Problems solved by technology

While increasing the use or use of disinfectants, ultraviolet or ozone disinfection, and sterilization can inhibit the growth of viruses and bacteria, but also increase the disinfection by-products, which is extremely unfavorable to the growth of plants.
The investment and operating costs of some reverse osmosis and deep filtration technologies are too high, far beyond the tolerance of the government and ordinary residents, and the waste of water resources is huge
[0005] The active water for soilless cultivation in the prior art generally has the following problems: 1. The heavy metals in the water exceed the standard; 2. During the process of supplying plant nutrients, water and nutrient solution are easy to breed pathogenic bacteria, which brings destructive risks to crops, and Corresponding disinfection equipment is required in a closed system, which will increase investment costs; 3. The low dissolved oxygen content in water can easily cause the root system of plants to rot and hinder the growth of plants

Embodiment 1

[0029] Example 1: Prepare raw water with high concentration of heavy metal ions, let the water flow through the gradient magnetic field activation module, under the action of high-strength magnetic field, the raw water molecules clusters are untied, so that the clustered water forms a single water molecule state and is arranged in a regular manner. The effluent of the gradient magnetic field module enters the filter material layer, and the filter material layer is composed of kaolinite and montmorillonite at a weight percentage of 2:1. The filter material layer adsorbs heavy metals, and the water is purified. Various related indicators and comparisons are shown in Table 1.

Embodiment 2

[0032] Example 2: Prepare raw water with high concentration of heavy metal ions, make the water flow through the gradient magnetic field activation module, and under the action of high-intensity magnetic field, the raw water molecule clusters are untied, so that the clustered water forms a single water molecule state and is arranged in a regular manner. The effluent of the gradient magnetic field module enters the filter material layer, and the filter material layer is composed of illite and montmorillonite at a weight percentage of 3:1. The filter material layer adsorbs heavy metals, and the water is purified. Various related indicators and comparisons are shown in Table 2.

Abstract

The invention discloses a method of preparing soilless culture active water. Due to the action of a high-intensity magnetic field on the water entering from a water inlet pipe, a gradient composite disturbed magnetic field disconnects the molecular clusters of raw water so that the cluster water become water in a state with single water molecule state; under direct action of the magnetic field, 50-80% of the microorganisms die; the yielding water enters a natural ore adsorption module; a mechanism of the natural ore adsorbing heavy metals is mainly implemented in two ways: ion exchange adsorption and complexing adsorption. A synergistic effect between the gradient magnetic field and the natural ore adsorption greatly improves the effect of the ore adsorbing the heavy metals. Very few copper and silver ions are dissolved by a copper-silver metal net; in the mineralized water subjected to mineralization, the content of negative oxygen ions and dissolved oxygen is relatively high; after saturation magnetization of the water, when the applied magnetic field is removed, the magnetization effect does not disappear immediately but lasts for some a period of time; therefore, in the water after secondary magnetization, the oxygen solubility is improved.

Description

technical field [0001] The invention relates to a preparation process of active water (nutrient solution) for soilless cultivation. In particular, it relates to a process for preparing active water (nutrient solution) for soilless cultivation by using gradient magnetic field and natural ore to absorb and compound. Background technique [0002] Soilless cultivation is a new crop cultivation technology developed in recent years. The crops are not cultivated in the soil, but the crop seedlings are planted in an aqueous solution (nutrient solution) with dissolved minerals, or in some kind of cultivation substrate, the crops are cultivated with the nutrient solution. As long as there are certain cultivation equipment and certain management measures, crops can grow normally and obtain high yields. Because the cultivated crops do not use natural soil, but the cultivation of crops with nutrient solution irrigation is called soilless cultivation, also known as hydroponics or hydrop...
