Efficient fertilizer contributing to reduction of accumulation of chromium heavy metal pollutant in vegetable and preparation method of fertilizer

The invention discloses an efficient fertilizer contributing to reduction of accumulation of a chromium heavy metal pollutant in a vegetable. The fertilizer comprises the following components, by weight part: betaine, activated nanometer attapulgite, rice bran, powder or fermented substances of stem-type vegetables with strong fiber, cationic chitosan, germinated brown rice, microzyme, melatonin, an anion-modified macro-molecule chitosan heavy metal adsorbent, and a proper amount of mineralized micromolecule activated water. Melatonin and betaine treated with mineralized micromolecule activated water match activated nanometer attapulgite to prepare factors for self-cleaning of a chromium heavy metal. The factors easily enter the inside of cells, quickly participate into living movement of plants, promote plant bodies to absorb and utilize heavy-metal-chromium-type substance, and further promote living movement of the bodies, thereby reducing pollution. The fertilizer matching a nutrient solution treated through mineralized micromolecule activated water, and main materials can effectively convert heavy metals left in the vegetable, thereby having a function of self-cleaning of heavy metals.

Waste heat recovery product well system for ISC and operation method thereof

The invention provides a waste heat recovery product well system for ISC and an operation method of the waste heat recovery product well system for the ISC. The waste heat recovery product well system for the ISC comprises a product pipe, a jacketed pipe, a water cooling pipe, a monitoring instrument system, a product well bushing, a high-temperature high-pressure wellhead device, a ground waste heat recovery device and the like. Each component in the product well system is easy to recycle and reutilize. Heat carried out by high-temperature high-pressure downhole steam can be used for the ground production technology, turbine power generation, boiler power generation, other ground public facilities or plant life purposes and the like. By the adoption of the waste heat recovery product well system for the ISC and the operation method of the waste heat recovery product well system for the ISC, effective monitoring, control and protection of a product well can be achieved, waste heat of high-temperature crude synthesis gas is reliably and effectively recycled and comprehensively utilized, the consumption of cooling water is significantly reduced, and the requirement for downstream waste water treatment is lowered, comprehensive and efficient utilization of coal is achieved, the energy consumption of the whole ISC is lowered, and the technical problems faced by the existing ISC are finally solved.
