, environmental problems such as water pollution caused by elution of non-point pollution sources are caused as compared with salt pollution.

In addition, as described above, it is assumed that a large amount of grass water is needed. Therefore, there is a problem in that the grass grows when the source water of the source such as the watery season is exhausted, the economic problem is caused by supplying a large amount of grass water, It is a matter of course that the problem of pollution is added.

The problem of such conventional grass growth is due to the fundamental paradigm that grass growth approaches "soil-centered".

That is, as described above, all the above problems arise from the conventional paradigm which adopts a method of adding pesticide and fertilizer to a huge amount of grass water for physical / chemical improvement of grass soil, have.

In view of the conventional techniques, it is necessary to improve the soil through pesticides, fertilizers or nutritional supplements to improve the environment suitable for the growth of lawns, to secure the stability of prevention, and to suggest a liquid fertilizer or a soil adsorbent Only.

Specifically, the application No. 10-2004-0099460 proposes a method of fertilizing a pH-correcting solution of an alkaline soil in the form of a liquid fertilizer to which ferrous sulfate, wood vinegar and water are added, 10-2006-0123677 proposes a soil improvement agent for lawn soil composed of a bottom ash and a sandy soil to improve the physical properties of the soil to improve the growth of the lawn. In Application No. 10-2001-0052659, And a new grass soil composition to maximize the growth of grass roots.

In addition, Application No. 10-2005-0017414 discloses a method for improving the absorption of nutrients in the soil of grass roots by adding a puddle (pumice) among the constituents of the soil where lawn grows and minimizing organic and inorganic components leached from the soil layer Soil amendment was proposed.

In addition, Application No. 10-2004-0111827, Application No. 10-2001-0050028, Application No. 10-2002-0085265, Application No. 10-2002-0000361 disclose a method for promoting and maintaining grass growth Suggesting methods for the production and utilization of manure and compost such as using sewage sludge and iron by-products, using organic compost, or using plant juice.

In addition, Application No. 10-2007-0101772 proposes a method of using zero valence iron as a follow-up concept for the abuse of pesticides and fertilizers to remove pesticides and fertilizer components contained in drainage.

In sum, the prior art focuses on controlling artificially direct or indirect optimal conditions to maintain soil nutrient supply to turf for turf growth. In other words, we have developed a liquid fertilizer to make the grass roots contain a lot of nutrients, to improve the soil by using a soil improvement agent, to maximize the fertilizer's effectiveness, or to propose a natural fertilizer or compound fertilizer with excellent effect.

However, in plants such as grasses, water (water) is contained in 70 to 80% and is a main factor of plant formation. In addition, water is involved in the photosynthetic mechanism in plants, is a solvent and a catalyst for metabolism, plays an important role in nutrient absorption pathway and growth regulation.

In other words, the existing soil-based paradigm overlooked the fact that grass water was only water that could be supplied infinitely, and had a very large effect on the growth of grass.

Especially, in the case of golf course, grass water is an essential element for its existence, but if it satisfies the prerequisite for the construction of the golf course in advance, it is not considered after that.

Accordingly, there is no proposed invention specifically regarding the effect of the amount of lawn water for lawn growth and the quality of the water quality of lawn water for commercial facilities such as a golf course on grass and lawn soil.

On the other hand, Application No. 10-2009-7000648 discloses an irrigation system having a separation apparatus for treating salt by receiving pre-treatment water, and a supply unit for supplying it to the soil. However, this prior art is not an idea of improving the soil, but merely supplying appropriate irrigation water to the plant that is growing only, so that it can not reach the improvement of the soil, and as described above, the problems such as the economic problem and the problem of leaching of non- .

In addition, in the paper entitled "Experience with full-scale eletrodialysis for nitrate and hardness removal, Desalination, 117, 173-180 (1998.)" published in 1998, the pH of the pre- This decontamination method is not only a very general method but also has nothing to say about the alkalization of the soil and the dissolution of the soil caused by the use of irrigation water such as pH 7.5, Considering this, it is a technology related to the supply of irrigation water rather than improvement of the soil, and may cause more problems in the improvement of the soil.

