Abstract
The utility model provides a combined type reactor for synchronous wastewater and sludge degradation with tubificidae. The combined type reactor comprises a reactor body provided with an oxygen-poor zone, an anaerobic zone, an aerobic zone and a sedimentation zone, wherein a first separation plate, a second separation plate and a third separation plate are arranged among the zones in sequence; circulating holes are formed in the lower part of the first separation plate, the middle part of the second separation plate and the upper part of the third separation plate; a baffle plate is further arranged on the right side of the third separation plate; a micro-pore aerator is arranged at the bottom in the aerobic zone; a spherical filler and an aeration device are suspended on the upper part in the aerobic zone; a plurality of layers of plate-shaped fillers are arranged below the spherical filler; the spherical filler and the plate-shaped fillers are inoculated with the tubificidae; a sewage reflowing outlet is formed in the bottom of the sedimentation zone. According to the combined type reactor for the synchronous wastewater and sludge degradation with the tubificidae, wastewater and sludge can be degraded effectively and synchronously in a wastewater treatment system so as to realize the effects of synchronously and stably carrying out wastewater treatment and sludge reduction and greatly save the capital cost of a wastewater treatment plant and the sludge disposal cost.
Description
Technical field
The utility model relates to environmental protection equipment field, is specially the synchronous Limnodrilus hoffmeisteri degraded of a kind of wastewater sludge combined reactor.
Background technology
Activated sludge process is the municipal wastewater treatment process that countries in the world extensively adopt, but can produce a large amount of excess sludges in operational process.Due to the existence of heavy metals in excess sludge, pathogenic bacteria and organic micro-pollutants, make traditional soil utilize the way of mud to be more and more subject to scholar and the public's query.Therefore, burn the final selection that often becomes many national lignin-sludges.Yet, because moisture percentage in sewage sludge is high, make to have to concentrate before sludge incineration and the pre-treatment such as dehydration, moreover, small sewage treatment plant often needs that the mud after concentrating, dewatering is transported to sludge incineration factory (or garbage burning factory) outward and centrally disposes, so the comprehensive cost of sludge incineration generally all maintains run at high level.
Based on primary/metazoan, catch microphagous Sludge Reduction Technologies because thering is the advantages such as economical and efficient, non-secondary pollution, caused the extensive concern of Chinese scholars.Limnodrilus hoffmeisteri is as the maximum metazoan that can observe in Sewage treatment systems, can be attached to growth and breeding on filler, there is higher anti-pollution ability and larger mud phagocytic activity, thereby be widely used in the research of mud decrement, and be considered to a kind of comparatively desirable prey organisms for mud decrement.
Traditional reactor all has obvious mud decrement effect, but it is all independent of outside Sewage treatment systems, needs peripheral hardware Limnodrilus hoffmeisteri mud decrement system in actual process, increases extra capital cost.Test shows: life habit and the active sludge aerobic biochemical condition difference of finding Limnodrilus hoffmeisteri are little, if can develop a kind of bio-reactor that can realize Limnodrilus hoffmeisteri-microbiologically stabilised symbiosis, realize the synchronous degradation effect of wastewater sludge, needn't be newly-built a large amount of independent mud decrement facilities, even Zhi Xudui sewage work existing utility is necessarily transformed, do not need newly-built treatment facility, thereby greatly reduce capital construction cost.Therefore, be necessary to develop a kind of novel reactor that can realize Limnodrilus hoffmeisteri-microbiologically stabilised symbiosis and there is the synchronous degradation effect of good wastewater sludge.
