Description
Technical field
The utility model is a kind of vehicle-mounted removable soil washing prosthetic appliance, with powertrain system, soil pulverizing washing system and medicament loading system for core, mainly through physico-chemical process, the soil after pollution is repaired, belong to the harmless treatment of soil discarded object and recycling field.
Background technology
Along with the increase of industry, the aggravation of municipal pollution and agrochemicals kind, quantity, heavy metal pollution of soil is day by day serious, and pollution level is aggravated, and area expands year by year.Because heavy metal contaminants poor mobility, holdup time in soil are long, can not be degraded by microorganisms, and finally can affect human health through the medium such as water, plant.Therefore, heavy metal pollution of soil problem has become the important content of current Research of Environmental Sciences.
Current China regional agriculture environment corruptions is very serious.According to statistics, China's industrial triwaste pollution cultivated area 266.7 ten thousand hectares in 2000, is increased to 666.7 ten thousand hectares for 2010, within 2014, is increased to 1,000 ten thousand hectares.At present, the whole nation suffers the cultivated area polluted in various degree close to 2,000 ten thousand hectares, accounts for 1/5 of cultivated area.The grain drop in production that China causes because of heavy metal pollution is every year more than 1,000 ten thousand tons, and contaminated by heavy metals grain reaches 1,200 ten thousand tons, adds up to economic loss at least 200 hundred million yuan.According to the investigation in recent years of Ministry of Agriculture's environmental monitoring system, in 320 emphasis contaminated areas in the very fast area of the economic developments such as China 24 province (city) outskirts of a town, sewage irrigation district, industrial and minerals, polluting the land for growing field crops crop acreage exceeded standard is 60.6 ten thousand hectares, accounts for 20% of the investigation gross area.The crop acreage that wherein content of beary metal exceeds standard accounts for pollutant and to exceed standard more than 80% of crop acreage, and especially Pb, Cd, Hg, Cu and combined pollution thereof are the most outstanding.
The suburbs, current China most cities soil all receives pollution in various degree, and wherein Cd pollutes comparatively general, and secondly nearly 1,000 ten thousand hectares of contaminated area is Pb, Zn, Cu, Hg etc.The content of beary metal such as Cd, Cr, As, Pb in the foods such as much local grain, veterinary antibiotics is had to exceed standard and close to critical value.Wherein most irrigation due to trade effluent is caused.Irrigating region as old in Suburb of Guangzhou, in soil, the content of Cd is up to 228mg/kg, and average content is 6.68mg/kg, and Zhang Shi irrigated area, Shenyang has 2533 hectare of land to suffer the pollution of Cd, wherein severe contamination account for 13%.
The migration of heavy metal in soil-botanical system directly has influence on growth and development of plants, thus affects the seed output and quality of crop.Heavy metal is the toxic element of harm plant growth, if content of beary metal is too high in soil, can destroy the chlorophyll structure of plant leaf blade, reduces the absorption of root system to moisture and nutrient, suppresses root growth, cause plant physiology obstacle and reduce output.Research shows, heavy metal pollution is very large on the impact of soil urease liveness, and with the increase of heavy metal-polluted soil concentration, urease activity downward trend is obvious, and as in pot marigold, urease activity fall is 51 ~ 88%; In Chinese rose, urease activity fall is 36 ~ 78%, therefore can represent with soil urease liveness change the degree that soil beatification pollutes.
In order to improve agricultural tillage land used ecological environment of soil, Appropriate application land resource, be badly in need of carrying out repair process to contaminated soil, and a kind of effective equipment is provided, realize fast and effeciently processing contaminated soil.In prior art, a kind of Novel soil elution machine (201120112397.5) of Chinese patent, described Soil leaching machine, it adopts spray system, soil is mixed with reparation solvent, the soil after pollution can be processed thus reach the object of pollution abatement, but this utility model exists following not enough: (1) the utility model adopts spray process cannot ensure soil completely and repair fully mixing of solvent, and the heavy metal waste material produced cannot guarantee effectively to be separated with soil; (2) this utility model adopts trailer-type mobile platform, needs towing vehicle extraly, therefore implement not convenient time mobile.
A kind of soil improvement elution device (201420460584.6) of Chinese patent, pending soil is sequentially passed through drip washing pond, contaminated soil layer and collecting tank by this utility model, realizes the reparation of soil.This utility model exists following not enough: (1) whole system floor space is large, exists, easily cause the secondary pollution to surrounding enviroment to dig the form of building foundation ditch on ground; (2) this utility model does not possess locomotive function, cannot realize the continuation process of other being polluted to plot; (3) this utility model is hand-guided, cannot realize automation mechanized operation.
A kind of Portable heavy metal contaminated soil elution device (201420192592.7) of Chinese patent, heavy-metal contaminated soil is sequentially passed through leacheate accumulator tank and the process of reactor realization to contaminated soil by this utility model, simultaneously by vacuum absorber, waste liquid accumulator tank, the process of devil liquor recovery processor realization to waste liquid.This utility model exists following not enough: (1) system adopts multilayer up-down structure, and its reactor is in a high position for system, and this utility model does not have contaminated soil filling equipment, is difficult to realize effectively processing it; (2) often pending contaminated site is large in number and widely distributed, and this utility model, without mobile platform, realizes portable process heavy-metal contaminated soil difficulty very large.
Chinese patent moveable-type soil drip washing apparatus and method (201210126353.7) thereof, this utility model patent adopts wet type sieve to be sieved by contaminated soil, the drip washing treatment tank adding provisional civil engineering processes, and realizes the repair to soil.This utility model patent exists following not enough: the drip washing treatment tank of (1) provisional civil engineering can not be called moveable-type soil drip washing apparatus, its comparatively simple civil engineering foundation pit cannot realize mobile and secondary use, easily produces secondary pollution to surrounding enviroment simultaneously; (2) how equipment is transported to next procedure to the soil after the filling mechanism of pending soil and wet screening and does not mention.