Accordingly, the present invention proposes an apparatus and method for maintaining an optimum lawn.

In other words, it is a fusion model of grass water management and soil management through control of pH and decontamination (Inorganic minerals removal) of grass water suitable for grass growth, away from the paradigm of "soil management" model through conventional pesticide and fertilizer .

The present invention also provides an intelligent soil remediation apparatus and method for detecting water quality of a water source and soil quality of soil in real time to minimize the amount of necessary grass water and pesticide / fertilizer while enabling optimum lawn care.

In order to solve the above-mentioned problems, the present invention provides a water treatment system comprising: a pretreatment unit (220) for supplying raw water from a water source unit (210) to a pretreatment; A main processing unit 230 including a decontamination apparatus to which the pretreated water is supplied and decontaminated; A supply unit 240 for supplying the decontaminated main treatment water to the soil 430 as turf water 120; A water treatment sensor unit 310 for sensing water quality of the water source unit 210; A water treatment control unit (320) for controlling the pre-treatment unit (220) to pre-treat the raw water when the sensed water quality does not meet predetermined water quality standards; And a soil sensor unit 330 for sensing the soil of the soil 430. The water treatment control unit 320 controls the pretreatment water pretreatment water if the sensed soil does not meet predetermined soil quality standards And controlling the main processing unit (230) to process the soil to improve the soil of the golf course.

The water treatment sensor unit 310 senses at least one of pH, electrical conductivity, total dissolved solids (TDS), dissolved oxygen (DO) and turbidity of raw water of the water source unit 210 desirable.

In addition, the Soil sensor unit 330 pH, conductivity, total dissolved solids (TDS), dissolved oxygen (DO), sodium adsorption ratio (SAR), base exchange capacity (CEC) of the soil (430), Cl ^- Ions and HCO ₃ ^- ions in real time.

It is preferable that the pretreatment unit 220 performs pretreatment of the raw water by at least one of a chemical injection process, a coagulated sedimentation process, a flotation separation process, a membrane filtration process, a media filtering process, and a disinfection process.

In addition, the main processing unit 230 preferably performs the main treatment and the decontamination treatment of the pretreated water by at least one of a nanofiltration process, a reverse osmosis process, an ion exchange process, an electrodialysis process, and an evaporation process.

The total dissolved solids (TDS) of the grass water 120 may be in the range of 5 to 6.5, or the electric conductivity of the grass water 120 may be 10 to 200 μs / 5 to 150 mg / L.

In addition, the soil 430 is a soil of a golf course, and the soil of the grass grows, and the raw water of the water source 210 is preferably a pond water.

In order to solve the above-mentioned problems, the present invention provides a method of detecting water quality, comprising the steps of: (a) detecting a water quality of raw water of a water source unit 210 by a water treatment sensor unit; (b) when the sensed water quality does not meet predetermined water quality standards, the water treatment control unit 320 controls the pre-treatment unit 220 so that raw water is introduced into the pretreatment unit 220 and is pretreated; (c) detecting the soil of the soil 430 by the soil sensor unit 330; (d) If the detected soil does not correspond to a preset soil criterion, the water treatment control unit 320 controls the main treatment unit 230 so that the pretreated water flows into the main treatment unit 230 and is subjected to decontamination treatment step; (e) supplying the treated water to the soil (430) as turf water (120).

First, in the management of lawns in commercial facilities, especially in the management of golf course lawns, we actively cope with changes in seasonal climate such as rainfall, temperature difference, heat, and cold weather to maintain optimum lawn growth with intelligence, Can be monitored.

Secondly, it is possible to intelligently control / supply grass water to maintain the grassy soil where the best lawn grows, thereby reducing the amount of unnecessary orthodontic fertilizer used and the amount of lawn water. That is, by maintaining the growth of healthy turf, the amount of orthodontic fertilizer and maintenance fertilizer can be reduced, which can reduce the total fertilizer usage by about 20 to 60%. In addition, the amount of lawn water is proportional to the amount of fertilizer, and the amount of lawn water can be reduced by 10 to 30% because it is affected by the growth condition of lawn.

