摘要

Small scale industrial unit for treatment and injection of chemical oxidizing and reducing for in situ remediation of soil and groundwater.This utility model, belonging to the field of devices to make harmless or keep away from harmful chemicals, refers to an industrial unit mobile small scale injection of chemical compounds, oxidants and / or reducers, aiming to the remediation of soils and insitu Subterru00e1neas waters.The industrial unit consists of two injection systems in parallel mounted on a mobile structure, and a system for preparation and injection of nanoparticles and other system for preparation and injection of chemical oxidants.Both systems are automated, allowing the control transfer pump and injection, as well as the control rates of injection (flow rate) and pressure applied. The injection of the solutions is carried out by means of injection wells through the connection of the probes injection and continued monitoring.The industrial unit, as shown in the figures up to h consists of a unit of small size, which is divided into two large groups of equipment as to the possibility of injection techniques: a) preparation and injection of the oxidizing solutions: part of the unit is composed of reserv Report of water injection and lung oxidant,Tanks for the preparation and mixed solutions and electrical system for actuation of a pump system and, finally, support for transfer hoses of the solutions of the buffer tank at the point of injection.The unit allows the injection of the solutions of interest at different points in the area of interest; (b) preparation and injection of a suspension of nanoparticles of metals or alloys bimetallic: part of the unit consisting of two containers (11) with agitation system (111) for the preparation of the Susp Ensu00e3o, buffer tank (221) and the injection pump system (113).For this type of solution, the unit allows the injection at different points in the area of interest; and the probe injection and monitoring, acting as a closure of the well head, which allows the monitoring of continuous injection process, ensuring a greater control and security during The applications of the techniques of remediation.The industrial unit can also be used for the application of bioremediation, i.e., for biological treatment of contaminants, and the solution with a certain concentration of biological material can be prepared in a module of treatment and then added via probes Wai Cificas,The module of treatment can be used for aeration of the soil via the addition of oxygen or nitrogen peroxide, to provide an environment for performance of aerobic microorganisms in the remediation of soil remediation. In addition, this module can also be used in the agricul The fracture, such as, for example, in the injection of fertilizers and other components to enrich the soil for agricultural activity.
