Abstract

The invention discloses an integrated recombiner comprising a dosing device and a mixing filter tank. The dosing device is arranged above the mixing filter tank. The dosing device comprises dosing pipes and an overflow tank. Three dosing pipes are provided, and the top end of each dosing pipe is connected to an overflow gate. The other end of each overflow gate leads to the interior of the overflow tank. The lower end of each dosing pipe is connected to a connecting pipe, and a liquid inlet pipe and a valve are arranged on each connecting pipe with the valve located below the liquid inlet pipe. The lower end of each connecting pipe is connected to a mixing liquid inlet pipe by means of a tee fitting, and a lower end of the mixing liquid inlet pipe is connected to the top end of the mixing filter tank. A glass sand core is arranged in the middle of the mixing filtering tank, and a filtrate discharge outlet is arranged in the bottom of the same. According to the integrated recombiner, dosing, mixing and filtering are integrated, and the structure is more compact and stable; a reagent and a water sample are fed together and come into sufficient contact with each other, thereby increasing the extent of the chemical reaction and improving the measurement sensitivity.

Description

technical field [0001] The invention relates to a water quality monitoring instrument, in particular to an integrated composite device. Background technique [0002] Chemical oxygen demand (abbreviated as COD) is a comprehensive indicator of water quality organic pollution, and is one of the most important items in water quality routine monitoring. my country's national standard (GB 17378.4-2007) stipulates that potassium permanganate is used as an oxidant to oxidize seawater samples under alkaline conditions, and the chemical oxygen demand is calculated by the consumption of oxidant potassium permanganate. [0003] Standard methods are complex, time-consuming, and laborious to operate. Therefore, exploring simple, fast and automatic COD analysis methods and instruments has always been the goal of environmental monitoring workers. Since the 1980s, the Japanese scholar Iyong Takashi first introduced the flow injection analysis technology into the COD online measurement, and...
