Problems solved by technology

In the process of soil heavy metal pollution, especially farmland pollution, since the pollutants come from nearby exhaust gas and irrigation water, the free heavy metal ions are easy to diffuse after entering the farmland, making it more difficult to repair

Embodiment Construction

[0029] Below, the present invention will be described in detail with reference to the accompanying drawings.

[0030] Such as figure 1 As shown, the soil remediation system 10 is set up next to the pool 11 . The water in the pool 11 enters into a movable system 15 through the filtering equipment 12 and the water pump 14 . The mobile system 15 includes: an electrolysis device 16 , a gas-liquid mixing device 18 , a pressure adjustment tank 22 and an electric control box 28 . Among them, the gas-liquid mixing device 18 is provided with a gas one-way valve 20 for inputting gas, the pressure regulating tank 22 is provided with a solenoid valve 24 for releasing excess gas, and the electrolysis device 16 is provided with a positive electrode 16A and a negative electrode 16B.

[0031] When the water passes through the electrolysis device 16, an immediate electrolysis reaction is generated to produce small molecule water and electrolytic ions. The water generates hydrogen ions at th...

Abstract

The invention provides a soil remediation method and system as well as a method for solidifying heavy metal in soil. The soil remediation system comprises electrolysis equipment, a gas-liquid mixing device, an electric control box and a pressure regulating tank. According to the soil remediation method and system disclosed by the invention, micro-nano bubbly water containing electrolysis ions is generated, and micro-nano bubbly water containing electrolysis ions is input into soil, so that the electrolysis ions are combined with heavy metal ions in soil to form solids which cannot be absorbedby roots of crops, and therefore, content of heavy metal in soil is reduced. Meanwhile, micro-nano bubbles are cracked to release oxygen gas into soil, so that content of oxygen gas in soil is increased, a soil hardening phenomenon is eliminated, and the purpose of remediating soil is finally achieved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a soil remediation method and system and a method for solidifying heavy metals in soil. Background technique [0002] Protecting the soil environment is an important part of maintaining ecological balance and promoting ecological construction, and is related to the sustainable development of social economy. But in the past, due to the extensive development of industries, the soil environment in many areas was worrying, and some areas were seriously polluted. [0003] Soil pollution can be divided into heavy metal pollution and petrochemical pollution. Non-ferrous metal smelting, petroleum processing, chemical industry, coking, electroplating, tanning, bleaching and dyeing, circuit boards, metal surface treatment, pharmaceutical manufacturing, lead-acid batteries, waste electronic dismantling, hazardous waste treatment, etc. will all produce soil pollution. Exhaust gas ...
