Produces the brine from which NaCl is contained in the brine.

1. The process of removing NaCl by electrodialysis apparatus

In the present invention, the removal of NaCl contained in the brine by the electrodialysis apparatus 3 is performed by separating the ionic solutes by membrane permeation using the potential difference of the direct current power as a driving force. The monovalent cation selective exchange diaphragm 9 selectively transmits a monovalent cation having a fixed negative charge, and the monovalent anion selective exchange diaphragm 8 has a fixed static charge. An ion exchange membrane is used which selectively permeates monovalent anions.

The electrodialysis apparatus 3 suppresses scale troubles and improves the NaCl removal efficiency while increasing the limit current density to improve the treatment efficiency. The cation selective exchange diaphragm 9 is alternately arranged in a row between the anode 4 and the cathode 5, and the anode 4 and the cathode of the anode chamber 6 at both ends are arranged. While applying the direct current to the cathode 5 of the chamber 7 from the rectifier, the water supplied to the water storage tank 1 is supplied to the desalination chamber 10 by the water transport pump 2 so that the salt concentration is 400. The NaCl is removed in the range of ~ 800 mg / l while some are returned to the water storage tank (1), and the desalted water is returned to the solenoid valve (ⓢ) by an electric conductivity indicating switch (ECIS). The concentrated brine of the concentrated brine reservoir 12 in the salt concentration chamber 11 When the chlorine is supplied to the salt concentration chamber 11 by the brine transfer pump 13 and circulated to the concentrated brine storage tank 12, Na ⁺ ions in the brine penetrate the monovalent cation selective exchange diaphragm 9 by electric attraction to the cathode. (5) is moved to the salt concentration chamber (11), Cl ⁻ ions are passed ^{through the} monovalent anion selective exchange diaphragm (8) to the salt concentration chamber (11) on the anode side 4 to remove NaCl. The concentrated brine concentrated in the brine concentration of 18 ~ 20 ° Be of the concentrated brine reservoir 12 is sent to the salt manufacturing process by operating the solenoid valve (ⓢ) by the BME (Baume indicating switch).

In this case, the electrical conductivity is an index indicating the degree of conductivity of the aqueous solution, and the salt concentration in water is a unit. The unit is S / m (Siemens / m) corresponding to the inverse of the electrical resistivity of the aqueous solution. The relationship between (EC) and soluble salts (TSS) in water is shown in the following equation ③.

TSS (ppm) = 640 X EC (mS / cm). … … … … … … … … … … … … … … … … … … ③

 The electrodialysis apparatus 3 preferably increases the current density as much as possible within the range below the limit current density in order to increase the processing performance. However, the limit current density is proportional to the salt concentration and is diffused.

In order to improve electrodialysis efficiency and to suppress scale trouble by increasing the amount of current passing by increasing the limit current density in the electrodialysis apparatus 3, the flow rate supplied to the desalination chamber 10 is the membrane surface linear velocity. The brine from which NaCl is removed in the range of 10-30 cm / sec is returned to the brine storage tank 1, and the flow rate of the concentrated brine supplied to the salt concentration chamber 11 has a membrane surface velocity of 1 to 3 cm /. Concentrated brine is returned to the concentrated brine reservoir 12 so that the second range is maintained.

Since scales are generated in the ion exchange diaphragm of the electrodialysis apparatus 3 and the treatment efficiency may be reduced due to fouling of the membrane, CaSO ₄ , CaCO ₃ , SrSO ₄ ... In order to suppress the generation of scale as much as possible, an ion exchange diaphragm is used, in which divalent or more ionic materials are poorly permeable and selectively transmit only monovalent ionic materials.

After mixing for 20-30 minutes at -5 RPM, it is sent to the aging machine 25 by the aging machine supply conveyor 24.

In the case of making fast-acting soil, 0.1 to 0.2 parts of one type of nitrogen fertilizer from urea, ammonium nitrate or ammonium sulfate per 100 parts of mature compost, Calcium superphosphate, 0.1 to 0.5 parts of one type of phosphate fertilizer (Double superphosphate, Fused phosphate fertilizer or Calcined phosphate), Potassium chloride, Potassium carbonate or Potassium sulfate ) 0.1-0.5 parts of one kind of potassium (K) fertilizer are supplied together.

At this time, the mixing amount of the fertilizer components of nitrogen, phosphoric acid, potassium is preferably adjusted according to the content of the components of the mature compost and the type of crop. Moreover, when acidity is strong, it is necessary to inject | pour lime and adjust pH.

2. Aging process

When the mixture in the mixer 22 is supplied to the aging machine 25, the mixture is aged for 1 to 3 times a day with a rotary mixer 26, and then aged for 5 to 10 days, and then sent to a commercialization process.

At this time, if there is concern of pest contamination, disinfect by fumigating with pesticides such as chloropicrin when overturning during deposition.

3. Commercialization Process

The top soil aged in the aging process is transferred to the hopper 28 by shovel 27, and then sent to the foreign matter sorter 29 to sort the foreign matter, and then sent to the top soil storage conveyor 31 to the storage facility of the top soil product 31. Packed and shipped.
