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

[0036] The Alcaligenes sp. is ATCC31555

[0037] The Bacillus pumilus is Bacillus pumilus ATCC27142;

[0038] The Candida bacterium is Candida utilis (Candida utilis) ATCC No.22023;

[0039] The Bacillus amyloliquefaciens is (Bacillus amyloliquefaciens) ATCC 23843;

[0040] The Clostridium papyrosolvens is (Clostridium papyrosolvens) ATCC 700395;

[0041] The paracoccus denitrificans can specifically be Paracoccus denitrificans ATCC13543;

[0042] The carrier is composed of the following raw materials: diatomaceous earth and chitosan.

[0043] Preferably, the carrier is formed by mixing diatomaceous earth and chitosan in a ...

Embodiment 2

[0049] The sewage sample comes from a park sewage in the city, and it is processed 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 aid 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 improves the coagu...

Abstract

The invention relates to a sewage treatment method used in the urban green space planning. The sewage treatment method includes the following steps that filtration is performed in a primary sedimentation tank, secondary sedimentation is prformed in a biological reaction tank, mixed bacterial liquid prepared by actinomyces, alcaligenes, bacillus pumilus, candida mycoderma bacteria, bacillus amyloliquefaciens, clostridium papyrosolvens and paracoccus denitrificans is put in the biological reaction tank for sewage treatment, 10 grams of a microbial preparation is put in per cubic meter of liquid for one time every day, putting continues for one week, finally standing is performed for 3 days, and the liquid is discharged out for garden irrigation. The sewage treatment method is suitable for garden sewage treatment, treated water can be used in communities and used for landscaping, road watering and the like, and cyclic economical water utilization is achieved.

Description

technical field [0001] The invention belongs to the technical field of microbes, and in particular relates to a method for treating sewage in urban green space planning. 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 phases and investment estimation of la...
