Abstract
The utility model discloses float-type spherical compound stuffing for a Tubificidae biological filter, which comprises a float. The upper end of the float is connected with an upper end face rack and a fixed hook; the lower end of the float is connected with a lower end face rack; a drop body is connected below the lower end face rack; a plurality of spherical combined stuffing units are arranged in the float; and bamboo-made filiform stuffing is filled in the spherical combined stuffing units. In the utility model, a spherical shell and a filiform bamboo-made substance filled structure are adopted by the stuffing, therefore, the float-type spherical compound stuffing has a big space channel, high strength, good mechanical property, small resistance, no blockage or deformation, durability and big specific surface area and is easy to wash; a bigger space is provided for the attached growth, the persistence and the metabolism of Tubificidae; bamboo-made substances are filled in the spherical shell, resist extrusion and cannot influence the growth and the breeding of the Tubificidae; the upper part of the float can be positioned by a support, thus, the inspection and the maintenance are convenient and the growth condition of the Tubificidae can be more conveniently monitored.
Description
Technical field
The utility model relates to the packing technique field, relates in particular to a kind of spherical compounded mix of Float cylinder type that is used for the Limnodrilus hoffmeisteri biological filter.
Background technology
Activated sludge process is the municipal wastewater treatment process that extensively adopt countries in the world, but can produce a large amount of excess sludges in operational process.Because the existence of heavy metals in excess sludge, pathogenic bacteria and organic micro-pollutants makes traditional soil utilize the way of mud more and more to be subjected to the scholar and the public's query.Therefore, burn the final selection that European countries such as often becoming Holland handle mud.Yet, because making, the moisture percentage in sewage sludge height has to concentrate before the sludge incineration and pre-treatment such as dehydration, moreover, small sewage treatment plant often need with concentrate, mud after the dehydration is transported to sludge incineration factory (or garbage burning factory) outward and does and centrally dispose, so, the comprehensive cost of sludge incineration generally all maintains high-order operation, and present stage also is difficult to obtain penetration and promotion.Estimation shows that excess sludge is handled, disposal costs is built up to entire sewage treatment plant usually and the 50%-60% of operation total expenses.Therefore, research and development low cost, exercisable mud decrement technology are continued saying it with interest for the various countries researchist always.
Mud decrement technology based on primary/metazoan predation microorganism has caused the extensive concern of Chinese scholars because of having advantages such as economical and efficient, non-secondary pollution.Limnodrilus hoffmeisteri is as the maximum metazoan that can observe in the Sewage treatment systems, can be attached to growth and breeding on the filler, have higher anti-pollution ability and bigger mud phagocytic activity, thereby be widely used in the research of mud decrement, and be considered to be used for a kind of comparatively ideal prey organisms of mud decrement.
The key of utilizing Limnodrilus hoffmeisteri predation microorganism to carry out mud decrement is that the assurance Limnodrilus hoffmeisteri can be stablized lasting growth and breeding in Sewage treatment systems; but the operational conditions of existing activated sludge process also not exclusively is fit to Limnodrilus hoffmeisteri; the growth of Limnodrilus hoffmeisteri certain fluctuation can occur usually; even mass mortality, finally cause the mud decrement DeGrain.For guaranteeing Limnodrilus hoffmeisteri growth and breeding in Sewage treatment systems stably, keep long and stable food chain, reach ideal mud decrement effect and efficient, be necessary to develop a kind of anti-water impact, help the new packing that Limnodrilus hoffmeisteri adheres to, grows, retains, breeds.
Summary of the invention
The utility model provides that a kind of mechanical property is good, maintenance is used for the spherical compounded mix of Float cylinder type of Limnodrilus hoffmeisteri biological filter easily, solved the problem that Limnodrilus hoffmeisteri can not stable growth, breeding in Sewage treatment systems.
A kind of spherical compounded mix of Float cylinder type that is used for the Limnodrilus hoffmeisteri biological filter comprises floating drum,
The upper end of described floating drum is connected with upper surface frame and stay hook, the lower end of floating drum is provided with the lower surface frame, frame below, described lower surface hangs a falling body, is provided with several spherical combined stuffing unit in the described floating drum, is filled with bamboo thread weighting material in the described spherical combination filler unit.
Described upper surface frame, lower surface frame and stay hook are made by iron material, and scribble preservative coat.
Described falling body is the steel weight, mainly plays fixed action, and its weight range specifically can be adjusted according to the floating drum size flexibly at 2～5kg.
Described upper surface frame, lower surface frame, stay hook, falling body guarantee stable being fixed in the Limnodrilus hoffmeisteri biological filter of floating drum energy, reduce the disturbance of water impact to sphere combination filler unit internal water earthworm.
Be provided with several spherical combined stuffing unit in the described floating drum.Described spherical combination filler unit shell is made of plastics, and diameter is 8～15cm, surface apertures 5～20mm.Be filled with bamboo thread weighting material in the described spherical combination filler unit, described bamboo thread weighting material diameter is 2～5mm, and described bamboo thread weighting material surface is done plucking and handled.
The advantage of the utility model filler is: the thread bamboo thing of filling in the spherical combined stuffing unit is easy to bio-film colonization, and can form the artificial environment that is similar to the Limnodrilus hoffmeisteri growth, the carry that is attached to that helps Limnodrilus hoffmeisteri, have following characteristics simultaneously: adopt spherical shell and thread bamboo thing interstitital texture, spatial channel is big, intensity is big, mechanical property is good, resistance is little, do not stop up, indeformable, durable, easy flushing, specific surface area are big, for the Limnodrilus hoffmeisteri apposition growth, retain with metabolism bigger space is provided; Thread bamboo thing is filled in the spherical material frame, is not afraid of extruding, can the growth and breeding of Limnodrilus hoffmeisteri not exerted an influence; Useable holder location in filler top is checked, easy to maintenance, is easier to the monitoring of Limnodrilus hoffmeisteri upgrowth situation.
