Embodiment 1

[0046] A method for extracting landfill seepage to prepare liquid water, comprising the steps of:

[0047] A. Carry out detoxification and harmless treatment of landfill leachate;

[0048] B. Use drip irrigation technology to regularly and quantitatively transport the treated landfill leachate to the roots of coconut trees to solve the water and nutrients needed for plant growth;

[0049] C. Extract water from the fruit leaves of the coconut tree for use.

[0050] In the step A and the step B, the detoxification treatment, harmless treatment and drip irrigation all adopt automatic control.

[0051] In the step A, the detoxification treatment adopts UV-vis / iron oxalate complex / H 2 o 2 Oxidation treatment is carried out by the method, the treatment pH is 3, and the treatment is 1h under ultraviolet light, the wavelength of ultraviolet light is 254nm, and the power is 20W; the treatment liquid includes: H with a mass fraction of 30% 2 o 2 1.3 mL, H 2 o 2 / FeSO 4 ·7H 2 T...

Abstract

The invention relates to the technical field of garbage leachate and particularly relates to a method for preparing liquid water by extracting garbage leachate. The method comprises the following steps of a, carrying out detoxification treatment and innocent treatment on garbage leachate; b, regularly and quantitatively conveying treated garbage leachate to the roots of coconut trees by using a drip irrigation technology to meet the requirements for water and nutrition in the plant growth process; and c, extracting water from fruits and leaves of the coconut trees to be used. According to the method disclosed by the invention, the treated garbage leachate is conveyed to the roots of the coconut trees, and then, the water is extracted from the fruits and leaves of the coconut trees so as to be used, so that the method is simple and convenient to operate; in addition, the garbage leachate can be recycled, so that the problem of fresh water insufficiency in a seaside garbage dump can be solved, the cost can be reduced, and the ecological environmental protection effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of landfill leachate, in particular to a method for extracting landfill leachate to prepare liquid water. Background technique [0002] Municipal landfill leachate is a kind of sewage with complex components. Because of its high concentration of organic matter, high content of ammonia nitrogen, large amount of heavy metals, and large changes in water quality over time, it has been valued by countries all over the world, and a lot of research has been done on its treatment. Research. At present, the most widely used method for treating landfill leachate is biochemical method, but most of the existing treated landfill leachate is directly discharged, and there is no other application. Especially at the seaside, there is a serious shortage of fresh water resources. If the landfill leachate can be recycled to produce liquid pure water, it will generate huge economic and social benefits. Contents of the invent...
