Activated Sludge Systems

In this study two bench scale activated sludge systems were used, a CSTR and an SBR for the treatment of coke – oven wastewater. Both reactors were inoculated with activated sludge from a municipal wastewater treatment plant. At the first stages of operation, reactors were feed by a mixture of municipal wastewater and synthetic wastewater. Full acclimatization of the microorganisms to synthetic wastewater was achieved in 60 days. The operation of the reactors was divided into three distinct periods. The first period was characterized by the treatment of high organic but non-toxic synthetic wastewater. During this period COD and BOD5 removal efficiencies reached 95 and 98% respectively, in both reactors. Nutrient removal was better in the SBR reactor rather than in the CSTR. In the second period phenol was added in concentrations up to 300 mg l-1. Degradation of phenol started about the 20th day after its introduction to the reactors. In this period no effects of phenol to nutrient removal were observed, whereas the removal efficiency of organic matter in both reactors was slightly decreased. During the third period phenol concentrations of the influent were gradually increased to 1000 mg l-1, while cyanide and thiocyanite were added to the influent composition to concentrations reaching concentrations of 20 and 250 mg l-1 respectively. The composition of the influent of this period was a full assimilation of coke oven wastewater. Introduction of increased phenol concentrations along with cyanide compounds initiated irreversible effects on the activated sludge microfauna of the CSTR causing inherent problems to the treatment process, while SBR showed greater capacity to withstand and degrade toxic compounds. The beginning of this period was characterized by decreased settleability of the suspended solids as well as decrease of organic matter and nutrient removal efficiencies. Monitoring of the effluent characteristics during this period reported over 90% for organic load, 85% of nutrient removal and over 90% of phenol and cyanide removal in SBR, while the removal efficiencies for the CSTR were 75, 65 and 80% respectively.

The main objective of the article is to develop the concept of flock fragmentation and the averaging method for the application of electrocoagulation in the process of treating wastewater from coke ovens. The designed solution was part of an innovative system for the coke oven wastewater treatment process. The system is dedicated to removing the hazardous elements and compounds from wastewater from leaching ashes in municipal waste incineration plants. The design of the process and its automatization was based on a quantitative simulation method. The balance equations of mass, energy, and momentum of transport, complemented by the kinetics of the related reaction, are used during the calculation of the process. The main result achieved is a practical solution—the reactor’s scheme, classified due to a patent procedure in the Polish Patent Office.

Industrial wastewaters with high ammonia concentrations, high toxicity and/or unfavourable COD/N ratio call for special attention and concern with regard to design and operation of the wastewater treatment system. Two cases are described: wastewater from a rendering plant and from a coke oven plant. The precondition for obtaining and maintaining a nitrification process in both a rendering plant and a coke oven plant is close control and regulation of pH in the process tanks. Both high and low values of pH cause inhibition of the nitrifiers. pH should be kept in the range 6.5-7.0. The organic fraction at the rendering plant mainly consists of easily biodegradable organic acids. The BIO-DENITRO concept has been chosen for this application and proven to be very efficient to obtain low effluent values for (NH3 + NH4)-N due to the flexibility in adjusting the phase length under variation in loadings and wastewater composition. Complete denitrification could be obtained with COD/N ratio larger than 5. Wastewater from a coke oven plant contains compounds that are extremely toxic to the nitrifiers as for example phenol, cyanide, thiocyanate, sulphide and ammonia. Sufficient upstream buffering is essential to prevent shock loads. In order to obtain complete denitrification at the coke oven plant by using an internal carbon source, it is necessary to have an efficient ammonia stripping and phenol must not be removed from wastewater. COD/N ratio must be larger than 8 to obtain complete denitrification.
