Abstract
Feces and impure washing water are discharged in a diffluentence mode, and devices and technologies for processing impure washing water are simplified. The feces are collected through a vacuum water saving toilet, enters a collection tank through a vacuum pipe, and is directly mixed with domestic waste after being separated and crushed. The feces and the domestic waste are prepared into farmyard manure. The whole set of technologies are favorable for large scale automatic production, and can save a large number of machines and transportation devices. The vacuum water saving toilet has the advantages of greatly water saving, good odour control, favorable cleaning effect, less pipeline excavation quantity, economical pipe material dosage and reliable performance. The method can be used for ecological tourism regions, anew constructed city subzones and water deficient areas, and is favorable for environmental protection, resource regeneration and sustainable development.
Description
The invention belongs to the manufacture method of organic composite fertilizer, particularly make the method for compound manure with ight soil and domestic refuse.
Current, the sanitary sewage in city and domestic refuse are to cause the important factor of city environmental pollution.Sanitary sewage comprises ight soil and assorted wash water, the interflow enters sewer line, through septic tank the excrement slag is precipitated again, the sanitary sewage overwhelming majority is the discharging rivers and lakes directly, handle without Sewage Plant, because the investment of construction sewage work is too big, working cost is high, the Sewage Plant surrounding enviroment are abominable, and the Sewage Plant after building up is also seldom used.Therefore, sanitary sewage is the main source (accounting for more than 50%) of China's water pollution, is higher than the pollution of trade effluent.Domestic waste is if adopt the burning mode to handle, and invests hugely, and working cost is high, and is easy to generate Dioxins and causes secondary pollution; Landfill waste then need take a large amount of valuable soils, also has the secondary pollution problem.At present, developed both at home and abroad the technology that domestic refuse is made compost, the copropel that extracts in the rubbish after sorting, the fragmentation and the septic tank or the mud of Sewage Plant have been mixed the production compost; Vacuum closet and system have been used in external existing minute quantity area, have produced vacuum closet and parts in batches as U.S. AIRVAC company, form transnational company.But assorted wash water is also collected except collecting ight soil by this vacuum closet and system, and the blended sanitary sewage is delivered to vacuum station, is pumped into sewage work again, discharging again after focusing on.This technology has increased the quantity and the difficulty of sewage disposal, the investment that has increased Sewage Plant with the processing that mixes of ight soil and assorted wash water.From sewage work, get mud or from septic tank, get copropel, need a large amount of mechanical means and transportation equipment, dejecta moisture reaches 99%, also need through natural mummification, regulate water ratio ability and domestic garbage mixing, and also be mingled with some heavy metals and objectionable impurities in mud or the copropel, should not be used to do fertilizer.
The present invention aims to provide a kind of environment protection method of making compound manure with ight soil and domestic refuse; be that ight soil is collected through vacuum closet system; and the wash water emission treatment separately of mixing; ight soil through the vacuum pipe network directly and the domestic garbage mixing after the sorting fragmentation carry out compost; its objective is sanitary sewage disposal is greatly simplified; can make full use of ight soil and domestic refuse again and make compoiste fertilizer, turn waste into wealth.This fertilize preparation craft can be saved a large amount of mechanical means and transportation equipment.For contaminated solution, raising eco-environmental quality provide a kind of simple scheme.
The present invention the steps include: with the environment protection method of ight soil and domestic refuse manufacturing compound manure
(1) ight soil is collected by the vacuum water-saving toilet, enters holding tank in the vacuum station by the vacuum pipe network;
(2) domestic refuse is through sorting, and wherein perishable organism mixes with the ight soil of holding tank in (1) through fragmentation;
(3) (2) resulting mixture is inserted organic ferment, send into an in-vessel composting system and carry out compost;
(4) gas that in-vessel composting system is produced pumps to the secondary in-vessel composting system, simultaneously, the product of an in-vessel composting system is transported to two secondary in-vessel composting systems compost again, finally makes finished product fertilizers.
In the aforesaid method, perishable organism can be broken into particle or the fragment of diameter 30～50mm in the described domestic refuse, and the described in-vessel composting system compost time can be 5～10 days, and the compost time can be 20～30 days to described secondary in-vessel composting system again.
In the aforesaid method, a described in-vessel composting system can be the revolving cylinder storehouse, and described secondary in-vessel composting system can be vertical layering tower silo, the product of an in-vessel composting system is transported to the secondary in-vessel composting system can adopts closed worm conveyor.
Utilize method provided by the present invention to make organic composite fertilizer, ight soil and the shunting of assorted wash water are handled, assorted wash water is handled simple, the dejecta moisture that the vacuum water-saving toilet is collected is about 80%, the composting material water ratio that mixes the back acquisition with organic waste is 45%～50%, just in time meets the water ratio of compost needs, need not add or concentrated moisture, a whole set of technology helps mass automatic production, can save a large amount of mechanical means and transportation equipment.Simultaneously, vacuum water-saving toilet system conserves water 80%～90% than traditional gravity water flushed toilet, and ozone Control is good, and clean effective, the blow-off line size is little, and the pipe canal digging amount is little, tubing consumption economy, dependable performance.This method is applicable to Ecotourism district, newly-built urban life sub-district and water-deficient area, meets the spirit of protection environment, resource recovery, Sustainable development.
Fig. 1 is a technological process block diagram of the present invention
At present, HUST succeeds in developing vacuum closet and system, and each auxiliary bath only needs about 1 liter.The biotope at 200 families, each household be by 4 people, totally 800 people, and the ight soil output is 0.5 kg/day per capita, about 1.6 tons of the gross weight of ight soil and water.According to Wuhan City's statistical information, the domestic refuse quantity discharged is about 1 kilogram/man day per capita, so this sub-district domestic refuse quantity discharged is 800 kg/day, wherein perishable organism accounts for 50%, it is 400 kilograms, so ight soil and rubbish mixing gross weight every day are 2 tons, perishable organism after the fragmentation is mixed in mixing machine with ight soil, part by weight by 10% in the mixing process adds natural organic ferment, compound residence time of an in-vessel composting system by 5 days, compound was totally 10 tons on 5th, adopted 2 revolving cylinder storehouses, and every storehouse combined amount is 5 tons, the diameter in revolving cylinder storehouse and length are than D: L=1: 7～9, filling degree 70～80%, therefore optional its diameter is 1 meter, length is 8.5 meters.The compost time length is 20～30 in the secondary in-vessel composting system, utilizes 55～65 ℃ of the temperature of a compost, makes perishable organism continue to decompose, and finally makes finished product fertilizers.The secondary in-vessel composting system adopts vertical layering tower silo, and in 30 days, tower silo diameter D was 3.8 meters, and height H is 4 meters, and volume is about 68m
3, storehouse top feeding, storehouse bottom discharge.The exhausting amount of supporting blower fan is 2.4m
3/ hour, the gas of an in-vessel composting system generation is pumped to the bottom of secondary in-vessel composting system, absorbed by grog.Adopt closed worm conveyor that the product of an in-vessel composting system is transported to the secondary in-vessel composting system, can effectively prevent distributing of stink and heat.
