Biological Treatment Process

The essence of the two phase anaerobic biological treatment process is to place acid bacteria and methane-producing bacteria in two reactors respectively, where it can provide the optimal conditions for their growth and metabolism, allowing them to live up to their maximal activity, which greatly improve processing capacity and efficiency compared to a single-phase anaerobic digestion. The paper start with the two phase anaerobic digestion process, in order to discuss the development direction of high efficient anaerobic digestion system.

Processing Techniques

The characteristics and the utilization situation of fruit and vegetable wastes (FVW) were analyzed, and a detailed research conducted on FVW treatment process techniques of single-phase and two-phase anaerobic digestion were summarized. Then the advantages and disadvantages between these two processing techniques are reviewed, respectively. Furthermore, future trends in research and development of FVW treatment process technology have also been briefly discussed, which would provide some new ideas for processing FVW.

Biological Treatment Process

A biological treatment process has been suggested as the main treatment stage for a high (organic) strength industrial wastewater stream, discharged by several chemical industries within a large industrial park. Treatability studies have indicated that the wastes contain a fraction of toxic and non-biodegradable organic matter, which limits the implementation of a conventional biological treatment process for the combined wastewater stream. Therefore, an in-plant control program including waste segregation and process-specific pretreatments is proposed. A protocol that enables selection of waste streams amenable to biological treatment and identification of problematic streams requiring pretreatment is presented and demonstrated. It includes simplified laboratory procedures used for chemical and toxicological characterization of source streams originating in various processes. The results can be used for the development of a pretreatment program for problematic waste streams, based upon local small-scale solutions.
