Abstract
The invention discloses a system for treating refined black cotton wastewater by residual alkali and residual heat, and belongs to the field of high-concentration organic wastewater treatment equipment. The system includes a regulating tank, a separating plate reaction tank, a three-way solenoid valve and drop feeders. The regulating tank is connected to one side of the separating plate reaction tank through a pipeline A. The other side of the separating plate reaction tank is connected to the three-way solenoid valve through a pipeline provided with a COD sensor. The three-way solenoid valve is also connected to an outlet pipeline and a pipeline B. The pipeline B communicates with the pipeline A. The regulating tank provided with an inlet pipeline is provided with a temperature sensor A and a pH sensor A. A temperature sensor B and a pH sensor B are arranged in the separating plate reaction tank. The drop feeders are arranged above the separating plate reaction tank. The system of the invention is more advantageous for removing macromolecule refractory organic matters in the refined black cotton wastewater to effectively remove organic pollutants. Meanwhile, the system has the advantages of 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...
