Plant urease curing agent and application thereof in refuse landfill impermeable lining
The invention discloses a plant urease curing agent and application of the plant urease curing agent in an impermeable lining of a refuse landfill. The plant urease curing agent comprises plant urease, soluble calcium salt, urea, an adhesive and water. The mass ratio of the plant urease to the soluble calcium salt to the urea to the adhesive to the water is 10:5-10:5-30:1-2:200-400. A plant urease curing agent is mixed with clay according to the liquid-solid volume ratio of 110 L/m3, laid layer by layer and compacted on the bottom layer and the periphery of a refuse landfill to form an anti-seepage lining, the strength of the anti-seepage lining is improved by 1.75-2.53 times, the permeation heavy metal ions are reduced to 27-65%, the permeability coefficient is reduced to 1*10-7 or below, and thereby migration and permeation of the heavy metal ions are effectively reduced.
本发明公开了一种植物脲酶固化剂及其在垃圾填埋场防渗衬层中的应用，植物脲酶固化剂包括植物脲酶、可溶性钙盐、尿素、胶黏剂和水，所述植物脲酶：可溶性钙盐：尿素：胶黏剂：水的质量比为10：5~10：5~30：1~2：200~400。将植物脲酶固化剂按照1~10 L/m3的液固体积比与粘土拌和，逐层铺设并压实在垃圾填埋场的底层及四周即形成防渗衬层，使防渗衬层强度提高1.75~2.53倍，使透过重金属离子降至27~65%，渗透系数降低至1×10‑7以下，有效降低重金属离子的迁移和渗透。
