Abstract

The invention provides an ecological restoration and treatment method for a black and odorous water body. The method comprises the following steps: S1, mounting a water activating machine on the watersurface of the black and odorous water body; S2, installing a waterwheel aerator on the water surface of the black and odorous water body; and S3, applying a microecological preparation to the blackand odorous water body; wherein the dosage of the microecological preparation is 350-550 g / 1000 m<3>; the microecological preparation is prepared from the following components in parts by weight: 21 to 36 parts of aerobic beneficial bacteria complex flora, 17 to 28 parts of pseudomonas complex flora, 12 to 17 parts of photosynthetic bacteria complex flora, 15 to 32 parts of gordonia complex flora,11 to 19 parts of nutrient substances, 6 to 14 parts of hydrolase and 55 to 68 parts of solid carriers. After the ecological system of the black and odorous water body is repaired by the method, thestable ecological system and the self-purification capacity of the water body can be maintained only by keeping flowing water, properly oxygenating and supplementing a small amount of gradually-aged micro-ecological preparation regularly, so that the maintenance cost is low. The method for treating the black and odorous water body is a black and odorous water body treatment technology which is lowin equipment investment, high in pollution treatment speed, low in operation cost and high in sustainability.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an ecological restoration and treatment method for black and odorous water bodies. Background technique [0002] Urban black and odorous water body refers to the general term for water bodies that present unpleasant colors and / or emit unpleasant odors in urban built-up areas. Generally, black and odorous water mainly has the following characteristics: serious organic pollution, obvious eutrophication; black or pan-black color; irritating smell; low dissolved oxygen content in water body; poor transparency and high ammonia nitrogen content. [0003] Black and odorous water is an extreme phenomenon of water pollution, in which insufficient dissolved oxygen and low self-purification ability of water are the root causes of black and odorous water. Under the action of aerobic microorganisms, the organic pollutants in the water consume a large amount of oxygen i...
