Problems solved by technology

[0002] With the rapid development of industrial and agricultural production, the water quality of water sources is becoming more and more serious, and the types of pollutants tend to be complicated and diversified. The persistent organic pollutants, biodegradable organic substances, and mutagenic substances in the water body make the conventional water treatment process no longer available. In order to effectively remove toxic and harmful organic pollutants in water, biological treatment technology has been widely

[0027] Specific implementation mode 2 The carrier immobilization condition of composite bacterial agent of the present invention:

[0028] Using activated carbon as a carrier, the composite bacterial agent obtained in the present invention is used in the drinking water biological activated carbon filter, and the immobilization method: adopts the physical circulation adsorption method to mix the composite bacterial agent with the filter water, and utilizes gravity to make the mixed bacterial agent The compound bacterial agent passes through the filter tank from top to bottom, and the fixing conditions are:

[0029] 1. Fixed flow rate: The fixed filtration rate is to ensure that the composite bacterial agent has a certain residence time after contacting the surface of the carrier to complete the growth process of the composite bacterial agent on the carrier surface. The fixed flow rate is determined to be 2L / h.

[0030] 2. Fixed time: The fixed time is the time when the com...

Abstract

The invention relates to a preparation method for a compound fungus agent for specifically degrading an organic matter for a biological enhancing water treatment system. The compound fungus agent is added into a biological treatment process, has high biological activity, a stable effect and low cost, is easy to adsorb on the surface of a carrier and is difficult to lose. The preparation method issimple and practical, and has a short preparation period and low cost. The compound fungus agent comprises the following four strains: 20 to 30 percent of pseudomonas-stutzeri, 20 to 30 percent of pseudomonas putida, 10 to 20 percent of pseudomonas-pertucinogena and 30 to 50 percent of bacillus subtilis. The compound fungus agent is prepared by combining and screening the strains, performing slant culture and primary culture, mixing according to the proportion, and performing secondary cycle culture. The preparation method is widely used in a biological enhancing water treatment process, has a long-term and stable operation period, and has specific degradation ability for toxic and harmful organic pollutants such as halogenated hydrocarbons, phenol, benzoic acid, aromatics, polycyclic aromatic hydrocarbon, heterocyclic compounds, phthalic acid ester and the like.

Description

technical field [0001] The invention relates to a preparation and application method of a specific organic matter degrading composite bacterial agent used in a biologically enhanced water treatment system, in particular to a preparation and application method composed of Pseudomonas stutzeri, Pseudomonas putida, Pseudomonas perforatum and Bacillus subtilis Preparation and application method of composite bacterial agent composed of bacillus. Background technique [0002] With the rapid development of industrial and agricultural production, the water quality of water sources is becoming more and more serious, and the types of pollutants tend to be complicated and diversified. The presence of persistent organic pollutants, biodegradable organic substances, and mutagenic substances in water bodies has made conventional water treatment processes no longer available. It seems powerless. In order to effectively remove toxic and harmful organic pollutants in water, biological treatm...
