ACTIVE CARBON AND MICROORGANISM COUPLING DEVICE FOR REMOVING PESTICIDE OUT OF FARMLAND DRAINAGE WATER

摘要

An active carbon and microorganism coupling device for removing pesticide out of farmland drainage water. The structure of the device comprises: a permeable mounting tank (1), coarse grid interception nets (8), embedded filter walls (3), and fixing piles (4). The permeable mounting tank (1) is provided with clamping grooves (2) and narrow grooves (9); the bottom of the permeable mounting tank (1) and two surfaces, parallel to the length direction of a farmland drainage ditch, of the permeable mounting tank (1) are closed respectively by means of a bottom baffle plate (10) and side baffle plates (5); the permeable mounting tank (1) is fixed in the farmland drainage ditch by means of the fixing piles (4). The embedded filter walls (3) are provided in the clamping grooves (2). The coarse grid interception nets (8) are inserted into the narrow grooves (9). The device is mounted in a farmland drainage ditch, so that the device has the advantages that: no land area is occupied; pesticide removing efficiency is high; a water body is purified thoroughly layer by layer; the drainage capacity of the original ditch is not affected; updating treatment and recycling are facilitated; and the device is simple in manufacturing, low in implementation cost and easy to be maintained and managed.
