Abstract

The invention discloses a screening and domesticating method of microbial flora used for purifying water quality of gardens. The screening and domesticating method comprises the following steps: obtaining a bacterium source sample from sludge of water ponds of the gardens; preparing an enrichment culture medium according to nutritional requirements of efficient purification flora; adding the bacterium source sample into the enrichment culture medium and carrying out rapid enrichment culture to obtain a culture solution, so as to rapidly enrich a lot of flora, with high pertinence and high enrichment efficiency; utilizing a designed domesticating device and adding nutrient substances; carrying out domesticating treatment to obtain the microbial flora. The domesticating device has the advantages of simple structure, energy saving and high efficiency and high practicability; under a normal-temperature condition, the screened microbial flora can be domesticated through natural pressure difference, natural water temperatures and the like and a domesticating process is energy-saving and environmentally friendly; the method disclosed by the invention is economical, efficient, energy-saving and practical; after the screened microbial flora are domesticated, the microbial flora can be rapidly adapted to a water environment of the gardens; the efficient purification of sewage pond water of the water ponds of the gardens can be realized; the screening and domesticating method is ecologically safe, has no pollution and a high adaptive capacity, and is convenient for large-area application and popularization.

Description

technical field [0001] The invention belongs to the technical field of biological environment treatment, and in particular relates to a method for screening and domesticating microbial flora used for garden water purification. Background technique [0002] In recent years, with the continuous improvement of living standards, people are paying more and more attention to the natural environment of houses while improving their living conditions. Therefore, a large number of real estate projects have added landscaping and landscape water design to enhance the scenery of the community. However, at present, the waterscapes of many projects are located on the top of underground garages. Reinforced concrete structures are adopted to prevent water leakage. Most of the water bodies are closed and slow-flowing water bodies with static or poor fluidity. The self-purification ability is basically lost, so the ecological balance of the water body is very easy to be unbalanced. Especially...
