Traditional chemical-machinery producing mainly took the refiner as the primary refining equipment. Extrusion pulping was the reformation of traditional refining pulping. The different equipments and processes resulted in the different characteristics of wastewater inevitably. This article aimed to compare the characteristics and biochemical treatment methods between conventional chemical-mechanical pulping and extrusion pulping, and then discuss the biochemical treatment advantages of extrusion pulping wastewater. The result shows that: the wastewater from the extrusion pulping has lower concentration of tiny fiber, load suspended matter, wastewater temperature and effluent discharge. And thus make a simpler process, a lower cost and a better effect of the wastewater treatment.

Global Population

Increasing global population intensifies the food demand pressure while meeting the increasing environmental legislation. To cater for such demand, agriculture sector shifts for mass food production accompanied with the use of a large amount of agrochemicals such as fertilizers, pesticides, antibiotics, and growth hormones. As a result, these agrochemicals' residues pollute the ecosystem and environment through surface runoff. It has been a great challenge in treating agricultural runoff due to its contaminant loadings and wide variability of different compounds in the wastewater to meet the stringent standards in an economically feasible manner. This chapter delineates the current state-of-the-art of wastewater treatment methods for agricultural runoff.

Final Effluent

Waste stabilisation ponds (WSP) have been a popular form of wastewater treatment in New Zealand both for large cities and small communities. Most WSP were constructed from 1960 to 1985 and were single ponds or a primary and secondary pond in series of similar size. Since 1995, improvements comprising primary and maturation ponds, with four to six cells in series have been constructed or retrofitted to original two cell ponds. The Seddon and Blenheim ponds include in-bank rock filters between maturation cells as a lower cost way of providing this feature for reduction of solids. Operating results show reduced variability in final effluent quality for BOD and SS. In addition, very good reductions of faecal coliform and enterococci have been achieved along with good reductions of ammonia and total nitrogen for most of the year except the middle of winter. Extensive use of rock as rip-rap bank protection and in the rock filters, appears to have provided sufficient extra surface area for a nitrifying biofilm to develop.

Different Characteristics

The identification of adequate wastewater treatment for small communities is a complex problem since it demands a combination of data from different sources, such as aspects of the community and landscape, the receiving environment and the available wastewater treatment technologies. The Catalan Water Agency (Agència Catalana de l'Aigua) considered using an EDSS (Environmental Decision Support System) as a tool to help water managers select the most adequate treatment for the urban wastewater of nearly 3,500 small communities in Catalonia (Spain). From that moment, EDSS was applied to all the river basins in Catalonia. In this paper the authors present the results obtained for the 76 small communities located in one of these river basins: the Fluvia River Basin. The characteristics of the community used in the reasoning process of the EDSS, the list of selected wastewater treatment alternatives, the technical environmental justification for the selected treatments and the reasons for discarding, favouring or disadvantaging them are presented. Finally, some results for the Fluvia River Basin are compared with those obtained in other Catalan river basins with different characteristics in order to evaluate which are the significant features in identifying adequate wastewater treatments.

The Impact

Several aspects of using ashes from sewage sludge incineration in the brick and tile industry have been examined. After discussing the item of ash production in Germany, the impact of different wastewater treatment methods is described; for instance, the use of precipitation agents containing iron will considerably influence the ash quality. Depending on their respective chemical composition, different ashes have different effects on the ceramic qualities of the bricks made of clay blended with ashes. These effects will be shown in regard to the major ceramic parameters. Similarly, the quality of the ashes also influences the elution behaviour and the mineral fixation of heavy metals.
