Removal of High-Strength of Ammonium and Phenol from Coking Wastewater by Alcaligenes Faecalis No.4
Alcaligenes faecalis No.4, which is capable of heterotrophic nitrification and aerobic denitrification was used to treat coking wastewater (CW) to remove high-strength of ammonium and phenol. First, the phenol-degrading ability of No.4 was verified and a synthetic medium containing lactate and phenol as carbon sources was subsequently applied to the No.4 culture. Both carbon materials were enti...
متن کاملHeterotrophic Nitrification and AerobicDenitrification of a Wastewater from a ChemicalCompany by Alcaligenes faecalis No.4
A wastewater from a chemical company (abbreviated as WC) containing approximately 5000 mg NH4-N/L ammonium and a slight amount of BOD was treated with Alcaligenes faecalis No.4 (No.4),which is capable of heterotrophic nitrification and aerobic denitrification. The repeatedbatch operation was conducted at 30°C for 900 h at controlled dissolved oxygen concentration (DO) of 2-3 mg/L in the presenc...
متن کاملEfficacy of Microalgae on the Removal of Pollutants from Wastewater
Expansion of urban populations, increased coverage of domestic water supply and sewerage give rise to greater quantities of municipal wastewater. With the current emphasis on environmental health and water pollution issues, there is an increasing discharge of waste water in developing countries. Present technologies in developing countries for treating waste water are not sufficient and cost ef...
متن کاملChromium bioremediation by Alcaligenes sp. strain newly isolated from chromite mine of Sabzevar
In this work, CKCr-6A strain was found to be highly resistant to some toxic heavy metals such as Cr+6, Cr+3, Cu+2, Co+2, Cd+2, Pb+2, Hg+2, U+6, tellurium, and selenite. Herein, high chromate tolerance of an isolated strain is reported with a high minimum inhibitory concentration value of 80,000 mg/L and the ...
