Abstract

The invention relates to a system and a method for recovering picloram in wastewater. The system comprises a wastewater storage device, a leacheate storage device, an acid liquor storage device, an adsorption device, a wastewater collection device, a picloram salt collection device, a picloram collection device and a separation device, wherein the adsorption device is respectively connected with the wastewater storage device, the leacheate storage device, the wastewater collection device and the picloram collection device; the acid liquor storage device and the picloram salt collection device are both connected with the picloram collection device; and the picloram collection device is connected with the separation device. According to the system, on one hand, wastewater can be purified, the COD of the wastewater is reduced to 130-180 mg / L, and the chromaticity is reduced to 25-30 times; on the other hand, 5-10 kg of picloram can be recovered from each ton of wastewater through the desorption and adsorption device, and the recovery effect is good.

Description

technical field [0001] The invention belongs to the field of waste water recovery, and in particular relates to a system and a recovery method for recovering amiloride in waste water. Background technique [0002] Amiloride is an organic chemical substance with the molecular formula C 6 h 3 Cl 3 N 2 o 2 , also known as picloram. Amclopyral is mainly used to control broad-leaved weeds and shrubs in forests, wasteland and other non-cultivated lands, with an effective dosage of 100-200 grams per mu. [0003] At present, a small amount of amiloride is dissolved in the wastewater of amiloride. Due to the stability of the pyridine ring, the wastewater is difficult to be treated by the existing technology, and the recovery effect is not good. [0004] Therefore based on this, propose technical scheme of the present invention. Contents of the invention [0005] In order to solve the problems existing in the prior art, the present invention provides a system and a recovery m...
