Zhang Zuochen, vice president of the China Geological Environment Monitoring Institute, disclosed in Beijing on the 29th that after the implementation of the current groundwater quality standards for nearly 20 years, the official plans to amend it. At present, the first draft of the new standard has been completed and will be issued after being reviewed by the National Standardization Management Committee.

The pl series batching machine used in this product consists of a feeding mechanism, a weighing system, an electrical control system and other components. The structure of the batching machine is arranged in a "good" shape, which is conveyed by a belt conveyor and weighed by a plurality of sensors for accurate measurement.
This product Screw Conveyor is a double pitch blade that reduces the degree of compression of the material during transport. It is equipped with high-quality medium-hanging bearings and is easy to install.
This product(concrete batching plant) is equipped with the storage, batching, conveying, stirring, control and other devices of various raw materials required for precast concrete, and various aggregates, powders, admixtures, water, etc. A complete set of equipment for supplying concrete in a concentrated manner than by a mixer.
1.It is assembled by building blocks, which is short, quick and convenient.
2.It is convenient and quick to use the cylinder discharge or electric push rod to discharge.
3.A variety of mixing processes, highly automated, high production efficiency,
4.Environmental protection and energy saving, using pulse dust removal, recycling waste-water for reuse

The current groundwater standard implemented in China was established in 1993. At the press briefing held by the Ministry of Land and Resources on the same day, Zhang Zuochen stated that as China’s economic and social development and understanding of groundwater conditions continue to deepen, the standard needs to be revised.
He said that taking into account the effects of national human engineering activities on groundwater environment in the past 20 years, the new standard will increase and revise some specific standards and will be more perfect than existing standards.
Regarding the current status of groundwater monitoring in China, Zhang Zuochen disclosed that as of the end of 2013, there were approximately 16,000 groundwater monitoring sites of all types and levels in China, with a monitoring area of ​​approximately 1.1 million square kilometers, including 2,000 water level flow monitoring sites, and a national groundwater monitoring network. The construction started to take shape. However, there are still many problems such as the lack of national-level groundwater monitoring points, low level of automation monitoring, low monitoring capacity, and failure to meet the requirements of economic and social development.
To this end, relevant departments such as the Ministry of Land and Resources and the Ministry of Water Resources have already deployed national groundwater monitoring projects in the next three years. Among them, the Ministry of Land and Resources will establish 103 national groundwater monitoring sites. After completion, water will be collected, water testing will be carried out, and automatic collection and monitoring of data such as water level and water temperature will be achieved.
The above-mentioned new construction combined with the existing groundwater monitoring station network can form a relatively complete national-level groundwater monitoring station network, providing timely, accurate, and comprehensive groundwater dynamic information for the society.
The Ministry of Land and Resources promulgated the "Measures for Geological Environmental Monitoring and Management" this year and will implement it on July 1. It includes monitoring of geological environment such as groundwater, geological disasters, and mines.
According to reports, this policy has relevant provisions in the aspects of organizational implementation, network construction and monitoring results, and also clearly defines the major responsibilities of the land and resources authorities at all levels.
