Vice Minister of Environmental Protection Zhang Lijun emphasized at the fifth inter-ministerial joint meeting of the province of Taihu Lake Basin Water Environment Management that the annual average concentration of total nitrogen in Taihu Lake has declined, but the situation facing the Taihu Lake Basin water environmental protection work is still facing. Still serious. This year, the Ministry of Environmental Protection will focus on six key tasks to improve the water environment in Taihu Lake. The six key tasks include: Further promote the reduction of the total amount of major pollutants. Strictly implement the emission reduction target responsibility system, and fully implement the various emission reduction measures; focus on the key industries and key areas of pollution reduction, guide the Taihu Lake Basin, two provinces and one city to formulate emission reduction plans in different categories; revise and improve the “Twelfth Five-Year Plan†Measures for the statistical monitoring and evaluation of major pollutants; Measures for the management of the total amount of major pollutants in new renovation and expansion projects. Control total nitrogen pollution and prevent eutrophication of the lake. Strictly examine and approve new projects for the release of total nitrogen, promote the prevention and control of agricultural non-point source pollution, and actively promote soil testing and formula fertilization. Strengthen environmental law enforcement supervision. Deeply carry out special campaigns to rectify illegal environmental protection enterprises to protect the health of the public, focus on monitoring the normal operation of pollution control facilities, and supervise and guide the prevention and control of heavy metal pollution in Taihu Lake Basin. Further improve risk response capabilities. Strengthen the emergency management of drinking water safety protection, and earnestly do a good job of the whole process of environmental emergency management of drinking water sources, including “previous prevention, forecasting and early warning, emergency preparedness, responding to events, and post-event managementâ€. We will strengthen monitoring and early warning of water environment in the Taihu Lake Basin. In order to do a mid-term evaluation of the "Overall Plan for the Comprehensive Management of the Water Environment in the Taihu Lake Basin," this year, the Ministry of Environmental Protection and the Ministry of Water Resources will jointly conduct joint water quality monitoring and assessment. To promote the "water special project" Taihu Lake project results. Further strengthen the integration with local pollution control projects, sum up and train a batch of key technologies and landmark achievements in water pollution control and treatment, give full play to the enthusiasm of local governments, and promote the results of “water special projects†in conjunction with relevant local government plans. Chromium(III) sulfate usually refers to the inorganic compounds with the formula Cr2(SO4)3.x(H2O), where x can range from 0 to 18. Additionally, ill-defined but commercially important "basic chromium sulfates" are known. These salts are usually either violet or green solids that are soluble in water. It is commonly used in tanning leather. Basic Chrome Sulphate,Basic Chrome Sulfate for Tannery,Tanning Agent Basic Chrome Sulfate Yucheng Jinhe Industrial Co.,Ltd , https://www.hntitaniumdioxide.com
Since 33% of the anion charges are due to hydroxy ions the basicity is 33% (but in tanning jargon it is known as 33% reduced). Products with higher basicities, e.g. 42% or 50% may be obtained by the addition of sodium carbonate, these are often used in combination with Sodium Formate. The sodium sulfate is often left in the technical product since it is inert with respect to the tanning process. It is important to fully reduce the hexavalent chromium to trivalent since the hexavalent is more likely to cause health problems for tanners and leather consumers.
The situation facing the water environmental protection work in the Taihu Lake Basin remains severe
