Problems solved by technology

[0005] 1) The infiltration rate of garden planting soil is insufficient to timely discharge the runoff formed by heavy rain;
[0006] 2) There is no obvious removal function for runoff pollutants. On the contrary, the nutrients in the planting soil often pollute the downstream with the loss of water

Abstract

The invention relates to the field of urban runoff biodegration, in particular to a planting soil for a rainwater-regulation permeable tree pool and a preparation method thereof. The planting soil includes, by weight, 70-80 parts of sandy loam, 20-30 parts of coco coir, 5-10 parts of flay ash and 0.5-1 part of humus. The preparation method includes the following steps that 1, raw material treatment is conducted, wherein in the sandy loam treatment, sandy loam is taken, broken up and then air cured for 1-2 days, and a sterilizing agent is sprayed for sterilization after air-curing; in the coco coir treatment, coco coir is taken, soaked in water to make the conductivity of the coco coir lower than 0.5 mS / cm and then air cured for 1-2 days after dewatering, the coco coir needs to be turned three-four times during air curing, and then a sterilizing agent is sprayed for sterilization; in the fly ash treatment, the fly ash is taken, dried until the water content reaches 5%-8% and ground until the particle size is 0.1-0.2 mm; 2, the raw materials are blended, wherein the humus is taken to uniformly mixed with the sandy loam, the coco coir and the fly ash treated in the step 1. The planting soil can ensure the normal growth of plants, the permeation effect is good, and the removal effect of runoff contaminants is good.

Description

technical field [0001] The invention relates to the field of urban runoff biological retention, in particular to planting soil for rainwater regulation and storage infiltration tree ponds and a preparation method thereof. Background technique [0002] With the growth of urbanization, the population density of cities has risen sharply, which has continuously promoted the development of urban construction. While urban construction has made achievements, problems have also followed. Urban construction has changed the original natural ecological and hydrological characteristics of the city, and more than 70% of the precipitation is discharged as runoff, causing urban waterlogging. At the same time, urban runoff pollution is the second largest non-point source pollution after agricultural non-point source pollution. Atmospheric pollutants and road surface pollutants enter the water environment along with precipitation to form runoff, causing water pollution. At present, a seri...
