Abstract
The utility model relates to a reinforced volcanic filter material for a sewage treatment biofilter. The reinforced volcanic filter material is characterized in that: a ball made of volcanic is taken as an inner core material; a hollow ball made of one of flyash, cement, expanded perlite, pumice stone and sepiolite is taken as an outer coating material; the outer coating material is provided with dense micropores; and the outer coating material and the inner core material are tightly combined. The reinforced volcanic filter material is suitable to serve as a filter material for the sewage treatment biofilter, and has the advantages of low production cost, good operating effect, no toxicity or harm, and long service life.
Description
Technical field
The utility model relates to a kind of subsidiary material of WWT, specifically is a kind of filtrate that is used for the biological filter of WWT, utilizes this filtrate to carry out the sewage treating efficiency height, and is effective.
Technical background
Filtrate is the main and important component part of BAF; BAF has that effluent quality is good, hydraulic detention time is short, floor space is little, investment and working cost is low, capacity of resisting impact load strong and advantage such as convenient management; Be a kind of environmental protection, economy, efficient, energy-conservation WWT new technology; Renewable and the sustainable utilization of water resources be can realize, shortage of water resources, insufficient funds, the technological present situation that falls behind relatively that the wastewater treatment in China field is faced are very suitable for.Filtrate as biofilm carrier is the key element of BAF last effect, filter structure to microbial growth, important influence comes off.In China, BAF is in the popularization stage, and the research of filtrate will be the BAF key of widespread adoption at home.Therefore it is high to need to propose operational efficiency, the filtrate of effective biological tank.
The utility model content
The purpose of the utility model is in order to solve the problems of the technologies described above, to propose a kind of WWT biological filter with enhancement type volcanics filtrate, and this filtrate production cost is low, last effect good, nontoxic, long service life.
The purpose of the utility model realizes through following technical scheme: the WWT biological filter is with enhancement type volcanics filtrate; It is characterized in that: the spheroid of processing with volcanics is the internal layer core material; The hollow ball of processing with material one of in flyash, cement, pearlstone, float stone, the sepiolite is outer dress material; This skin dress material is provided with dense micropore, and outer dress material and internal layer core material are closely linked.
The ceramic grain filter that the utility model uses has overcome some defectives of domestic currently available products, and the filtrate of higher specific surface area and bigger voidage is arranged.Wrap outer dress material in volcanics spheroid outside, made full use of the advantage of volcanics, can save material again, strengthen the intensity of filtrate, improve the work-ing life of filtrate with the collection micropore of stopping navigation.
Utilize the filtrate of the utility model to have good last effect: the denitrification filter pool starting period is shorter, can get into the denitrification filter pool steady operation period very soon; Use the denitrification filter pool of this filtrate, after the back flushing decubation shorter, production cost is low, last effect good, nontoxic, long service life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The profile of the utility model product does not receive the restriction of this figure, and only profile changes the protection domain that also belongs to the utility model.
Embodiment
The utility model is the explanation of into going up the step: embodiment: below in conjunction with accompanying drawing and embodiment referring to accompanying drawing; The WWT biological filter is with enhancement type volcanics filtrate; The spheroid of processing with volcanics is an internal layer core material 2; The hollow ball of processing with pearlstone is outer dress material 1, and this skin dress material is provided with dense micropore, and outer dress material and internal layer core material are closely linked.
It below only is the embodiment of this patent; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of this patent.
