Problems solved by technology

[0007] In order to solve the problem of traditional black and odorous water treatment, the purpose of the present invention is to provide a method for purifying black and odorous water. Through the reconstruction of the ecological system, the self-purification ability of the water body can be restored, and the odor and chromaticity of the black and odorous water can be gradually eliminated. Ornamental entertainment value of restored water bodies

Embodiment 1

[0039] The present embodiment provides a method for purifying black and odorous water bodies. Calcium peroxide slow-release granules (which are compounded and pressed by 50% magnesium carbonate and 50% calcium peroxide) are sprinkled in batches in the black and odorous river course. The dosage is 10g / m 2 , dosing once a day, monitor the ORP of the sediment area after each dosing, when the ORP increases to more than 100mv, add 0.5g / m2 to the water body 2 Biological enzyme preparation (including starch hydrolase granules, cellulose hydrolase granules, polysaccharide hydrolase granules, proteolytic enzyme granules and lipase granules compounded according to the ratio of 3:4:2:1:1), used to activate Bacteria and spores in the sediment decompose the surrounding organic matter. After 15 days, add sulfide bacteria compound preparation granules (a granule preparation made by mixing Thiobacillus beinii and Thiobacillus in a ratio of 1:1) to the water body at 3 g / m 2 , for the decompo...

Embodiment 2

[0044] The present embodiment provides a method for purifying black and odorous water, in which calcium peroxide slow-release granules (which are compounded and pressed by 30% magnesium carbonate and 70% calcium peroxide) are sprinkled in batches in black and odorous ponds, each The dosage is 5g / m 2 , dosing once a day, monitor the ORP in the sediment area after each dosing, when the ORP increases to more than 100mv, add 1g / m2 to the black and odorous pond 2 Biological enzyme preparation (including starch hydrolytic enzyme granules, cellulose hydrolytic enzyme granules, polysaccharide hydrolytic enzyme granules, proteolytic enzyme granules and lipase granules compounded according to the ratio of 3:3:3:2:1), used to activate Bacteria and spores in the sediment hydrolyze the surrounding organic matter. After about 15 days, add sulfide bacteria composite preparation granules (a granule preparation made by mixing Thiobacillus beinii and Thiobacillus in a ratio of 1:1) to the blac...

Abstract

The invention provides a black and odorous water body purifying method. The black and odorous water body purifying method comprises the following steps: adding alkali metal peroxide slow-release particles at the bottom of the water body by batches; adding bio-enzyme preparation particles at the bottom of the water body; adding sulfured bacteria composite preparation particles on the surface of thewater body; uniformly dispersing and adding the alkali metal peroxide instant particles on the surface of the water body by batches; adding high-efficiency degraded bacteria liquid in the water body,simultaneously, arranging aeration oxygenation equipment on the surface of the water body or a superficial layer for continuous reoxygenation of the water body; and placing fish in the water body and / or planting water plants at the near shore of the water body for biological treatment to realize purifying and good ecological circulation of the black and odorous water body. The black and odorous water body purifying method has the advantages of less engineering measures, less construction engineering work, and little environment secondary pollution, through re-construction of an ecological system, the water body self-cleaning capability is recovered, and peculiar smell and chroma of the black and odorous water body are gradually eliminated, so that the ornamental entertainment value of thewater body can be recovered from the senses.

Description

technical field [0001] The invention belongs to the technical field of water quality treatment and relates to a method for purifying black and odorous water. Background technique [0002] Black and odorous water bodies have a certain impact on the urban environment, social features, and residents' physical and mental health. The treatment of black and odorous water bodies has become a key issue in urban environmental improvement. There are two sources of pollutants in black and odorous water bodies: internal pollution and external source pollution. The traditional treatment of black and odorous water bodies generally takes various engineering measures, such as interception, pumping, excavation, and sediment dredging, to remove black and odorous water from The bottom mud is removed, and then new water is injected into the water body, and the discharge of exogenous pollutants around the water body is controlled, or the black and odorous water body is degraded by adding microbi...
