The invention discloses a composition capable of promoting hair growth and blackening of white hair and application of the composition. The composition comprises an active component, a composite additive and water, the active components comprise an ammonium acryloyldimethyl taurate / beheneth-25 methacrylate cross-linked polymer, fullerene, cyclodextrin, betaine, tocopheryl acetate and sodium hyaluronate. The composition which can be combined with minoxidil can play a role in synergistically enhancing the hair growth effect; the fullerene composition can repair the activity of damaged hair follicle cells, maintain the normal function of hair follicles, reconstruct microcirculation and repair scalp barriers; minoxidil can expand blood vessels and promote nutrition delivery; the combination of fullerene and fullerene can enhance the transdermal absorption of fullerene, accelerate the effect of fullerene, and accelerate and promote hair growth. Meanwhile, the side effects such as dermatitis, rash or skin irritation of minoxidil on scalp are reduced.

The invention belongs to the technical field of waste gas treatment, and particularly relates to a waste gas treatment device for a laboratory fume cupboard, which comprises a base, an air inlet hollow plate arranged above the base, an adsorption filtering unit arranged on one side of the air inlet hollow plate, an air inlet pipe, an air outlet pipe, an air outlet pipe, a gas outlet pipe and a gas outlet pipe, the air inlet pipe is fixedly inserted into the end face of the air inlet hollow plate, and the air inlet pipe communicates with the air outlet end of a ventilation system of the ventilation cabinet. Harmful waste gas and harmless air can be discharged separately, consumption of adsorption filler is reduced, the waste gas treatment load is reduced, the regeneration time of the adsorption filler is prolonged, the use convenience is improved, secondly, the waste gas detection accuracy can be improved through the mode of compressed exhaust and standing waste gas detection, and the waste gas treatment efficiency is improved. Water vapor and part of organic solvent volatile gas in the waste gas can be condensed into liquid to be separated, and meanwhile, personnel can be reminded to replace or regenerate the adsorption filler in time.

The present application relates to a kind of renewable hydrogen sulfide removing agent and its preparation method and application, the renewable hydrogen sulfide removing agent with silica alumina gel as carrier, by loading aluminium hydroxide colloidal solution to silica alumina gel carrier, continue water vapor aging makes aluminium gel and carrier secondary combination, thereby obtains the hydrogen sulfide removing agent with more concentrated pore size distribution, active adsorption site is more abundant.The removing agent is suitable for the removal of hydrogen sulfide in hydrocarbon organic medium, the use condition range is that hydrogen sulfide concentration is less than 1000ppm, removal precision is less than 0.1ppm.When saturated with hydrogen sulfide, the scavenger can be regenerated under the purge of oxygen-free atmosphere, restore removal capacity, regeneration temperature is 250~300 ℃.Compared with prior art, the hydrogen sulfide removing agent prepared in the present application has more prominent hydrogen sulfide removal capacity, adsorption capacity is increased by 3-5 times, and regeneration cycle is prolonged by 2-5 times.

The application discloses an intelligent treatment system and method for electroplating chromium-containing wastewater, which comprises a sensor module, an image acquisition module, an intelligent control center and a controlled module; the sensor module is used for collecting operation data; the operation data comprises pH data and ORP data; the image acquisition module is used for collecting supernatant image data of a sedimentation tank; the controlled module is used for carrying out frequency conversion control of a dosing pump when adding chemicals to a chromium-breaking tank and / or when adding acid or alkali to a pH adjusting tank; and the intelligent control center is used for analyzing the received operation data and image data, and sending control signals to the controlled module to realize frequency conversion control of the controlled module. The application can accurately control the amount of reducing agent, thereby saving the amount of reducing agent and reducing the subsequent treatment load.
