TH13122A - Processes and equipment for biological fluent purification. - Google Patents

Abstract

The process for biological purification of fluent Which makes it possible to be convinced that therapy It can be completely removed to pollutants from carbon and nitrogen at the actual output, or to separate biological substances requiring oxygen, or BOD, during a significant increase in the transmission stream. Out that is such true Especially in the presence of rainfall by the use of bacteria in the immobilized culture media by It has a special feature that it combines with the use of conditioning. Of the surrounding situation, that is, the potential of oxidation-reduction Which depends on the presence or absence of dissolved oxygen And the composition of the water in contact with the bacteria Whether it is to adjust the plant enzyme system contained in the film Bacteria of the stationary culture media to determine the Separation of biological substances at Biological oxygen demand (BOD) in the stationary culture media Which will increase to the maximum and do well Trifification or for stimulating the development of suitable plants For its intended purpose, BOD separation or nitrification is done in the same bacterial film.

Claims (2)

1. Process for biological wastewater treatment That consists of steps of The wastewater is connected in series with the normal biological filter. To form a sequence of anoxianosane denitrification Cultivated that is frozen in place Oxia and denitripike anoxia type Which will separate pollution from carbon and Nitrogen out of the wastewater Each biological filter has Immobilized cultures in which there are retotrophic and heterotrophic plants, measurement of sequential increase of wastewater flow. Later, the parallel flow of wastewater is directed to the biological filter. Instead of a series, when the incremental flow is rated, the denitrification biofilter is brought to the source of Air to combine the oxygen in the air with the carbon in the wastewater to make the heterotropic plants in the bio-purifier, and consequently reduce the biochemical oxygen demand. The return measure is the return of the normal flow rate of the wastewater. Later, the wastewater is taken to a biological filter connected in series again. Once when the normal flow rate was measured Stop feeding the air to the denitrification biofilter and rinse the tyrophilic purifier to separate the heterotrophic plants. Make it return to the level of the plant autotrophic At the beginning Therefore, it will return to the tyroscopic sequence. 2. The process specified in claim 1, in conjunction with the Pre-treatment which consists of Separation of fruit and oil from wastewater Mechanical cleaning of wastewater and regulated addition of the cleaning agent during the cycle. Changing the state of wastewater
