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 urban green land sewage treatment, the bacterial preparation is prepared from a mixed bacterial solution and a carrier at a weight ratio of 1:2, and the mixed bacterial solution is composed of actinomycetes, Alcaligenes, Bacillus pumilus, pseudomonas Preparation of Trichosaccharomyces, Bacillus jelly-like, Clostridium papyrisolubles, and Paracoccus denitrificans.

[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 jelly-like bacillus can specifically be jelly-like bacillus (Bacillus mucilaginosus) ACCC10013 (see CN103966149);

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

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

[0041] The carrier can be a solid carrier and / or a li...

Embodiment 2

[0049] The urban green space sewage sample comes from a park sewage in the city, and it is treated according to the following steps

[0050] (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=6:4:4:8:5;

[0051] (2) Filtration: filter the sewage treated in step (1) to obtain filtrate and sludge, the filtrate enters the secondary sedimentation tank, and settles for 8 hours, adding 1% by weight coagulant in the secondary sedimentation tank;

[0052] The coagulation aid is composed of the following components by weight: polyacrylamide: FeCl3: pullulan: bentonite=3:2:3:4, the present invention optimizes and improv...

Abstract

The invention belongs to the field of sewage treatment, and relates to a microbial preparation for urban green land sewage treatment and a using method thereof.The preparation is prepared from mixed bacterium liquid and a carrier according to the weight ratio of 1:2, wherein the mixed bacterium liquid is prepared from actinomycetes, alcaligenes, bacillus pumilus, candida mycoderma bacteria, bacillus mucilaginosus, clostridium papyrosolvens and paracoccus denitrificans.According to the microbial preparation and the using method thereof, various bacterium strains which can form dominant bacterial communities are prepared into the efficient microbial preparation, and the sewage treatment effect is good.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a microbial preparation used for urban green land sewage treatment and a use method thereof. Background technique [0002] Urban green space planning 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. Plants with different ecological characteristics can have their own places, 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. It is the embodiment of human material and The inevitable result of the development of spiritual civilization. Landscape planning refers to the activities of comprehensively determining and arranging the nature, scale, development direction, main content, infrastructure, spatial comprehensive layout, construction...
