slurry preparation system, the processes of transportation, feeding, ash separation and silo are fully enclosed, and the pulping process is equipped with ash and dehumidification devices. The SO 2 in the waste gas of the rotary kiln is treated by limestone - gypsum method and discharged from the 110m high chimney at high altitude; the emission concentration of SO 2 and unorganized dust can meet the emission limit requirements of (GB4915-2013 ) "Comprehensive Emission Standard for Air Pollutants in Cement Industry.
(2) Water Environment Pollution Prevention and Control Measures
Project Drainage is divided into rain and sewage, and rainwater ditches (cement hardening) are set up. Rainwater at the project site enters the existing rainwater system in the plant area. Drainage ditches and water collecting tanks are built, equipped with cyclone machines and filtrate collection tanks. The wastewater is collected by the water collecting tanks and recycled for production without external discharge; A 570m 3 accident slurry tank has been built. The slurry discharged from the absorption tower during the accident will be collected in the accident slurry tank and recycled to the absorption tower without being discharged outside, thus having little impact on the outside world.
(3) noise prevention measures
project noise mainly comes from production equipment such as fans and water pumps, equipment is low noise equipment; The fans and pumps are all placed in closed compartments, and measures such as vibration reduction, noise elimination and distance attenuation are taken.
(4) Solid Waste Pollution Prevention Measures
The solid wastes discharged during the operation period of the project are mainly domestic garbage and desulfurization gypsum. A standardized temporary storage room for solid waste is built on the first floor of the desulfurization station. The dehydrated gypsum is collected by the temporary storage room and regularly transported to the gypsum storage yard in the plant area. As raw material, it enters the cement mill and is not discharged. Domestic waste is uniformly removed and transported by the local environmental protection department for centralized treatment.

Two Cement Enterprises Start to Implement "Big Patrol Inspection"
With the change of the competition situation in the industry, the profit space of cement production enterprises has been greatly squeezed. Reducing costs and increasing efficiency and job optimization have become the inevitable choice to improve the enterprise's own development ability and enhance the core competitiveness. In accordance with the requirements of the group company to realize the transformation from extensive management to lean management, combined with the advanced experience of peer enterprises, recently, Yunnan peak, daye peak two enterprises have implemented "big inspection" to promote the overall optimization of posts. On November 1, daye peak post inspection officially started full operation, starting from the limestone storage yard at the source of the production line to the cement storage. the original 15 posts were merged, and the best experienced mechanics, electricians and post workers were transferred to form a large inspection class, which was mainly responsible for on-site emergency disposal and post routine maintenance to ensure the normal production of the whole production line. In order to ensure the smooth implementation of the large-scale inspection, daye peak management team has repeatedly communicated and discussed with the heads of relevant workshops and departments, and held a special workshop post optimization promotion meeting in September to clarify objectives and responsibilities, formulate implementation steps, and do a lot of preparatory work. At the kick-off meeting for the implementation of the large-scale inspection on October 31, Zhang Fengliang asked daye peak employees to recognize the current situation of serious cement overcapacity and cruel market competition, understand the necessity of implementing the large-scale inspection, and asked the workshop leaders to do a good job in training and guiding the employees, shorten the transition period, normalize the operation of the large-scale inspection as soon as possible, and at the same time, managers should also change their working ideas and concepts and do a good job in full-time, strengthen the inspection, overhaul and maintenance of the regular day shift, and find and solve the problems existing in the equipment and process in time.