Third, it can sustain environmentally friendly facilities by saving pesticide and fertilizer and grass water. In particular, it is possible to maintain the course of the golf course in an eco-friendly way, and it is possible to save the operation cost of the golf course, and the groundwater and the soil pollution can be drastically reduced through reduction of the nonpoint pollution source. In addition, secondary management problems such as salt stress and fond pollution can be solved compared with the abuse and inappropriate use of pesticide and fertilizer and grass water.

FIG. 2 is a conventional apparatus according to the related art, and FIG. 3 is a view for explaining a soil improvement result adjacent to a beach, as a utility apparatus according to the present invention.

It should be understood that the term " pond " described below is not limited to the fond of the golf course, but is a concept that encompasses storage facilities such as a reservoir in a golf course and a water hazard.

The term "grass water" described below is not limited to the irrigation water required for the growth of silk grasses, but should be understood as a concept covering all irrigation water necessary for the growth of any plant in a golf course.

Hereinafter, the soil remediation apparatus and method according to the present invention will be described in detail with reference to the drawings.

1. Description of soil improvement apparatus

The soil remedying apparatus according to the present invention includes a water source unit 210, a pretreatment unit 220, a main treatment unit 230 and a supply unit 240, and further includes a control unit 300 for sensing water quality or soil quality and controlling the apparatus .

The soil (430) applied to the soil remediation apparatus according to the present invention is a soil in which grass grows at a golf course. Also, it is preferable that the water source unit 210 in which the raw water to be used as the grass water is stored is a pond water.

The pretreatment unit 220 receives raw water from the water source unit 210 and performs pretreatment.

The pretreatment unit 220 is mainly used for removing particulate matter, microorganisms, and organic matter. Any process can be performed to accomplish this. For example, it may be performed by performing at least one of a chemical injection process, a mixed flocculation and sedimentation process, a float separation process, a membrane filtration process, a filter material filtration process, and a disinfection process.

The main processing unit 230 receives the pretreatment water pretreated from the pretreatment unit 220 and performs a decontamination treatment as the main treatment.

The main processing unit 230 mainly removes dissolved inorganic salts. To this end, a decontamination apparatus (not shown) is provided. Any of the processes for carrying out the decontamination treatment may be performed, for example, by performing at least one of a nanofiltration process, a reverse osmosis process, an ion exchange process, an electrodialysis process, and a vaporization process.

The decontaminated main process water is supplied to the supply unit 240 as turf water. The supply unit 240 supplies the soil 430 to the grass 420 or the like.

The control unit 300 includes a water treatment sensor unit 310, a water treatment control unit 320, and a soil sensor unit 330.

The water treatment sensor unit 310 senses the water quality of the water source unit 210 in real time. For example, the water quality standard sensed by the water treatment sensor unit 310 may be at least one of pH, electrical conductivity, total dissolved solids (TDS), dissolved oxygen (DO) and turbidity of raw water.

The soil sensor 330 senses the soil of the soil 430 in real time. For example, the soil criteria that the soil sensor 330 senses include pH, electrical conductivity, total dissolved solids (TDS), dissolved oxygen (DO), sodium adsorption ratio (SAR) CEC), Cl ^- ions and HCO ₃ ^- ions in real time.

The water treatment control unit 320 may control the operation of the pretreatment unit 220 and the main treatment unit 230 according to the water quality sensed by the water treatment sensor unit 310 and the soil sensed by the soil sensor unit 330.

When the water quality of the raw water 210 detected by the water treatment sensor unit 310 does not meet predetermined water quality standards, the water treatment control unit 320 controls the pre-treatment unit 220 to remove raw water from the water source unit 210 So that they are pre-processed.

If the soil quality of the soil 430 detected by the soil sensor 330 does not meet the predetermined soil quality standard, the water treatment control unit 320 controls the main treatment unit 230 to perform pre-treatment in the pre- Let the water be decontaminated.

