A method for measuring the total mass of solid waste piles

Abstract

The invention provides a method for determining the total mass of a solid waste heap, which comprises the following steps: dividing the solid waste heap into n rectangular cylinders, measuring the storage volume of each solid waste cylinder; measuring the highest cylinder The layered bulk density, and according to the measurement results, use neural network fitting to solve the bulk density of the nonlinear distribution of each layer, so as to calculate the average bulk density of each solid waste column; by measuring the heap density of each solid waste column The storage volume and the bulk density of the solid waste column are calculated to obtain the total mass of the solid waste to be identified. By adopting the technical scheme of the invention, the total mass of the solid waste pile can be measured simply, accurately and reliably, and fundamentally solve the long-standing problem that there is no positive direct measurement method for the total mass of the solid waste pile.

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
