Embodiment 1

[0025] There is a green plant waste disposal site at the junction of a city and suburbs. With the expansion of the city, the green plant waste disposal site that was far away from the residential area has been surrounded by the residential area at a distance of 200m. There is no special design for the functional area of ​​the green plant waste disposal site. It uses open-air composting, which is noisy, dusty, and infiltrated water flows randomly, attracting mosquitoes and flies. The operating conditions are poor; and due to gas emissions during the composting process, although The smell is not very strong, but a smell of putrid mold can waft into the residential area, and residents have been complaining.

[0026] A method for controlling the environmental quality of green plant waste disposal sites:

[0027]1. Prospect and re-layout the entire green plant waste site: the area of ​​the green plant waste disposal site is about 6000m 2 , the amount of green plant waste disposal ...

Embodiment 2

[0045] Status quo: A first-tier city has established a green plant waste disposal site with an annual processing capacity of 15,000 tons in a corner of its botanical garden. Due to the special government funding in the early stage, the site has been planned and 5 buildings with a length of 15m and a width of 4m have been established. The adjacent plastic greenhouse is used for composting; another room has been built separately for crushing. However, the overall layout is chaotic, and the loud sound of crushing has caused complaints from tourists in the botanical garden; the overall environment of the site is not optimistic, especially in summer, it is easy to breed mosquitoes and flies, which has become a dead corner of the botanical garden. To this end, the entire site environment needs to be improved.

[0046] A method for controlling the environmental quality of green plant waste disposal sites:

[0047] 1. According to the existing layout of the botanical garden disposal ...

Abstract

The invention discloses a system and a method for controlling the environmental quality of a green plant waste disposal site. The control system comprises an isolating room and a compost room, whereinspraying devices are arranged at the top of the isolating room and the top of the compost room respectively; a soaking pond is arranged at the bottom of the isolating room; a ventilation system and an infiltration device are further arranged inside the compost room; and the infiltration device is connected with an adsorption pond or a filter, an infiltration pond and a soaking pond in sequence. The control method comprises the following steps: exhausting waste gas inside the compost room through the ventilation system; enabling infiltration liquid to enter the adsorption pond or the filter through the infiltration device, and then entering the infiltration pond; opening a water pump when required, and carrying out spraying; enabling the infiltration liquid overflowing inside the infiltration pond to enter the soaking pond so as to mix and soak a green plant waste smashed material. Through layout optimization and functional integration of each functional area of the site, the whole green plant waste disposal site reaches the environmental requirement of clean and safe quasi-industrialization production workshops.

Description

technical field [0001] The invention relates to a system and method for controlling the environmental quality of green plant waste disposal sites, in particular to a system and method for the construction and environmental quality control of organic waste composting sites mainly based on green plant waste, which belongs to solid waste Disposal technology field. Background technique [0002] Greening plant waste refers to the litter waste produced by natural regeneration during the growth of greening plants or the trimmings of trees and shrubs (thinning), lawn trimmings, discarded grass flowers and weeds in gardens and flower beds, etc. Vegetable waste material. In recent years, with the rapid development of urban greening, green plant waste has become another important urban solid waste after domestic waste. Taking Shanghai as an example, the total amount of tree branch trimmings in built-up areas alone is about 700,000 tons per year. If the green area of ​​Shanghai’s buil...
