Functional bacterial flora establishment method applicable to black and odorous water body treatment and method for treating black and odorous water body with bacterial flora

Abstract

The invention provides a functional bacterial flora establishment method applicable to black and odorous water body treatment and a method for treating black and odorous water bodies with bacterial florae. The functional bacterial flora establishment method mainly comprises the following steps: (1) sampling indigenous microorganisms; (2) establishing functional bacterial florae in a black and odorous water environment, namely preparing a nutrient liquid, inoculating, and carrying out primary culture and secondary culture. The method for treating black and odorous water bodies with the bacterial florae mainly comprises the following steps: (1) carrying out feeding and operation; (2) replenishing the functional bacterial florae at regular time, and culturing continuously. By adopting the method, a set of complete functional bacterial flora 'continuous culture-regular replenishing' integral procedures are established on a black and odorous water body treatment site, and ammonia nitrogen removal effects on treated water bodies are continuously intensified. The method has wide applicability to various black and odorous river channels, black and odorous lakes, polluted field black and odorous ground surface, and the like, the functional bacterial florae are established in an original water quality environment, the bacterial florae constitution is dynamically changed, and the method is good in applicability, remarkable in effect and particularly applicable to implementation on various black and odorous water body treatment sites.

Description

technical field [0001] The invention belongs to the technical field of biochemistry and environmental protection, and provides a method for constructing functional flora suitable for the treatment of black and odorous water bodies and a method for applying the flora to treat black and odorous water bodies. The method can realize the use of indigenous microorganisms and Inoculate sludge to establish a complete set of integrated process of "continuous culture-regular dosing" of functional bacteria, and continuously strengthen the ammonia nitrogen removal effect of the treated water. Background technique [0002] With the rapid development of my country's urban economy, the scale of cities is expanding day by day, urban environmental infrastructure is increasingly insufficient, urban sewage discharge is increasing, a large number of pollutants enter rivers and lakes, and the concentration of COD, nitrogen, phosphorus and other pollutants in water exceeds the standard.

Problems solved by technology

[0005] However, the above-mentioned technologies and products have certain limitations. It is difficult to guarantee the environmental adaptability of a single strain, and it is difficult to grow dominantly or degrade ammonia nitrogen efficiently. In the smelly water environment, the product is not specific to specific water bodies, and it is difficult to guarantee the adaptability to the treatment of black and smelly water bodies. Causes overlapping with the niche of indigenous bacteria in black and odorous water bodies, causing adverse effects on the system

At the same time, because nitrifying bacteria are sensitive to environmental changes and are vulnerable to impacts in black and odorous water environments, they need to be continuously added in large quantities in many cases. Most of the commercially available bacterial agents are expensive and costly to use

Judging from the existing research results, at the treatment site of black and odorous water bodies, a complete set of integrated process of "continuous culture-regular dosing" of functional flora is established by using indigenous microorganisms and inoculated sludge to continuously strengthen the treated water bodies The technical methods and engineering examples of ammonia nitrogen removal effect are still rare
