This year, the city has identified 10 key areas for comprehensive environmental improvement and watersheds. First, carry out comprehensive environmental improvement of Jialu River and Shuangyu River in Zhengzhou City, Shahe River Basin, and stop the production of key pollution sources that cannot be stably discharged to the Zhengzhou Hongda Paper Industry Corporation, and focus on the failure to meet the requirements of total control and water environment quality. The source of pollution is deeply treated. The second is to carry out comprehensive environmental improvement of the refractory industry in Xinmi City, shutting down 101 refractory enterprises and managing 496 within a time limit. The third is to carry out comprehensive environmental improvement of the refractory industry in Gongyi City, shutting down 85 refractory enterprises and controlling 269 companies within a time limit. The fourth is to carry out comprehensive improvement of the water environment of Jinshui River, Xiong'er River and Dongfeng Canal in the urban area, so that the water quality of Jinshui River and Xiong'er River will reach the landscape water standard this year; the water quality of Dongfeng Canal will reach the landscape water standard in 2007. The fifth is to carry out comprehensive improvement of atmospheric environment in Yangcheng Industrial Zone of Dengfeng City, focusing on the management of 30 enterprises in the smelting, electric power, carbon and refractory industries, and at the same time in heavy pollution industries such as Dengfeng Daye and Dongjindian new smelting. Remediation. The sixth is to carry out comprehensive environmental improvement of the carbon industry in Fuyang City, and comprehensively rectify all carbon and white corundum production enterprises within its jurisdiction. The carbon production roasting production line with coal as the direct fuel will be closed. The seventh is to carry out comprehensive environmental improvement in Chengbei District of Xinzheng City and to manage 64 enterprises. Eight is the comprehensive environmental improvement of Baisha Town Industrial Park in Zhongmu County, and 16 enterprises are governed.

The large-scale coal-fired boilers below 10 tons of steam in the service area of ​​the central heating pipe network will be demolished.
 Differential Pressure Sensor
Gamicos, aims to provide customers more options when they want to buy a product to measure object's pressure. Differential Pressure Sensor, also called differential transmitter or differential transducer, is used to measure the difference between two pressures, It can be used to measure the differential pressure of different medium like water, air, oil, gas, etc. The working principle of the differential pressure sensor is that the measured pressure directly acts on the diaphragm of the sensor, so that the diaphragm produces a small displacement proportional to the water pressure, so that the resistance value of the sensor changes, and the electronic circuit is used to detect this change, and convert the output of a standard measurement signal corresponding to the pressure.
