Background technology
Settler is widely used in the various sewage treatment process as a kind of structures of removing suspension in the sewage.Can be divided into preliminary sedimentation tank and second pond according to position in its place sewage treatment process and role.The pattern of settler is a lot, and more common have flat flow, vertical-flow, radial-flow and a sloping plate deposition formula.
But in recent years, complicated along with the renewal of various sewage treatment process and sewage quality, traditional settler can not satisfy the sewage treatment process requirement, especially the first sink device that is in before the biochemical treatment unit is required to improve constantly.There is new requirement new biochemical treatment unit to water inlet, such as the biochemical treatment unit of the waste water of some high concentration the volumetric loading of water inlet is had certain requirement; Some anaerobic biological processing unit has strict demand to the dissolved oxygen of water inlet; There is certain requirement the biochemical treatment unit of some indegradable industrial effluent to the biodegradability of water inlet; Some filter tank technique has certain requirement to the suspension of water inlet, and adopts traditional sewage disposal settler to be difficult to satisfy the requirement of above-mentioned sewage treatment process.
The utility model content
The purpose of this utility model is to adopt traditional sewage disposal settler can't satisfy the problem that the biochemical treatment unit requires volumetric loading, dissolved oxygen, biodegradability and the suspension of intaking for solving, and then a kind of bioflocculation body filtering-depositing device is provided.
The utility model is to solve the problems of the technologies described above the technical scheme of taking to be: filtering-depositing device of the present utility model by pond body, a plurality of inlet valve, a plurality of flowmeter, many water inlet pipes, many discharge pipelines, a plurality of valve, many mud sampling bodys, organize water-locator, many water distributors, sloping plate deposition district, effluent weirs more, go out water channel, suspended sludge floor probe tube and self priming pump and form; Have a plurality of mud grooves on the bottom face in the body of described pond, the sidewall horizontal that one end of described many water distributors passes the pond body is set up in parallel the inside at the pond body, the other end of many water distributors is arranged on the outside of pond body, the every water distributor that is arranged on the outside, pond is connected with corresponding water inlet pipe by an inlet valve, be arranged on the every water distributor of pond external body a flowmeter is housed, be arranged on the every water distributor in the body of pond the one group of water-locator that is communicated with it is housed, water distributing pore on each water-locator upwards is provided with, described many discharge pipelines are arranged on the below of many water inlet pipes, the sidewall horizontal that one end of many discharge pipelines passes the pond body is set up in parallel the inside at the pond body, the other end of many discharge pipelines is arranged on the outside of pond body, be arranged on the every discharge pipeline of pond external body a valve and a mud probe tube are housed, the sidewall of every discharge pipeline is provided with a plurality of mudholes, described sloping plate deposition district is arranged on the inside of the pond body of water inlet pipe top, described effluent weir is arranged on the inside of the pond body of top, sloping plate deposition district, describedly go out water channel and be arranged on the effluent weir and and be communicated with it, one end of described suspended sludge layer probe tube is arranged on the below of the suspended sludge layer of body inside, pond, and the other end of suspended sludge layer probe tube is connected with self priming pump on being arranged on pond body top end face.
The utlity model has following beneficial effect: one, effect of the present utility model is equivalent to the preliminary sedimentation tank in the sewage treatment process.But it can also effectively reduce the COD load in the water except finishing the effect of removing suspension in the water efficiently, increase the biodegradability of sewage, reduce oxygen in water, and only need more a spot of coagulant even not need dosing coagulant, can reach the purpose of efficient precipitation.Two, owing to the bottom of sewage from the pond body enters, and the water distribution direction of water-locator upwards by the adjustment to upflow velocity, can form one deck suspended sludge layer in the body of pond.This dirty suspension mud layer is similar to filter course, the solid suspension in the sewage and most of colloidal substance can be held back rapidly and adsorbed, and biological flocculation can take place, so only need the very coagulant of small concentration, does not even need dosing coagulant.And the time of staying of this bioflocculation body filtering-depositing device will be longer than general preliminary sedimentation tank, and the time of staying of influent quality in the body of pond is generally about 4~6 hours.Because the time of staying is long, in the body of pond under the anaerobic condition, this suspended sludge layer can produce the aerobic-anaerobic microbe of high concentration, with insoluble hydrolysis of organic matter is dissolved matter, the material of big molecule and difficult degradation is converted into and is easy to biodegradable material, shortened the reaction time, reduced the processing energy consumption, and sludge discharging period is longer than general preliminary sedimentation tank.Mud concentrates in the mud groove, and hydrolysis is liquefied, and reaches the purpose of mud decrement.The suspended sludge layer height that records according to the moisture percentage in sewage sludge and the suspended sludge layer probe tube of suspended sludge layer probe tube collection determines when spoil disposal.
