The invention relates to an elastic fiber fabric, in particular to an elastic fiber fabric and a preparation method thereof. Warps and wefts are respectively 150D or75D PTS elastic yarns. The elastic fiber fabric is prepared through the steps of winding, twisting, sectional warping, healding, weaving, blank inspection, unrolling and flattening, pre-shrinking treatment, presetting, dyeing, reduction clearing and finishing. The elastic fiber fabric and a preparation method thereof have the advantages as follows: the structure is simple, the chemical fiber differentiation is promoted, the added value is increased, the preparation steps are scientific and reasonable and conform to the basic state policy of energy conservation and emission reduction, and the fabric feels like nylon, has a bright and pure color, is far lower than spandex in price and is a preferred garment material.

The invention provides a processing method of high-concentration industrial phenolic wastewater. According to the processing method of the high-concentration industrial phenolic wastewater, an efficient extracting agent and the phenolic wastewater are fed into an extracting tower to be mixed at a certain ratio, and then the high-purity phenolic wastewater is extracted and pre-processed at a certain temperature through a reverse liquid-liquid contact. The wastewater processed by the processing method provided by the invention can meet the requirement of various water quality indexes of biochemical treatment; the problem due to process current high-concentration phenolic amino wastewater produced via chemical enterprise is solved; the crude phenol and stronger ammonia water which are in a certain economic value can be recovered; and the optimal win-win combination of environment-friendly performance and economic benefit is achieved. The processing method provided by the invention is simple in technical process, continuous, and low in energy consumption; the extracting agent can be recycled; the scale production can be completely achieved; the basic state policy of integral sustainable development on resource, energy and environment is really demonstrated; and good circulation of three benefits is achieved, which means the harmony and unity on society, economy and environment.

The invention discloses a walling, which comprises hollow inner walling and a vacuum package layer, wherein, the vacuum package layer is positioned on the surface of the hollow inner walling. By utilization of the principle that vacuum is heat insulated and soundproof, the walling has good heat insulation and sound insulation effects. The walling has a simple structure and does not need to adopt an insulating layer which is made of special heat-insulating materials; and due to removal of the heat-insulating materials, the walling can reduce the production cost and meet the demand of the priorbasic state policy of building energy conservation, and is favorable for all-round promotion and application. The invention also discloses a walling construction method, wherein, the vacuum package layer is embedded into the surface of the hollow inner walling. The walling construction method has the construction difficulty which is far smaller than that of the prior insulated walling, can effectively save the building cost, and brings more economic benefit for users.
