Problems solved by technology

The disadvantage of this treatment device is that impurities such as mud and sand in the sewage can easily block the first filter plate and the second filter plate in the sewage treatment area, greatly reducing the treatment efficiency; the device only treats sewage by filtering, and cannot effectively Removes fine particles, microorganisms and odors in sewage, and the treatment effect on sewage is poor

Embodiment 1

[0033] A microbial preparation for sewage treatment, the microbial preparation includes a mixed bacterial liquid and a carrier, the mixed bacterial liquid is composed of actinomycetes, Alcaligenes, Bacillus pumilus, Candida, Bacillus amyloliquefaciens, lysobacter Clostridium papyrus, paracoccus denitrification preparation.

[0034] The actinomycete is Actinomycesnaeslundii ATCC19246;

[0035] The Alcaligenes sp. is ATCC31555

[0036]The Bacillus pumilus is Bacillus pumilus ATCC27142;

[0037] The Candida bacterium is Candida utilis ATCC No.22023;

[0038] The Bacillus amyloliquefaciens is (Bacillus amyloliquefaciens) ATCC23843;

[0039] The Clostridium papyrosolvens is (Clostridium papyrosolvens) ATCC700395;

[0040] The paracoccus denitrificans can specifically be Paracoccus denitrificans ATCC13543;

[0041] The carrier is composed of the following raw materials: diatomaceous earth and chitosan.

[0042] Preferably, the carrier is formed by mixing diatomaceous earth and...

Embodiment 2

[0048] The sewage sample comes from a park sewage in the city, and it is processed according to the following steps

[0049] (1) The sewage is flowed to the primary sedimentation tank by itself, and the sinkable and floating objects are filtered out. The primary sedimentation tank contains 2% by weight (to the weight ratio of the primary sedimentation tank sewage) of the sedimentation aid, and the sedimentation aid is It consists of the following components by weight: diatomite: calcium hydroxide: quartz sand: activated carbon: ferrous sulfate=5:3:3:7:4;

[0050] (2) Filtration: filter the sewage treated in step (1) to obtain filtrate and sludge, the filtrate enters the secondary sedimentation tank, and settles for 5-10 hours, adding 1% weight coagulant in the secondary sedimentation tank;

[0051] The coagulant aid is made up of the following components by weight: polyaluminum chloride: FeCl3: pullulan: bentonite=2:1:2:3, the present invention optimizes and improves the coagu...

Abstract

The invention belongs to the technical field of environmental protection, and discloses a sewage treatment method for garden planning. The sewage treatment method comprises the following steps: performing treatment through a preliminary sedimentation tank; performing filtration; performing secondary precipitation; performing treatment by a biological reaction tank. Mixed bacterium liquid being prepared from actinomycetes, bacillus alcaligenes, bacillus pumilus, candida albicans, bacillus amyloliquefaciens, papyrosolvens and paracoccus denitrificans is added into the biological reaction tank, sewage treatment is performed, 10 grams of a microbiological preparation is added into each cubic meter of liquid each time, adding is performed once every day and continually performed for one week, and finally standing is performed for 3 days, so that liquid is drained for garden irrigation. The method disclosed by the invention is suitable for sewage treatment of gardens, and treated water can be used for greening of communities and gardens, sprinkling to roads and the like, so that circular economic utilization of water is realized.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a sewage treatment method in garden planning. Background technique [0002] Ecological garden refers to the garden green space system built under the guidance of ecological principles. In this system, ecological tribes composed of trees, shrubs, herbs, vines, etc. are coordinated among the populations, and there are compound levels and suitable seasons. Color, plants with different ecological characteristics can have their own place, make full use of sunlight, air, land, nutrients, water, etc., to form a harmonious, orderly and stable community, it is the highest level of urban landscaping work, and it is the material and spiritual quality of human beings. The inevitable result of the development of civilization. Landscape planning refers to the activities of comprehensively determining and arranging the nature, scale, development direction, main content, infr...
