Abstract
The invention discloses a system for treating refined cotton black liquor by using residual alkali and residual heat, which belongs to the field of high-concentration organic wastewater treatment equipment. It includes a regulating pool, a partition reaction pool, a three-way solenoid valve, and a dropper; the regulating pool is connected to one side of the partition reaction pool through pipeline A, and the other side of the partition reaction pool is connected through a pipeline equipped with a COD sensor Three-way solenoid valve, the three-way solenoid valve is also connected to the outlet pipeline and pipeline B respectively, and pipeline B is connected to pipeline A. The temperature sensor A and pH sensor A are installed in the regulating tank with the inlet pipeline, and the diaphragm reaction tank is equipped with There are temperature sensor B and pH sensor B, and a dropper is arranged above the partition plate reaction tank. The invention is more conducive to decomposing the macromolecular refractory organic matter in the refined cotton black liquor, and realizes the efficient removal of organic pollutants. Meanwhile, the system has simple technical process and low cost.
Description
technical field [0001] The invention relates to the field of high-concentration organic wastewater treatment equipment, in particular to a system for treating refined cotton black liquor by using residual alkali and residual heat. Background technique [0002] Refined cotton (cotton pulp) is a high-purity cellulose product made of cotton linters as raw material and refined by high-temperature cooking with alkali. It is usually used to manufacture cellulose esters, nitrocellulose (nitrocellulose) and cellulose acetate. It is widely used in food, medicine, daily chemicals, plastics, electronics, papermaking, metallurgy, aerospace and many other fields. It is known as "special industrial monosodium glutamate" and has a good market prospect; my country is the country that produces and uses refined cotton In a big country, according to statistics, the total demand for refined cotton by domestic and foreign enterprises is about 300,000 tons, the total demand for refined cotton by fo...
