Description
Technical field
The present invention relates to Solid Waste Treatment, be specifically related to fully utilize a kind of environmental-protection fertilizing equipment of mud and the using method of applying sludge thereof.
Background technology
Along with the development of China's urban economy and the increase of population, the annual discharging of Sewage Plant dewatered sludge is about 550～6,000,000 tons, and is remarkable growth trend, has caused the serious environmental pollution.The in-depth of the raising of the popularizing of sewage treatment facility, treating capacity and degree of treatment has now strengthened the generation of mud, how reasonably to dispose municipal sludge, and solving its problem of outlet has become very urgent task.Municipal sludge composition more complicated, it contains abundant N, P and organic matter (being better than pig, cow dung), is good organic fertilizer resource, rationally utilizes on agricultural, to reducing pollution by chemical fertilizer, keep soil fertility, realizing that sustainable development plays an important role; But meanwhile, mud inevitably also contains some harmful components, as various pathogens, parasitic ovum, and heavy metal such as copper, aluminium, zinc, chromium, arsenic, mercury.China's south large tracts of land belongs to and lacks organic characteristic of acid red soil series, if suit measures to local conditions, in conjunction with the composition characteristic of mud, goes after profits and advoids disadvantages, and is rationally agricultural, will produce significantly society, economy and environmental benefit.
Summary of the invention
(1) technical problem that will solve
The purpose of this invention is to provide a kind of environmental-protection fertilizing equipment simple in structure, with low cost; The present invention also provides a kind of fertilizer efficiency feature that makes full use of mud, increases the output of plant, and don't can cause heavy metal pollution in the plant corpus, and the using method of the applying sludge that can improve the soil.
(2) technical scheme
In order to achieve the above object, the present invention takes following scheme:
It comprises cylinder, and this cylinder bottom is airtight, and the cylinder top is an opening, also has several apertures near near the cylinder bottom.
Wherein, described cylinder adopts the waste plastic bottle to make.
Wherein, described several apertures are 10-15.
In order to fully utilize mud, the present invention also adopts following method step:
1), with the fixative of flyash as heavy metal, mix by the flyash of 5-15 weight portion, the mud of 1000 weight portions; Or, mix by the potassium sulphate of 5-15 weight portion, the mud of 1000 weight portions with the fixative of potassium sulphate as heavy metal; Or, mix by weight the lime of 5-15 weight portion, the mud of 1000 weight portions with the fixative of lime as heavy metal;
2), mixed mud is put into fertilizer applicator, then fertilizer applicator is placed on the soil of plantation plant;
3), at the fertilizer applicator opening part, by artificial trickle and natural precipitation, make the nutriment in a fertilizer in the mud from fertilizer applicator, flow into soil, directly soil is applied fertilizer, heavy metal then is fixed in the fertilizer applicator and free from environmental pollution.
(3) beneficial effect
(1) because waste plastic bottle source is wide, to collect simplely, with low cost, fertilizer applicator is made simple, easily popularization.(2) with the fixing heavy metal of low-cost materials such as flyash, can improve the structure of mud, replenish the part nutrient element, reduce the transfer of heavy metal simultaneously to soil.(3) waste plastic, municipal sludge, flyash all belong to solid refuse, it are combined make full use of, and have increased soil fertility, have improved plant products, have realized the environmental objective that turns waste into wealth.
Description of drawings
Fig. 1 is the schematic diagram of environmental-protection fertilizing equipment of the present invention;
Fig. 2 is an environmental-protection fertilizing equipment of the present invention schematic diagram when using.
Among the figure: 1, fertilizer applicator; 2, mud; 3, soil; 4, basin; 5, aperture; 6, cylinder.
Embodiment
Following examples are used to illustrate the present invention, but are not used for limiting the scope of the invention.
As shown in Figure 1, the top of waste plastic bottle is removed, make cylindric, at even 10 of the apertures of cutter diameter 1cm of week of distance bottom 1cm, so that the nutrient in the mud 2 discharges.Quantitative fresh dewatered sludge (water content about 80%) is housed in the fertilizer applicator 1, and respectively with the heavy metal fixative: flyash, lime, potassium sulphate mix, and its proportioning is that every Kg dewatered sludge adds the 5-15g fixative.Then it vertically is placed on the soil 3 soil plantation plant.Its action principle is: mud 2 is stored in the fertilizer applicator 1, and nutrient flows into soil 3 by aperture 5, and heavy metal is fixed and be trapped in the fertilizer applicator, is convenient to collect and handles, in case cause secondary pollution.
Described mud derives from Guangzhou big Tan Sha sewage treatment plant; Flyash derives from Guangzhou Power Plant, and its composition comprises silicon, iron, calcium, manganese, phosphorus, carbon.
Below by the potted plant crop test of Guangzhou red earth technique effect of the present invention is described.
1) contrast 1: no mud;
2) contrast 2: mud is sneaked in the soil;
3) the mud fertilizer applicator of packing into;
4) mud+lime (every kg dewatered sludge adds 5g lime), the fertilizer applicator of packing into;
5) mud+potassium sulphate (every kg dewatered sludge adds the 10g potassium sulphate), the fertilizer applicator of packing into;
6) mud+flyash (every kg dewatered sludge adds 10g flyash), the fertilizer applicator of packing into.
With mud and red earth (dry weight ratio) is calculating in 1: 100, determines the mud consumption, and each handles 4 repetitions, determination of plant output and content of beary metal after the results.The result shows, flyash is compared with other processing with the processing that municipal sludge mixes with potassium sulphate, output height and content of beary metal lower (seeing Table 1).
