The sludge composting fermentation device has the advantages that by adding biological strain and controlling the temperature, PH value and reaction time, the sludge, causing pollution to the environment, in a tap water plant is converted into fertilizer, the fertilizer effect of the sludge composting product can be enhanced, the heavy metal pollution risk of sludge composting can be reduced, and the equipment is reasonable in structure, low in cost and good in effect.

Description

A kind of sludge composting fermentation unit

Technical field

The utility model relates to mechanical equipment technical field, especially relates to a kind of sludge composting fermentation unit.

Background technology

Water factory refers generally to " water treatment plants ", utilize the aquatic product resident living water in the sources such as river, lake, underground water, industrial process waters and other waters of cities and towns as fire-fighting, afforest, water the water treatment plant of spilling road etc., carrying out in the process of purifying water process, tend to produce a large amount of mud, the mud that this factory produces every day is 1 ton of left and right; Similarly be sewage work, the amount of sludge producing when sewage purification is huger, general mud adopts the mode compost that is exposed to the sun, this method reaction is slow, weak effect, mud utilization ratio is low.

Utility model content

In order to solve, sludge composting reaction is slow, the low problem of utilization ratio, and the technical solution adopted in the utility model is as follows:

A kind of sludge composting fermentation unit, comprise computer controller, computer controller is connected with motor, motor is fixed on tank body side, and tank body top is hatch frame, and tank base is domes, in tank body, be provided with whipping appts, described tank body top arc side is provided with feeding device, and the tank body side that motor is housed is provided with biological inoculum opening for feed and aeration tube, and aeration tube extends to tank body opposite side; Described inner tank wall is equipped with temperature, PH inductor block; Described tank base both sides are respectively equipped with bleeder valve, and bleeder valve is connected with sieve apparatus.

Described aeration tube is arch, is evenly provided with aperture on aeration tube.

Described temperature, PH inductor block are evenly arranged in inner tank wall.

The height of described tank body is 80-160cm, and width is 2-3.6cm.

Described sieve apparatus can be sent to feeding device by material not up to standard, can realize cyclic production.

When work, mud is joined in tank body by feeding device, evenly spray and add thermophile bacteria by biological inoculum opening for feed, computer controller control driven by motor whipping appts stirs, aeration tube starts aeration simultaneously, after stirring, stop stirring and oxygen supply, now thermophile bacteria is as genus bacillus, the microorganisms such as thermophilic actinomycete start the easy degraded organic matter in digest and decompose mud, carry out fermentation reaction, release of heat, about about 24 hours, bacterial classification becomes logarithmic proliferation, first aerobic microbiological bacterium decomposes easy detritus, and draw a part of organic carbon/nitrogen nutrition composition, for zymophyte self-reproduction, nutritive ingredient is broken down into carbonic acid gas and water, emit heat and make to pile temperature rising.When temperature is during in 23-47 degree Celsius, mesophilic bacteria microorganism is more active; Along with heap temperature constantly raises, when temperature is during in 43-68 degree Celsius, high temperature microbe is as the dominate gradually such as thermophile bacteria, actinomycetes, mesophilic microorganism is suppressed even dead, organic matter decomposes faster, makes to pile temperature and rises to rapidly 58-70 degree Celsius or higher temperature, at this moment except perishable organic continuation decomposition, part Mierocrystalline cellulose and xylogen are also decomposed gradually, and soil ulmin starts to form.Facts have proved, compost temperature more than 58 degrees Celsius three days, just can kill parasitic ovum, pathogenic bacteria and weed seed in material, reaches the object of compost hazard-free, but compost temperature should not exceed 70 degrees Celsius simultaneously, otherwise will cause the dormancy of beneficial microorganism bacterium even dead, after this along with the decline of compost temperature, mesophilic microorganism bacterium starts again active, compost enters Secondary Fermentation, can be referred to as during this period of time the rear ageing stage, this organism that is conducive to more difficult decomposition all decomposes and becomes soil ulmin, the organism that amino acid etc. are more stable, fertilizer efficiency is improved greatly, after compost finishes, to ferment by sieve apparatus, material particles after decomposition fills bag, pile the fertilizer technology index completely qualified, respond well, contrast table is as follows:

Heavy metal content the key technical indexes contrast table

Organic fertilizer content the key technical indexes contrast table

Advantage of the present utility model: by adding biological inoculum, control temperature, pH value and reaction times, to environment be caused to the converting mud into fertilizer of mud, improve sludge composting product fertilizer efficiency, reduce sludge composting and produce heavy metal contamination risk, the fertilizer producing after compost can be used for turf greening, improvement alkaline land soil etc., and device structure is reasonable, cost is low, effective.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Embodiment

As shown in Figure 1, a kind of sludge composting fermentation unit, comprise computer controller 1, computer controller 1 is connected with motor 2, and motor 2 is fixed on tank body 3 sides, tank body 3 tops are hatch frame, tank body (3) bottom is domes, is provided with whipping appts 4 in tank body 3, and described tank body 3 top arc sides are provided with feeding device 5, tank body 3 sides that motor 2 is housed are provided with biological inoculum opening for feed 6 and aeration tube 7, and aeration tube 7 extends to tank body 3 opposite sides; Described tank body 3 inwalls are equipped with temperature, PH inductor block 8; Described tank body 3 two bottom sides are respectively equipped with bleeder valve 9, after bleeder valve 9 is opened, because tank body 3 bottom surfaces are domes, under action of gravity, material slides into the bleeder valve 9 of tank body 3 both sides, and bleeder valve 9 is connected with sieve apparatus 10, and sieve apparatus 10 is directly by material bagging.

Described aeration tube 7 is arch, is evenly provided with aperture 11 on aeration tube 7, thereby evenly accesses air.
