Abstract

The invention discloses a multifunctional microbial agent delivery device for in-situ remediation of organically polluted soil. The device comprises a plowing system, a microbial agent supply system and a spraying system, wherein the plowing system comprises a first mounting seat, a spiral plowing structure and a driving structure, the spiral soil turning structure is rotationally connected with the first mounting seat, the driving structure is used for driving the spiral soil turning structure to rotate, the spraying system comprises a spray head and a pressure pump, and the pressure pump isconnected between the microbial agent supply system and the spray head through pipelines. The device improves the contact efficiency of soil pollution sources and degrading bacteria by adopting a modeof simultaneous soil turning and bacteria addition, creates a good ventilation environment so as to be suitable for the growth of degrading bacteria, achieves the double effects of soil loosening anddegradation, and solves the problems of low degrading bacteria throwing efficiency, uneven bacteria throwing and low degrading efficiency.

Description

technical field [0001] The invention relates to the technical field of in-situ remediation of pesticide soil, in particular to a multifunctional biological agent delivery device for in-situ remediation of organically polluted soil. Background technique [0002] Due to the development of modern agriculture, chemical pesticides are being used in large quantities for a long time, and the problem of excessive pesticide residues in agricultural products such as vegetables and grains is serious, which not only affects the quality of agricultural products, but also poses potential hazards to human health. Pesticide residues can enter the human body through eating, skin contact and breathing. Toxic and harmful pesticides in the soil will enter groundwater and rivers with rainwater, directly or indirectly damaging human life and health. Therefore, solving the problem of pesticide residues in soil has become a hot spot and key issue for scientific research workers. [0003] For the m...
