The invention provides an ecological treatment system and method for cold-rolling reverse osmosis strong brine. The treatment system comprises a water inflow pipe, a water inflow tank, a water distributing partition plate, a water inflow gravel commutating zone, fly ash ceramsite filler, manganese sand filler, a sand bed layer, an anti-seepage layer, modified montmorillonite filler, covering soil, plants, a water outflow gravel commutating zone, a water outflow tank, a water outflow liquid level control part and a water outflow pipe. The ecological treatment system is used for treating the reverse osmosis strong brine, one-time investment is low, running and operation are easy, and production and treatment cost is low; after the cold-rolling reverse osmosis strong brine is treated through the ecological treatment system, COD and total nitrogen of outflow water are lower than the national emission standard, various kinds of heavy metal in the strong brine can also be efficiently removed, and the ecological treatment system is an environment-friendly steel and ion waste water treatment technology.

The invention provides a method for producing three-dimensional network solidification and sealing carbonaceous ceramsite by hot dipping of leather sludge. Then put it into a cracking furnace, and thermally crack it in isolation from air at 300-800°C until no cracking gas is produced, forming carbonaceous ceramsite with a large number of micropores on the surface; then impregnated in the impregnated material, using carbon The temperature of the ceramsite itself melts the impregnated material, infiltrates the carbonaceous ceramsite and enters the micropores of the carbonaceous ceramsite for heavy metal fixation and three-dimensional network sealing, and natural cooling, that is, the finished three-dimensional network is solidified and sealed carbonaceous ceramsite; The impregnating material is polymer resin. The cured metal ions of the present invention are basically unable to dissolve and have high safety. At the same time, the carbonaceous ceramsite has certain hydrophobicity, strong weather resistance and toughness, and has high application value in light building materials, water resistance, heat insulation materials and the like.

The invention discloses a method used for improving cement raw material grindability and reducing TOC discharge with kitchen waste. According to the method, the kitchen waste collected from municipal solid waste is mixed with raw materials which are used for preparing cement raw material; and an obtained mixture is delivered into a flour mill for grinding, wherein the outlet of the flour mill is provided with a gamma-Metric analyzer used for real-time monitoring on chemical components of the discharged cement raw material. According to the method, kitchen waste is added into a raw material grinding system so as to improve grindability of the cement raw material, and reduce power consumption of the flour mill; ash obtained via combustion of the kitchen waste can be used for replacing clay raw material; TOC discharge of a cement production system is reduced at the same time; a large amount of organic substances with relatively heat value are obtained via drying of the kitchen waste, and are burnt in a preheater so as to generate heat energy, so that the temperature of waste gas is increased, and waste heat power generation is increased; the kitchen waste is subjected to low-temperature drying grinding, a large amount of residual heat energy obtained via cerement plant waste heat power generation is recycled, a kitchen waste dewatering problem is solved, and processing cost of the kitchen waste is reduced.

The invention discloses a method for preparing an aluminum electrolytic cell TiB2 cathode coating by adopting a plasma spraying technology. The method comprises the following steps: adding dried titanium boride powder, alumina powder and graphite powder in a high-temperature roasting furnace according to a certain ratio to form eutectic, crushing and ball-milling the eutectic, further performing ultrafine grinding on the eutectic, adding the ground the eutectic in a hopper of a plasma spraying device, starting a main control and mechanical arm of the spraying device, and controlling the distance between a nozzle and a substrate and the movement speed to form a TiB2 cathode coating composite on the surface of the aluminum electrolytic cell cathode carbon block. By adopting the method, the thickness of the TiB2 composite cathode coating in the industrial aluminum electrolytic cell can be effectively controlled, the industrial voltage of the aluminum electrolytic cell and the probability of secondary reactions can be reduced, the current efficiency can be effectively increased, the energy consumption can be reduced, the service life of the industrial aluminum electrolytic cell can be prolonged, the aluminum electrolysis production can be improved and the quality of aluminum products can be increased.
