Abstract

The invention discloses a bioreactor for soil restoration. The bioreactor for soil restoration comprises a tank body, wherein the top of the tank body is provided with a matching cover body; a jacketis welded out of the tank body; a plurality of liquid-adding adapters are arranged on the cover body, and the liquid-adding adapters penetrate the cover body and extend into the tank body; the cover body is further provided with a feeding port, a feed-supplementing port, a spare port and an exhaust port; a feed-supplementing pin is inserted into the feed-supplementing port; an air inlet is formedin one side of the tank body; a through hole is formed in one side of the body; a side-view mirror is sealed in the through hole; a discharge outlet is formed in the bottom of the tank body; a stirring shaft is arranged on the cover body; the upper end of the stirring shaft is driven by a motor, and the lower end of the stirring shaft penetrates the cover body and extends to the lower part of thetank body; a cylindrical microporous screen sleeves the stirring shaft; the inner side of the cover body is provided with an LED illumination lamp with adjustable light intensity and a lamp view mirror; and the side wall of the tank body is provided with an overflow port, a temperature sensor interface, a PH meter interface and a pressure gauge port. The bioreactor for soil restoration is simple in structure, convenient to use and good in restoration effect.

Description

Technical field: [0001] The invention relates to a bioreactor, in particular to a bioreactor for soil restoration. Background technique: [0002] Extensive industrial and agricultural activities of human beings often lead to soil pollution. Common soil pollution includes heavy metal pollution and organic pollution. In recent years, countries have begun to attach importance to the control of soil pollution, and its technology has developed very rapidly. Among them, bioremediation technology is considered to have the most vitality. At present, the soil bioremediation technology adopted includes in-situ treatment, on-site treatment and bioreactor. The bioreactor can give full play to the advantages of biological methods and is the most effective treatment process in the bioremediation technology of contaminated soil. Bioreactors are usually horizontal, rotary drum, and air stripping, and can be built on the polluted site or treated off-site. The existing bioreactors for soil...
