Embodiment 1

[0025] A method for treating sewage in garden planning, comprising the steps of: firstly, sewage (NH3-N is 147mg / L, sulfide 45mg / L, and P is 29mg / L) passes through a solid-liquid separator for solid-liquid separation, separation The solid is used to prepare fertilizer, the liquid enters the sedimentation tank, settles for 12 hours, then discharges the liquid into the microbial reaction tank, adjusts the pH of the liquid to 7, and adds 10 compound bacterial agents per cubic meter of liquid in the microbial reaction tank. gram, dosing once a day, continuously dosing for a week, and finally let it stand for 3 days, and drain the liquid for garden irrigation; the compound bacterial agent is prepared according to the following method: mix the bacterial liquid and the carrier of the bacterial agent at a ratio of 1:1 The weight ratio is mixed, stirred evenly, and then dried at a low temperature at 4°C, and the water content is controlled at 6% after drying to obtain final product; Th...

Embodiment 2

[0027] The sewage sample comes from a park sewage in Lanshan District of the city. First, the sewage is passed through a solid-liquid separator for solid-liquid separation. The separated solid is used to prepare fertilizer. The liquid enters the sedimentation tank and settles for 12 hours, and then the liquid is discharged into the microbial reaction tank , adjust the pH of the liquid to 7, add 10 grams of compound bacterial agent per cubic meter of liquid each time, add once a day, continue to add for a week, and finally let it stand for 3 days, drain the liquid for garden irrigation; compound bacteria The agent is prepared according to the following method: mix the mixed bacterial liquid and the carrier of the bacterial agent according to the weight ratio of 1:1, stir evenly, and then dry it at 4°C at a low temperature, and control the water content at 6% after drying to obtain the product; The bacterial agent carrier is obtained by mixing peat soil, diatomaceous earth and ch...

Abstract

The invention belongs to the field of landscape planning, and discloses a sewage treatment method in the landscape planning. The method comprises the four steps of: preparing a mixed microbial liquid; preparing a complex microbial inoculum; performing separation precipitation; and performing purification. The invention further discloses the complex microbial inoculum for sewage treatment. As the method is used, the sewage can be effectively treated. In addition, the method is simple and is low in cost, and realizes the purpose of turning waste materials into wealth.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a sewage treatment method in garden planning. Background technique [0002] Garden 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 garden construction projects. Landscape planning includes scenic area planning, urban green space system planning and park planning. The discharge of sewage in garden planning is a major difficulty in design. [0003] The sewage in the garden mainly includes domestic sewage and precipitation. The sewage produced in landscape gardens is mainly domestic sewage, so it contains a large amount of organic matter, etc., and is generally characterized by high nitrogen, sulfur and phosphorus content, which is harmful to garden trees and pollutes the environment. The b...
