Branch run for the biological treatment of sludge treatment industry introduced the relevant policies and standards

Release date:2017-01-13 Author:青岛科润生物科技 Click:

We should not understand the laws and regulations of the sludge treatment industry, today, Qingdao Branch Run biological and everyone together to learn about. China's sludge treatment industry has just started, the relevant policies and regulations, standards and management system is not perfect.

1, in twentieth Century 60-70 China's sewage treatment plant is less, the main land use, the use of mesophilic anaerobic digestion, technology and equipment almost all imports. To guide the use of sludge in agriculture, in 1984 China's urban and rural construction ministry of environmental protection issued a "sewage sludge pollution control standards" (GB4284-84). The standard of limit of harmful substances in the sludge, and the provisions of the sewage sludge period, to a certain extent to the safety of agricultural sludge initially gave guidance; however, the standard age, can not guarantee the safe utilization of sludge land. And the lack of long-term monitoring of agricultural sludge in china. In July 17, 1993, the former Ministry of Construction issued the "city sewage treatment plant sewage sludge discharge standard" (CJ3025-93), the city sewage treatment plant sludge discharge standard has been stipulated, the text of the requirements of the city sewage treatment plant sludge should be dehydrated, the water content is less than 80%.

2, in 2000, the Ministry of construction, the State Environmental Protection Administration, Ministry of science and technology jointly issued the "urban sewage treatment and pollution control technology policy". The treatment of sludge is put forward. The municipal sewage treatment sludge should be treated by anaerobic, aerobic and composting methods. After the treatment of sludge, to achieve stable and harmless requirements can be used in farmland, or should be in accordance with the relevant standards and requirements for sanitary landfill disposal.

In 2002, the State Environmental Protection Administration and the State Bureau of technical supervision and inspection approved the release of "urban sewage treatment plant pollutant discharge standards" (GB18918-2002). The standard provides the stability of sludge after anaerobic digestion or index: both aerobic digestion of organic matter degradation rate is greater than 40%; and further provides the moisture content, worm egg mortality, fecal coliform value limit.

3, after 2007, the state to further strengthen the management of sludge treatment and disposal. Environmental Protection Administration launched the "construction" of environmental technology management system, and one of the six major industries of sewage sludge is included in the first batch of pilot, and in early 2008 released a "best available technology for disposal of sewage sludge treatment of city sewage treatment plant" (draft).

4, in order to speed up the construction of standard system for disposal of sludge treatment in China, approved by the State Administration of quality and technical supervision, in the specific management of the Ministry of housing, the establishment of the national urban sewage sludge treatment and disposal Standardization Technical Committee, responsible for municipal sewage sludge treatment and disposal standards and centralized management. Lasted nearly 4 years, issued a total of 9 industry standards.

5, 2009, the Ministry of housing and urban rural development and promulgated the "urban sewage treatment plant sludge treatment technical regulations" (CJJ 131-2009) (record number J891-2009). In February of the same year the Ministry of construction, Ministry of environmental protection and the Ministry of science and technology jointly issued the "sludge treatment and disposal technologies of pollution prevention and control policy of urban sewage treatment (Trial)", the technology policy clear technology roadmap for sludge treatment and disposal regulations, implementation of sludge disposal and comprehensive utilization in safety, environmental protection and economy of the at the same time, the provisions of the safeguard measures for sludge treatment and disposal; on the other hand, put forward the financing mechanism of sludge treatment and disposal, is conducive to the development of the market of sludge.

6, in order to give guidance on the sludge treatment and disposal technology in February 2010, the Ministry of environmental protection issued the "urban sewage treatment plant sludge disposal and pollution control of best available technology guide" (Trial), selected the best available technology for sludge treatment and disposal. The introduction of technical policy and the guide of the best feasible technology has pointed out the direction for the sludge treatment and disposal of the urban sewage treatment plant in our country, and will promote the development of sludge treatment and disposal in our country to a great extent. November 2010, the Ministry of environmental protection issued on the strengthening of urban sewage treatment plant sludge pollution prevention and control work, requiring local governments at all levels to speed up the construction of sludge treatment facilities;

7, March 2011, the national development and Reform Commission and the Ministry of housing jointly issued "on the further strengthening of sludge treatment and disposal work organization and implementation of demonstration projects of the notice", requiring all departments attach great importance to sludge treatment and disposal work. In March 14, 2011, the Ministry of housing and the development and Reform Commission jointly issued the "urban sewage treatment plant sludge treatment and disposal of technical guidelines (for Trial Implementation)" (No. 34) (hereinafter referred to as the "guide"). The sludge of a sewage treatment plant in most of our towns are not harmless disposal and resource utilization status relatively lags behind, the "guide" for the urban sewage treatment plant sludge treatment and disposal work from the general, the origins and characteristics of sludge, sludge treatment and disposal technology route and scheme, sludge disposal and related technology, emergency disposal the risk management and other aspects of the planning.

Planning: mainly reflected in the national urban sewage treatment and recycling facilities construction plan, to pay attention to the safe disposal of sludge as one of the four major tasks, and made a general rule and prediction of sludge production, disposal and investment. , "12th Five-Year" sludge treatment and disposal facilities to invest 31 billion 200 million yuan, the average of more than the provincial capital of more than 36 cities and municipalities harmless disposal rate of sludge reached an average of more than 70%, the new sludge daily processing capacity of 47 thousand tons / day.

Today and the small series together to learn the relevant national policy is not very useful. For more information, please continue to pay attention to Qingdao Branch Run Biotechnology Co., Ltd., a professional manufacturer of corrosion inhibitors.
