The disclosure provides a structure for treating saline alkali soil and a biological treatment method, relating to the technical field of bioremediation for special soil and solving problems of single existing saline alkali soil improvement method, long improvement period, high cost and poor effect due to a single material. In the disclosure, a collecting layer, impermeable layers, and a plough layer are paved upward from a saline alkali soil layer in sequence. The impermeable layers and the collecting layer are made with a biological material, and the plough layer is improved, which reduces the content of harmful salt in the plough layer and improves the water holding capacity and permeability of soil in the plough layer. A collecting pipe network is buried under the plough layer, and collection pools are arranged at points of the pipe network for salt collection, permanently removing harmful salt components in the saline alkali soil.
The present invention discloses a disposable multi-stage cigarette holder filter apparatus, relates to the technical field of production of filter cigarette holders, and solves the problems of high cost, complex preparation process and poor filter effect of existing disposable filter cigarette holders. A composite filter rod, a filter layer, a cooling layer, a smoke dispersing layer, a cigarette holder connector and a cigarette body are sequentially connected from bottom to top into a cylinder structure; an outer packaging paper is arranged outside the cylinder structure; a plurality of air inlets are formed in a surface of the outer packaging paper corresponding to the smoke dispersing layer; and a filter capsule is arranged in the filter layer. The disposable multi-stage cigarette holder filter apparatus reduces the harm of tar and nicotine to smokers by introduction of air and multi-stage filtration, which uses mainly biomass materials wide in source as raw materials.
The present invention relates to the technical field of special soil bioremediation, and disclosed are a structure for saline-alkali soil treatment and a biological treatment method, solving the problem that the existing saline-alkali soil improvement method is single and has long improvement period, high cost and poor single-material effect. In the present invention, a collection layer, an anti-seepage layer, and a tillage layer are sequentially laid upwards from a saline-alkali soil layer; the anti-seepage layer and the collection layer are manufactured using biological materials, the tillage layer is improved, and a comprehensive treatment method comprising improvement of the upper tillage layer, seepage prevention of the lower portion, and collection of salt in the upper tillage layer and the lower saline-alkali soil layer is used, thus effectively reducing the content of harmful salt in the tillage layer, and improving the water holding capacity and air permeability of soil in the tillage layer. Moreover, a collection pipe network is buried below the tillage layer, and a collection pool is arranged at each pipe network node to collect salt, achieving resource utilization, and achieving the effect of permanently removing harmful salt components in saline-alkali soil.
Disclosed are a constructed wetland structure and methods for preparing and using a carbon source, which relate to the technical field of biological treatment of water pollutants, and solve the problems of poor uniformity, complexity, unsatisfactory effects and high operating costs in existing carbon source adding methods. The present disclosure includes a water inlet pond, a treatment unit, and a water storage pond, which communicate in sequence. In the treatment unit, plant straws and biochar are used to prepare a carbon source. By modifying the carbon source material, the carbon source is released stably. By arranging carbon source layers, under the action of a water flow, the uniformity of carbon source distribution is guaranteed. The carbon source is periodically cleaned and replaced. Carbon source material is a biomass material which features a wide source and low costs.
