Recently,The Hubei Provincial Environmental Protection Committee Office announced the list of the first batch of provincial-level "zero-waste cities"., respectively: Jingmen, Ezhou, Xiaogan, Xiantao and Qianjiang. At the same time,Anhui Province has also recently announced a zero-waste city promotion planIn December 2023, a provincial-level "zero-waste city" joint conference system will be established, and the construction of a "zero-waste city" in the province will be fully carried out in 2025. Cities such as Wuxi and Suqian in Jiangsu Province have also emphasized the construction of "zero-waste cities".Using modern equipment and intelligent means, we will continuously strengthen solid waste treatment and waste reduction. At the same time,Shanghai, Guangdong, Sichuan, Henan, Shandong and other provinces and citiesAll of them have issued documents indicating that they are accelerating the construction of "zero-waste cities".
What is a "zero-waste city"?
A zero-waste cityIt is not completely eliminated from the generation of waste"Waste" mainly refers to solid waste, which is generally divided into domestic waste, construction waste, industrial solid waste, medical waste and agricultural waste, etc., and can be divided into hazardous waste and ordinary waste according to the degree of harm. A zero-waste cityConstruction is to effectively use solid waste, reduce solid waste generation, solve the historical storage of solid waste, and ensure a virtuous cycle.
How can leachate treatment promote the construction of a "zero-waste city"?
As an eco-friendly company, we are well awareLandfill leachate treatmentIt is an important part of the construction of a "zero-waste city". On the one hand, landfill leachate treatment can reduce the pollution of garbage to the environment and protect the ecological environmentMeet the harmless treatment；On the other hand, the treated landfill leachate can be reused as a resource, such as for agricultural irrigation, ecological landscape construction, etc., to realize wasteReduction and recyclingExploit.
Landfill leachate treatment equipment to ".Efficient physicochemical + enhanced biochemistry"The craft, by building".Bacteria-enzyme-active carriersThe composite system greatly improves the activity and oil resistance of the biochemical system, so that the removal efficiency of organic matter, ammonia nitrogen and total nitrogen meets the emission requirements, and the leachate is fully discharged up to the standard without using membrane separation technology. The full quantification of landfill leachate treatment is fully in line with the core meaning of "zero-waste city", that is, recycling, reduction and harmlessness.
InXincai County, Henan ProvinceDaze Environmental Protection cooperates with Everbright EnvironmentIncineration plant leachate treatmentproject, landfill leachate of the projectThe daily output is 300 tonsAfter the leachate purification treatment by Daze Environmental Protection, the effluent quality reaches the supplementary water quality of the open circulating water system in the GB19923-2005 "Urban Sewage Recycling - Industrial Water Quality" standard, which can be usedUtilization of urban renewable water resources
InChizhou, AnhuiThe kitchen waste disposal center was also jointly completed by Daze Environmental Protection and EverbrightFood waste leachate treatmentproject, adoption"Pretreatment + Wastewater Treatment + Odor Treatment".and other technological processes, "eating" garbage, "spitting out" crude grease and biogas,The extracted crude oil is entrusted to a qualified unit for resource utilization。Generated during the pre-treatment processSolid residue, biogas and odor enter the domestic waste incineration plant for incineration。The leachate of food waste enters the leachate treatment station for treatment, and the final effluent needs to meet the requirements of the supplementary water quality of the open circulating water system in the standard of "Urban Sewage Recycling - Industrial Water Quality" (GB19923-2005).Realize green and harmless recycling treatment
Daze environmental protectionHe has been deeply engaged in the field of leachate treatment for many years, and has been constantly breaking through innovative process technology to solve leachate treatment problems for various localities and enterprisesRecycling, reduction, and harmlessnessImprove the ecology of urban water quality and help build a green and beautiful "zero-waste city"!
