Suspended sludge tank

Technical Field

The utility model belongs to the technical field of sewage treatment purifies relevant equipment, especially, relate to a suspension sludge jar.

Background

In the field of water treatment, precipitation and filtration are common and a wide variety of treatment processes. However, most of the traditional precipitation treatment units have low efficiency and large occupied area, and have poor precipitation effect when the settleability of suspended matters is poor; most of the traditional filtering devices utilize the interception function of the filler to filter, and meanwhile, operations such as backwashing, regeneration, replacement and the like of the filter material (filler) are required. Therefore, the traditional technology and equipment for the precipitation and filtration water treatment process have the defects of long purification process flow, large system, low purification efficiency and the like.

The treatment method of the oily sewage adopts a mixed treatment mode of a physical method and a chemical method. The perfect physical purification process at least comprises oil-water separation and filtration, wherein the oil-water separation device adopts natural sedimentation combined oil removal equipment, and the filtration device adopts walnut shells, quartz sand and a glauconite filter. In order to ensure that sewage treatment can reach the standard, a large amount of efficient demulsifying flocculant, water purifying agent, scale inhibitor, corrosion inhibitor and bactericide need to be added in the treatment process, so that the problems of high operating cost, increased generated sludge amount, increased emulsified oil and the like are caused, and certain pollution and damage to the environment and human bodies are caused.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve above problem provide a flow simple reliable, the system can be dispersed on the spot and arrange, investment and working costs are low, take up an area of less, the effectual suspension sludge jar of purifying.

In order to achieve the purpose, the invention adopts the following technical scheme: a suspended sludge tank comprises a cylinder body; the top of the cylinder body is provided with an upper vault, the middle part in the cylinder body is provided with a middle vertical pipe, the top of the middle vertical pipe is provided with an upper branch pipe supporting seat, and the upper branch pipe supporting seats are respectively connected with water collecting tanks arranged on the inner side walls of the two ends of the cylinder body through water collecting pipes; the lower part of the upper branch pipe supporting seat is provided with a filler supporting frame, and the lower part of the filler supporting frame is provided with an inner cone; the middle part is equipped with interior little awl fill in the interior awl, and the bottom of interior little awl fill is through leaking water piping connection interior awl, and the bottom of interior awl is equipped with the water inlet pipe mouth, and the water inlet pipe mouth communicates with the bottom of interior awl.

Further, the water collecting tank on one side of the inner side wall of the barrel is connected with the outer water collecting tank, and a water outlet pipe opening is formed in the bottom of the outer water collecting tank.

Furthermore, an oil discharge pipe is arranged in the cylinder, an oil collecting port is arranged at the upper part of the water collecting pipe, and the oil collecting port is connected with the oil discharge pipe.

Further, a clear water overflow pipe is arranged on the outer side of the barrel body, and a sludge discharge pipe is arranged at the bottom of the barrel body.

Further, an emptying pipe orifice is arranged at the top of the upper vault.

Furthermore, one side of the water leakage pipe is provided with a water retaining groove.

Furthermore, a filler layer is arranged on the filler support frame.

Furthermore, the outer side of the inner cone is a sludge settling chamber.

Suspension sludge tank purification principle: firstly, separating out pollutants in a dissolved state from a true solution state by adopting a chemical method to form colloidal particles or micro suspended particles with a solid phase interface; separating organic pollutants, chromaticity and the like from the sewage by selecting an efficient and economic demulsifier; then, various colloidal particles and suspended particles in the sewage are agglomerated into massive and compact flocs by adopting a microscopic physical adsorption method; then, by means of fluid mechanics principles such as rotational flow, filtering hydraulics and the like, flocs and water are quickly separated in a self-designed SPR high-turbidity sewage purification device; clear water is filtered by a compact suspended mud layer formed in the tank body, so that the level of three-stage fine treatment is achieved, and the effluent is recycled; the sludge is highly concentrated in the concentration chamber and is discharged by pressure at regular intervals, and the sludge can be directly sent into a mechanical dehydration device due to low water content and good dehydration performance, so that secondary pollution is avoided.

The suspended sludge treatment device combines the primary treatment and the tertiary fine treatment of sewage into a suspended sludge tank body, and the treatment is quickly finished in a flow of 30 minutes. It allows direct intake of high turbidity sewage with suspended matter (turbidity) up to 500 mg/l to 5000 mg/l, and the treated effluent has suspended matter lower than 3 mg/l (turbidity: < 3 NTU); the suspended sludge method only needs to consume 0.15kwh (degree) of electric power for treating one cubic meter of sewage, and is greatly lower than a traditional water treatment system and a traditional three-level fine treatment system such as micro-filtration, reverse osmosis membrane separation and the like. The effect of three-level fine treatment level can be obtained only by using the engineering investment equivalent to the conventional primary treatment and secondary biochemical treatment plants and the operation cost lower than the conventional secondary biochemical treatment, and the regeneration and the reuse of the sewage are realized.

Has the advantages that: (1) in the suspended sludge tank treating process, chemical agent is added to react with pollutant in the sewage and form solid phase interface particle, which is coagulated and flocculated into sludge.

(2) In the suspended sludge tank treatment process, coagulation and flocculation agents are added to coagulate suspended impurities in sewage into large and dense flocs which enter sludge, so materialized sludge generated by the suspended sludge tank is mainly inorganic substances, and the content of the inorganic substances generally accounts for more than 80-95% of dry substances.

(3) The suspended sludge tank has an extremely ingenious hydromechanical structural design, and the bypass flow formed by the filtering hydromechanical principle ensures that the sludge concentration chamber has a good sludge concentration effect; meanwhile, pressure sludge discharge is carried out periodically by the pressure of water, so that sewage cannot be discharged together with the sludge in a mixed manner; therefore, the water content of the sludge discharged from the sludge discharge port of the suspended sludge tank can generally reach below 95 percent, so that the volume is relatively small, and the workload of subsequent sludge dewatering is small. Therefore, the total workload of disposing the sludge generated by the suspended sludge tank is not large, and breaks through the old concept of large workload of sludge treatment of the physical chemical method system.

(4) The sewage purification flocculating agent selected by the suspended sludge tank is also a good sludge dewatering filter aid, so that the sludge finally discharged by the system has good dewatering performance, and in addition, a small amount of sludge treatment filter aid is added to directly pump into a filter press for dewatering.

(5) The suspended sludge tank has simple and reliable working process, low investment and operation cost, small occupied area and good purification effect, and the system can be dispersedly arranged on site.
