The invention belongs to the field of biochar adsorbing materials, and relates to a method for preparing modified biochar with aquatic plant waste and hematite. The method includes the following steps: (1) naturally drying aquatic plants prior to crushing to obtain aquatic plant powder; (2) crushing the hematite to obtain hematite powder; (3) weighing the hematite powder prior to putting the hematite powder into deionized water, and performing ultrasonic treatment to obtain suspension; (4) weighing the aquatic plant powder, soaking the aquatic plant powder in the suspension, and stirring and drying to obtain fully mixed aquatic plant and hematite mixture; (5) weighing the fully mixed aquatic plant and hematite mixture, putting the mixture in a batch-type atmosphere furnace, and feeding nitrogen into the furnace; performing temperature programming to the target temperature, and maintaining final-temperature pyrolysis; after the pyrolysis process is finished, obtaining the target product, namely the modified biochar. The modified biochar has strong adsorbability in nitrate and phosphate, high in stability and reusable.

The invention discloses an anti-corrosion treatment process for parts of a sampling machine. The anti-corrosion treatment process comprises the following steps that 1), impurity removal and rust removal are carried out on the surface of each part of the sampling machine; 2), sanding is carried out on the surface of each part which is subjected to the treatments in the step 1) of the sampling machine; 3), a sampling pipe of the sampling machine is soaked in rare-earth preservative which is subjected to a curing treatment, the rare-earth preservative is taken out after deposited on the surface of the sampling pipe, and then the rare-earth preservative is naturally air-dried at normal temperature; 4) the rare-earth preservative which is subjected to the curing treatment is sprayed on the surfaces of the other parts of the sampling machine; and 5), the sampling pipe which is subjected to the treatment in the step 3) is coated with an antioxygenic resin layer, and the other parts of the sampling machine are coated with the antioxygenic resin layer. According to the anti-corrosion treatment process, on one hand, the corrosion-resistant layer can be prevented from being impacted and rubbed and the anti-corrosion layer is firmly adhered to the surface of the sampling pipe, and on the other hand, the problem that the surface of the sampling pipe is corroded and damaged as oxygen and water in the atmosphere permeate and diffuse to the surface of the sampling pipe can be prevented.
