Method used for determining total mass of solid waste pile body

Abstract

The invention provides a method used for determining the total mass of a solid waste pile body. The method comprises the steps that the solid waste pile body is differentiated into n rectangular column bodies, and the stock volume of each solid waste column body is measured; the layered volume-weight of the highest column body is measured; based on the measurement result, neural network fitting is used to solve the non-linear distribution volume-weight of each layer; the average volume-weight of each solid waste column body is calculated; and by measuring the stock volume of each solid waste column body and the volume-weight of the solid waste column bodies, the total mass of solid wastes to be authenticated is calculated. According to the technical scheme of the invention, the total mass of the solid waste pile body can be measured simply, accurately and reliably, and the long-term leftover problem that the total mass of the solid waste pile body cannot be positively and directly determined is fundamentally solved.

Description

technical field [0001] The invention belongs to the field of environmental protection, in particular to a method for measuring the total mass of solid waste piles. Background technique [0002] The total mass of solid waste piles is the most important parameter to measure the basic properties of solid waste. Like the composition and content data of solid waste, it is an important data used to describe the basic properties of solid waste. In environmental protection work, it is frequently used in the following aspects: (1) in the identification of solid waste / hazardous waste in environmental protection, it is the only basis for determining the number of samples for identification objects; (2) in environmental protection design and management Among them, it is the basic measurement data of solid waste discharge, stacking, disposal, reduction, and comprehensive utilization; (3) In administrative law enforcement and judicial procedures, it is the basic data for measuring the sol...

Problems solved by technology

[0003] my country currently has a series of standards and norms for the identification and disposal of solid waste and hazardous waste, such as "Identification Standards for Hazardous Wastes" (GB5085.1-7-2007), "Technical Specifications for Identification of Hazardous Wastes" (HJ / T297-2007) , but these standards and norms have not yet mentioned a clear measurement method for the total mass of solid waste piles. In daily work practice, it is often used through production account statistics, or through process analysis and material balance. These two methods are highly dependent on data, and the usually accurate data is concealed by the parties (emission companies), which leads to large errors in the calculation results.

At present, the country and all parts of the country have not promulgated the volume measurement method of solid waste, the measurement method of solid waste bulk density, and there has been no corresponding mature and reliable technical method available for more than 20 years. The quality measurement of solid waste piles There are relatively large technical difficulties and technical bias in the field, and there is no ready-made and mature method to rely on
