Some embodiments of the invention provide a method of automatically bundling environmental conservation items with computed environmental conservation values into “credit blocks” so that the aggregate sum of the environmental conservation values of the items in a particular block is sufficient to issue a tradable environmental commodity. Some embodiments bundle all environmental conservation values associated with the registrations of a particular registrant. The registrant may then subsequently withdraw from his / her individually bundled environmental conservation in order to directly offset some polluting activity without having to purchase credits. Some embodiments provide distributed bundling by allocating a fractional portion of an environmental conservation value produced from a registered item to at least two separate entities.

The invention belongs to the technical field of an environment protection technology, and particularly relates to a method for repairing the water quality of river based on a system coupling mode. According to the method, a river bank vegetation belt system, a multifunctional pond system and a riverway bottomland micro-landform transforming system can be organically coupled with one another, so that a coupling match system can be formed. Compared with a single subsystem, the coupling match system is more complex in inner tissue and more reasonable in structure, and has the functions of strengthening the whole function of the system and amplifying the whole benefit of the system; and the water quality of the river, the structure of a river ecosystem, the quality of the biological habitat and the whole current situation of the biological environment can be effectively improved, and the physical, chemical and biological integrity of the river ecosystem can be enhanced, so that the methodis a river repairing mode 'which is near to the nature, multifunctional, high in benefit and sustainable'. The water resource can be sufficiently used, the economic benefit can be increased, and the contradiction between the environmental protection and the economic growth in the wide rural area can be effectively remitted.

The invention relates to a two-section rotation oxygen-enrichment external heating oxidation technology and device for dry-method and semi-dry method desulfurized ash. A two-section type rotation oxidation kiln is adopted, oxygen is introduced into the kiln and heating is implemented by adopting an external heating furnace, so that the oxidizing process for converting CaSO3 in the desulfurized ash into CaSO4 is completed. Compared with the prior art, the technology and the device have the benefits as follows: (1), during the oxidation of the desulfurized ash in the oxidation kiln, stable oxidation time, balanced oxidation temperature, sufficient oxygen content and appropriate oxidation atmosphere are realized, the technical measures such as automatic control, surplus heat utilization, dust removal and environment protection are adopted, so that the low-cost oxidation and industrialized production are realized; (2), the provided systematic desulfurized ash oxidation production line is suitable for the industrialized and large-scale production requirements; (3), the processing parameters such as oxidation temperature, time and oxygen content are controlled through a PC (Personal Computer), so that the appropriate oxidation conditions are ensured; (4), the promotion of the development of a dry-method and semi-dry method desulfuration technology is facilitated; (5), the resource utilization of the desulfurized ash is realized, and the energy conservation, emission reduction and environment protection are facilitated.

The invention develops a plasma treatment method using a gas free of a greenhouse effect in order to realize the global environmental preservation, and the plasma process of high performance, the invention also provides a plasma etching method which inhibits a damage to a device, and has high accuracy. The plasma processing method according to the invention comprises following steps: supplying a treatment gas containing a fluorine gas (F2) into a plasma producing chamber, repeating applying / its stopping of a high frequency electric field alternately to generate a plasma, and irradiating the plasma on a substrate to carry out the substrate treatment. Further, the substrate processing can be performed as following: a neutral particle beam is produced by extracting a negative ion or a positive ion from the plasma separately individually, or alternately by extracting only a negative ion selectively to neutralize the plasma, and the neutral particle beam is irradiated to the substrate.