That is, the pretreatment of the pretreatment unit 220 depends on the quality of the raw water of the water source unit 210, and the decontamination treatment of the main treatment unit 230 depends on the soil of the soil 430.

Through this, the decontaminated grass water suitable for the soil of the soil 430 can be supplied.

In addition, the properties of the finally supplied grass water will be somewhat different depending on the soil of the soil 430. However, in consideration of the general conditions under which the grass 420 grows, the pH of the grass water will be from 5 to 6.5, the electrical conductivity thereof will be 10-200 占 / / cm, and the total dissolved It is preferable that the solid content (TDS) is 5 to 150 mg / L.

2. Description of soil improvement method

The soil improvement method according to the present invention will be described.

First, the water treatment sensor unit 310 senses the quality of raw water of the water source unit 210 in real time. If the sensed water quality does not meet the predetermined water quality standard, the water treatment control unit 320 controls the pre-treatment unit 220 so that raw water will be introduced into the pretreatment unit 220 and be pretreated.

Meanwhile, at the same time, the soil sensor unit 330 detects the soil of the soil 430 in real time. If the detected soil does not meet the prescribed soil quality standard, the water treatment control unit 320 controls the main treatment unit 230 so that the pretreated water flows into the main treatment unit 230 and decontaminated.

Thus, the main treated water which has been suitably pretreated and decontaminated according to the water quality and the soil is supplied to the soil 430 as the grass water 120.

3. Explanation of soil improvement results

Referring to FIGS. 2 and 3, the soil improvement result of a golf course adjacent to the beach is compared with the prior art. 2 and 3 are conceptual diagrams illustrating a conventional apparatus for managing a golf course lawn, and FIG. 2 illustrates a conventional apparatus according to the related art. FIG. 3 illustrates a conventional apparatus 410 'according to the present invention. Respectively.

When looking at the soil in which the grass grows, it is generally considered that undesirable salts are accumulated in the growth of grass leaves and grass roots around the soil particles, thereby deteriorating the air permeability of air and water, thereby causing a poor drainage phenomenon.

Therefore, it is necessary to remove unnecessary salts such as Na ⁺ ions and Cl ^- ions adsorbed on the soil particles.

2, conventionally, fertilizer 10 such as calcium sulfate (CaSO ₄ ), calcium carbonate (CaCO ₃ ) or the like is replaced with grass water 20 to replace Na ⁺ ions with Ca ^{2 +} ions Have been supplied together.

However, as shown in the figure, in the case of a golf course adjacent to the beach, grass water 20 according to the prior art generally includes unnecessary inorganic salts such as Na ⁺ ions and Cl ^- ions.

Thus, this not only adversely affects the lawn 420, but also continues to accumulate in the soil, resulting in the same result as the soil 430 shown in Fig.

Fig. 3 shows an apparatus according to the present invention.

According to the present invention, the turf water 120 is subjected to pretreatment and main treatment, that is, decontamination treatment.

Accordingly, as shown in FIG. 3, a large amount of Na ⁺ ions, Cl ^- ions, S ^- ions and HCO ₃ ^- ions are removed from the turf water 120, so that the pH range can be maintained at 5 to 7. This is a significant difference from the conventional grass water 20 having a pH of 7 to 8.5. This can significantly reduce the amount of orthodontic fertilizer (A) and unnecessary amount of lawn water (B).

Also, the use amount of the fertilizer for maintenance can be reduced from the mid- to long-term viewpoint.

In addition, as shown by the soil 430 in FIG. 3, Na ⁺ ions having a high hydration degree can be continuously removed to ensure air permeability, drainage, bubbling and the like.

Although the preferred embodiments of the present invention have been described, the present invention is not limited to the specific embodiments described above. It will be apparent to those skilled in the art that numerous modifications and variations can be made in the present invention without departing from the spirit or scope of the appended claims. And equivalents should also be considered to be within the scope of the present invention.
