Ex-situ washing remediation method for nitrochlorobenzene-contaminated soil
InactiveCN102172614AThe process is easy to implementReduce labor inputContaminated soil reclamationEngineeringSlurry
The invention discloses an ex-situ washing remediation method for nitrochlorobenzene-contaminated soil, which comprises the following steps: crushing soil and sieving to remove stones and gravels; filling the soil into a washing reactor to fully mix the soil with a proper amount of washing solution, wherein the washing agent is ethanol; subjecting the washed mixture of slurry to two stages of sieving and filtering, wherein soil particles with large particle sizes are stopped by a screen; pumping the slurry mixture to soil-liquid separation equipment, recovering, filtering and purifying separated washing solution to regenerate the washing solution, regulating the concentration of the washing solution, and leaving the washing solution for washing at next time of washing. A sand filter column is used for filtering, active carbon is used for absorbing molecules of organic contaminants such as nitrochlorobenzene in the washing solution instead of molecules of ethanol serving as the washing agent, and thus, the washing solution is purified and can be recovered and recycling of resources is realized. The organic contaminant content of the washed soil reaches related standards. The soil particles which are sieved and filtered out can be used as building and road construction materials; and the soil particles obtained by solid-liquid separation can be used as raw materials for making concrete and fire bricks and also can be reclaimed. Thus, the whole soil remediation process is accomplished. In the invention, the process is easy to implement, small-scale industrial application can be realized, and an effective means is provided for scientific researchers for researching soil remediation.

The method comprises the following steps: fixing connection irons on inside wooden frameworks of wallboards at the sides of a window; fixing semi-I-shaped installing seats on a dividing wall of a car body, wherein the openings of the installing seats face to the window; inserting the outer sides of the wallboards at the sides of the window into the semi-I-shaped installing seats; fixing the connection irons with steel structures of the car body with bolts; fixedly connecting the window sides of the wallboards at the sides of the window with steel columns of the car body with connection boards; and after putting wallboards in the middle of the window in place, fixing the left and right sides of the wallboards in the middle of the window with the inside wooden frameworks of the wallboards at the sides of the window with wooden screws. The side wall realizes modularization, has a simple and compact structure and high efficiency and is convenient and fast to assemble. Under the condition of the same constructors, the constructors spend about 2 days on assembling the side wall of each car in a scattered manner, but the constructors only spend 2 hours on installing the modularly designed side wall of each car according to the method provided by the invention; therefore, the method has the following beneficial effects: the production efficiency is obviously improved; meanwhile, the installation quality and precision are higher; and the side wall is convenient to maintain and overhaul.

Production process of N-type back contact solar cell
InactiveCN102569518ARealize thermal diffusionReduce etchingFinal product manufactureSemiconductor devicesScreen printingSolar cell
The invention relates to a production process of an N-type back contact solar cell. The production process comprises the following steps of: flocking a silicon substrate so that a light reflective surface has a flock surface; oxidizing the silicon substrate; manufacturing a diffusion window on a back side of the silicon substrate; carrying out selective boron source thermal diffusion to enable the exposed silicon to be doped by boron to form a PN junction; removing an oxide layer and impurities; oxidizing the silicon substrate again; plating an anti-reflecting film on the light reflective surface of the silicon substrate; carrying out screen printing by using metal electrode paste; and sintering to obtain a metal electrode to finish the manufacturing of the cell. The production process disclosed by the invention is artful in concept, compatible with conventional industrial cell production and easy to realize industrial manufacturing; meanwhile, relative to the conventional solar cell, the N-type back contact solar cell manufactured by the production process disclosed by the invention has the advantages that: an etching step with higher cost is saved, and metal electrode screen printing is changed into a one-step screen printing from three-step metal electrode screen printing of the conventional solar cell. The production process disclosed by the invention is widely applied in the photovoltaic field and has favorable market prospect.
