土壤先期固结压力的大小通常采用受周向约束柱状土样的快速单轴压缩测试方法获取,该值的确定不仅是土壤结构保护的基础参考,还为确定合理的作业机械轴重、农业机械的设计及其田间运用提供理论依据。该试验通过对江浦农场水稻土的实际测试,得到未受压实耕层土壤的先期固结压力范围为58.84～69.19kPa,而用拖拉机碾压处理后的先期固结压力区间上升为69.15～100.1kPa,表明拖拉机的碾压导致土壤先期固结压力的增加,即破坏了土壤的原始结构。目前的农业机械接地压力通常在70kPa以上,而大田所测的土壤先期固结压力却在60kPa左右,因此机械的使用必会造成土壤的压实及其结构的破坏。

With the application of resins in various fields, numerous waste resins that are difficult to treat have been produced. The industrial wastewater containing Cr(Ⅵ) has severely polluted soil and groundwater environments, thereby endangering human health. Therefore, in this paper, a novel functionalized mesoporous adsorbent PPR-Z was synthesized from waste amidoxime resin for adsorbing Cr(Ⅵ). The waste amidoxime resin was first modified with H3PO4 and ZnCl_(2), and subsequently, it was carbonized through slow thermal decomposition. The static adsorption of PPR-Z conforms to the pseudo-second-order kinetic model and Langmuir isotherm, indicating that the Cr(Ⅵ) adsorption by PPR-Z is mostly chemical adsorption and exhibits single-layer adsorption. The saturated adsorption capacity of the adsorbent for Cr(Ⅵ) could reach 255.86 mg/g. The adsorbent could effectively reduce Cr(Ⅵ) to Cr(Ⅲ) and decrease the toxicity of Cr(Ⅵ) during adsorption. PPR-Z exhibited Cr(Ⅵ) selectivity in electroplating wastewater. The main mechanisms involved in the Cr(Ⅵ) adsorption are the chemical reduction of Cr(Ⅵ) into Cr(Ⅲ) and electrostatic and coordination interactions. Preparation of PPR-Z not only solves the problem of waste resin treatment but also effectively controls Cr(Ⅵ) pollution and realizes the concept of “treating waste with waste”.
