The invention relates to the technical field of dyeing of textiles, in particular to a salt-free dyeing technology adopting ethyl alcohol. The dyeing technology is used for dyeing wool fabrics, the salt-free dyeing technology under the ethyl alcohol system is adopted, and a dye dissolution agent accounting for 5%-10% of a to-be-dyed fabric by weight is mixed with an ethyl alcohol solution accounting for 90%-95% of the to-be-dyed fabric by weight; the ethyl alcohol is taken as a dyeing carrier and used for dye conveying and energy transmission, the dye dissolution agent is used for dissolving dye, and the dissolved dye and the ethyl alcohol jointly form a dyeing solution; during dyeing, salt does not need to be added, ultraviolet radiation treatment is adopted, quick dyeing can be achieved,and 5% of water can be used as the dye dissolution agent. By means of the method, the application amount of the water and the salt can be significantly reduced, compared with a traditional technology, the application amount of water for dyeing is reduced by 90%-95%, the ethyl alcohol is recycled, and zero-discharge of dyeing is basically achieved; the dyeing time is shortened by 50%, the dyeing temperature is reduced by 10-20 DEG C, the energy is saved by 30% or above, and the sewage problem of the textile industry is solved by adopting the zero-discharge scheme.

The invention discloses a mine treatment system. The system comprises a greening rehabilitation system, a mine side slope rehabilitation device, distribution pipelines, a vegetation planting device, asewage treatment system and a total controller; the greening rehabilitation system comprises a side slope morphology generation module used for generating morphology information of a whole mine sideslope and setting a slope value of the side slope; the mine side slope rehabilitation device comprises a side slope rehabilitation mechanism used for rehabilitating the mine side slope according to aside slope rehabilitation drawing; the distribution pipelines comprise fixing fences and water spraying pipes which are arranged in the fixing fences and provided with rotatable spray-heads; the sewage treatment system comprises a sewage treatment device and a power device used for conveying treated sewage to the water spraying pipes used for vegetation irrigation. According to the system, by planting vegetation on the side slope, the side slope morphology is solidified, the probability of landslides is reduced, through vegetation, the side slope soil quality is improved, and meanwhile, secondary use of polluted water of a mine is achieved, wherein the polluted water of the mine is used for vegetation irrigation after water quality purification, and thus the purposes of polluted water treatment and irrigation water sources are achieved.

The invention discloses a flocculating agent for treating sewage in Chinese patent medicine production enterprises, wherein the flocculating agent comprises the following compositions: 30-45% of carapace crushed materials, 3-12% of modified chitosan, 0.05-0.5% of nanometer titanium dioxide, 0.1-0.5% of phytic acid, and 45-55% of zeolite; in order to optimize the effect, the flocculating agent is also added with 1-5% of white mica and 1-5% of active carbon. The flocculating agent provided by the invention is utilized to treat the sewage; the flocculating agent provided by the invention has very high efficiencies of removing COD (chemical oxygen demand) and BOD (biochemical oxygen demand); and the flocculating agent provided by the invention is efficient and economical.

The invention provides a water heater. The water heater comprises a filter unit, a dirt collecting pipe and a flow path control device, wherein the filter unit is provided with a filter element, a water inlet hole, a clear water outlet hole and a sewage outlet hole; the dirt collecting pipe is configured for receiving water from a blow-off pipe and the dirt collecting pipe; and the flow path control device is configured for opening or closing a water route between the inlet of the blow-off pipe and the outlet of the dirt collecting pipe and a water route between the sewage outlet and the outlet of the dirt collecting pipe at the same time in a controlled way. The water heater provided by the invention has the advantages that the water route between the inlet of the blow-off pipe and the outlet of the dirt collecting pipe and the water route between the sewage outlet and the outlet of the dirt collecting pipe are opened at the same time when a filter screen and / or the dirt in a water tank need to be cleaned, and the filter element in the filter unit does not need to be disassembled, so that cleaning is simple and convenient, the problems of manual disassembly and cleaning of the filter element and pollution discharge difficulty are solved, cleaning period of the water heater is shortened, maintenance cost is saved, and water quality and usability of the water heater are improved.

The concentrated draining anti-freezing train toilet is developed on the basis of available washroom and toilet. It has concentrated draining pipe installed inside floor and the concentrated draining pipe is connected to the drain pipe and floor drain of both washroom and toilet and has outlet connected to toilet and is provided with electrothermal belt and heat insulating material. The sewage from both washroom and toilet is drained from toilet and there is temporary sewage storing apparatus at the outlet of the concentrated draining pipe, so that the present invention solves the problem of contaminating train chassis. Owing to the electrothermal belt and heat insulating material, the present invention avoids the freezing and jamming of the draining pipe. The present invention may be used to replace available train toilet.

The invention relates to a method for removing impurity of mother liquid in a preparation process of calcium carbonate crystal whisker, comprising the following steps of: (1) adding a barium chloride solid into the mother liquid in the preparation process of calcium carbonate crystal whisker; stirring the mixture to react for 0.5-2h at the normal temperature; and filtering in vacuum to obtain themother liquid subjected to the removal of sulfate radical; (2) adding a calcium removing agent in the mother liquid subjected to the removal of the sulfate radical; introducing CO2, stirring the mixture to react until a pH value of the mother liquid is 7; stopping aeration, and filtering in vacuum to obtain the mother liquid subjected to the removal of calcium; and (3) adding a flocculating agentwith mass concentration of 5 thousandth; stirring, standing and precipitating the mixture; and filtering in vacuum to remove the impurity. The invention has the advantages of simple operation and high impurity removal efficiency.
