The invention discloses activated carbon capable of deeply purifying drinking water and a preparation method for the activated carbon. The method comprises the following steps of: (1) mixing crushed and ground weakly caking coal and an additive to obtain a mixture, and performing briquetting molding on the mixture to obtain a briquetted material, wherein the additive is selected from at least two of NaOH, KOH, NaNO3, KNO3 and KCl; (2) carbonizing the briquetted material to obtain a carbonized product; and (3) activating the carbonized product to obtain the activated carbon. The activated carbon provided by the invention has a special function of deeply purifying the drinking water, so that blanks in China are filled, and a new product is added to functional type activated carbon products; and the preparation method provided by the invention is simple, has industrial operability, belongs to low-cost and high-performance products and has higher economic value and a better social significance.

The invention discloses a small-scale river channel simple purification treatment device, comprising a main body symmetrically arranged on the left and right, a rotating drum is arranged between the main bodies, the left and right ends of the rotating drum penetrate through and are rotatably connected to the main body. There are channels running through the left and right sides. The outer circular end face of the rotating drum is arranged in an annular array and fixed with four mud guide plates. The mud guide plates are provided with a telescopic cavity with an opening away from the symmetrical center. The telescopic cavity can slide. There is a telescopic plate, one end of the telescopic plate away from the symmetrical center is fixed with a moldboard, the annular inner wall of the channel is annularly arrayed and connected with four mud inlets that open outward; the present invention adjusts the telescopic situation of the telescopic plate , which can make the device walk directly on the flat road, avoiding the trouble of using vehicles to carry, and at the same time, it can be adjusted according to the depth of the river channel during work, which can meet the purification needs of more river channels and is more convenient to use.

The invention discloses an indoor air purifier. The indoor air purifier comprises a main case, a filter unit, a draught fan and an air exhaust device, wherein the filter unit and the draught fan are arranged in the main case, and the air exhaust device is arranged above the top of the main case. The top and the bottom of the main case are provided with openings. The two sides of the bottom of the main case are respectively provided with a support, so that the main case is suspended, and the opening in the bottom of the main case serves as an air inlet. The draught fan comprises a driving motor with two output shafts, wherein the driving motor is fixed into the main case, and the two output shafts of the driving motor are respectively connected with a wind wheel; a volute is arranged on the periphery of each wind wheel, and the upper end of each volute is communicated with the air exhaust device. Air can enter the bottom of the indoor air purifier at 360 degrees so that the requirement for large-area air purification can be met; air flow absorbed from the bottom can be exhausted from four sides of the top through the wind wheels on the two sides at the same time, and strong negative pressure is formed in an air flue, so more air can be absorbed in from the air inlet in the bottom, the adsorption capacity of the air inlet can be increased, more air can be filtered in a short time, the circulation speed of the air in a room can be increased to the maximum extent, and the efficient purifying effect can be achieved.
