Technical field
The utility model relates to sewage disposal technology, relates in particular to a kind of diatomite Sewage treatment systems.
Background technology
The water quality characteristic of sewage is subject to the many factors impacts such as the character in city, existing water exhaust system, temperature, water resources and the level of economic development thereof.Exist the biodegradability of waste water poor, the preliminary treatment of trade effluent also adopts biochemical method often, so after treatment, staying the organic matter that enters city planting ductwork in waste water is difficult to biodegradable often, the biodegradability variation of the municipal effluent that contains a large amount of trade effluents, is unfavorable for biochemical treatment; The complicated component of waste water, may introduce the material that some are unfavorable for the objectionable impurities of microorganism growth or cause activated sludge bulking in waste water, thereby makes troubles to the operation and management of Sewage Plant; The water quality of waste water, water yield fluctuation are greatly.Therefore need a kind of anti impulsion load ability strong, the Sewage treatment systems that construction cost is low, treatment effect is high, energy consumption is low, working cost is low.
Utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of diatomite Sewage treatment systems is provided, and anti impulsion load ability is strong, diatomite medicament can recycle, diatomite total flow is few, and working cost is low, produces mud and is easy to dehydration with diatomite mud.
The utility model solves the technical scheme that its technical problem adopts: the utility model is comprised of the grating tank connecting successively, aerated grit chamber, equalizing tank, diatomaceous earth clarification tank, contact biological reaction tank, second pond, sterilization pool and discharge pond; Described equalizing tank bottom is provided with lift pump, is connected, and is provided with line mixer by pipeline with the pipe core of diatomaceous earth clarification tank on the pipeline between lift pump and pipe core, and the feeding opening of line mixer is connected with diatomite chemicals dosing plant by pipeline.
Described diatomaceous earth clarification tank bottom is provided with bucket, and bucket bottom is connected with diatomite tripping device by pipeline.
Described contact biological reaction tank bottom is provided with submerged jet aerator.
The utility model compared with prior art, there is following advantage and beneficial effect: the anti impulsion load ability of (1) diatomite processing unit is strong, treatment effect is very stable, be not vulnerable to the impact of temperature, water quality, water yield variation etc., the suitable processing that contains more toxic substance or the larger municipal effluent of impact load.(2) this Technology is advanced, and required equipment is few, and floor space is little, and technical process is simple, and convenient operation and management can realize automated operation.(3) diatomite medicament can recycle, and the consumption of diatomite medicament is few, can reach the COD clearance of 70% left and right when dosage is 50ppm left and right.(4) good than the chemical sludge of general biological sludge and other of diatomaceous dewatering, it is the mud cake of 58%～60% left and right that available centrifuging or sheet frame press worry machine to be dewatered to water ratio.
Accompanying drawing explanation
