A treatment plant using conventional biological treatment combined with hydroponics and microalgae is constructed in a greenhouse in the area of Stockholm, Sweden. The treatment plant is built for research purposes and presently treats 0.559 m3 of domestic wastewater from the surrounding area per day. The system uses anoxic pre-denitrification followed by aerobic tanks for nitrification and plant growth. A microalgal step further reduces phosphorus, and a final sand filter polishes the water. During a three week period in July 2002 the treatment capacity of this system was evaluated with respect to removal of organic matter, phosphorus and nitrogen. 90% COD removal was obtained early in the system. Nitrification and denitrification was well established with total nitrogen reduction of 72%. Phosphorus was removed by 47% in the process. However, higher phosphorus removal values are expected as the microalgal step will be further developed. The results show that acceptable treatment can be achieved using this kind of system. Further optimisation of the system will lead to clean water as well as valuable plants to be harvested from the nutrient rich wastewater.

Рассмотрены вопросы, связанные с проведением пусконаладочных работ биоблока станции очистки хозяйственно-бытовых и близких к ним по составу сточных вод при пробном пуске в эксплуатацию очистных сооружений. Подробно рассмотрены этапы пусконаладочных работ биоблока очистных сооружений с «затравкой» активным илом из действующих биологических очистных сооружений и с дозировкой легкоокисляемой органики. Описан состав оборудования станции КОС-9 производства «Гермес Групп». Рассмотрены все этапы пусконаладочных работ биоблока на примере запуска очистных сооружений КОС-9 с привлечением многочисленных опытных данных. Определены периоды этапов пусконаладки биоблока. Приведены проблемы наладки биоблока и пути их решения с достижением требуемого результата. Технология, используемая на станции, обеспечивает очистку сточных вод, соответствующую требованиям, предъявляемым к выпуску очищенных стоков в водоем рыбохозяйственного значения. Issues related to commissioning a biological treatment plant at the facilities for household and similar in composition wastewater treatment during the trial start of the treatment facilities are considered. The stages of commissioning a biological treatment plant at the wastewater treatment facilities with «inoculating» activated sludge from the operating biological treatment facilities and with dosing easily oxidable organic matter are considered in detail. The equipment configuration of the WWTP-9 produced by Germes Group is described. All stages of the biological treatment plant commissioning are considered through the example of the start-up of WWTP-9 with the use of numerous experimental data. The periods of biological treatment plant commissioning stages have been determined. The problems of adjusting the biological treatment plant and the ways of their elimination to achieve the required result are presented. The technology used at the WWT facilities provides for the effluent quality that meets the requirements for the discharge into a water body of commercial fishing importance.

Domestic Wastewater Treatment

As population increases, domestic wastewater generated will increase as well. Domestic wastewater needs to be treated properly so as not to pollute the recipient's water body. Kampung Kandang already has a communal domestic wastewater treatment plant (WWTP) to treat domestic wastewater generated by citizens. The problem from the citizens is that the WWTP needs to be rehabilitated because the amount of sludge floating in the first biological treatment tank and still has a disturbing odor. Alternative solution for this problem is by rehabilitating WWTPs so that their functions are more optimal. The purpose of this study was to evaluate domestic wastewater in Kampung Kandang. The methods used in evaluating the wastewater i.e. analysis of primary data, calculation of standard stream evaluation and calculation of removal percentage. Communal Domestic WWTP needs to remove COD, BOD, TSS, Ammonia, and Total Coliforms parameters of 97.7%, 98.9%, 42.7%, 95.6%, and 99.9%. WWTP has already removed the TSS and ammonia. BOD, COD, and total coliform should be reduced by WWTP as much for each parameter are 25, 9%, 35%, and 95, 83%. Wastewater evaluation data can be used as a basis for the design of rehabilitation to be carried out at the Communal Domestic WWTP in Kampung Kandang.

This paper evaluates the results from a 12-month study of a single-household wastewater treatment plant with submerged membrane module (household MBR plant) that was monitored from winter to winter season. The samples were collected at least twice a week (an intensive research study at real conditions). The household MBR (membrane bioreactor) plant was linked to a family house with 4 residents. In this study the treatment plant was fed by real domestic wastewater. In contrast to most other experiments with small-scale WWTPs (wastewater treatment plants) carried out in laboratories and facilities of large municipal WWTPs (polygons) which guarantee stable and flexible operation but the characteristics of wastewater and activated sludge in these studies usually differ from those that occur in real small-scale/single-household WWTPs. One of the main goals of this research was to test the response of membrane and activated sludge to different conditions during real operation of the household MBR plant, such as a long period of zero influent/load, or vice versa the presence of a large amount of concentrated wastewater (e.g. during the weekend), very low winter temperatures (water temperature below 5–6°C), high pH values, and the presence of domestic detergents.

Biological Phosphorus

Hydrolysis acidification / pre-denitrification biological aerated filter was adopted in a domestic wastewater treatment plant. The effluent was accorded with a standard in the Integrated Wastewater Discharge Standard（GB18918-2002）, in which the effluent phosphorus was demanded below 0.5mg/L. Through analysis on the process biological phosphorus removal, biological method can be found to total phosphorus 1.5 mg/L. If you reach level to an emissions standards, phosphorus chemical experiment research, finally determined by strategy for the CN pool, point for adding potions FeCl3, dosing quantity for 35mg/L.
