Problems solved by technology

[0004] In order to overcome the problem that microorganisms in coking wastewater treated by conventional biological treatment methods are easily inhibited or poisoned, and the treatment efficiency is not high, and to improve the toxicity resistance and treatment efficiency of coking wastewater in the biological treatment system, the present invention adds a biological treatment promoting agent to the conventional biological treatment system. Agents, including carbon sources, nitrogen sources, phosphorus sources, inorganic salts, nutrients and other primary substrates, start the co-metabolism of microorganisms, so as to treat coking wastewater stably and efficiently

Abstract

The invention discloses a coking wastewater biological treatment promoter and belongs to the field of wastewater treatment. According to the method, glucose, zinc acetate, potassium acetate, ammonium dihydrogen phosphate, magnesium chloride, ferric sulfate and vitamin B6 are smashed, mixed and made into the coking wastewater biological treatment promoter. The promoter overcomes the defects that microorganisms are inhibited or poisoned easily, and the efficiency is low when coking wastewater is treated through a common biological treatment method, the co-metabolism effect of the microorganisms is initiated, the poison tolerance and the treatment efficiency of a biological treatment system on the coking wastewater are improved, and therefore the coking wastewater can be treated stably and efficiently.

Description

technical field [0001] The invention relates to the preparation and application of a biological treatment accelerator, in particular to a coking wastewater biological treatment accelerator and its preparation method and application, belonging to the field of wastewater treatment. Background technique [0002] Coking wastewater is the wastewater of a large number of aromatic compounds and heterocyclic compounds produced in the process of coal coke, gas purification and coking product recovery. Coking wastewater is a recognized industrial wastewater that is difficult to treat. At present, coking wastewater is mainly treated by biological methods. However, when conventional biological treatment methods are used to treat coking wastewater, there are problems that microorganisms are easily inhibited or poisoned, and the effluent indicators are unstable after treatment. Therefore, how to strengthen biological treatment to improve the toxicity and treatment of coking wastewater Ef...
