The structure divide into the steel structure, and flocculation, sediment, filtration go on in proper order, and the raw water takes place flocculation reaction in net flocculation area after mixing with the flocculating agent, gets into the pipe chute settling zone afterwards, and rivers pass through quartz sand filter layer after the sedimentation zone takes place the sedimentation reaction, accomplish the purification, reach water quality of water requirement. And be equipped with the backward flow district behind the filtering area of equipment, backwash and blowdown waste water pass through the pipeline and get into the backward flow district, and the backward flow district is divided into mud collection district and waste water backward flow district, and mud collection district sets up mud collection baffle and is used for the mud collection, regularly manually opens blow-down pipe row mud, and the built-in backwash pump of waste water backward flow district carries out the backward flow with backwash water, flows back to the raw water inlet pipe through the return line, gets into equipment again and handles to realize energy saving and emission reduction's purpose.

Description

Integrated integrated water purifying equipment with drainage sludge discharge recovery device

Technical Field

The utility model belongs to the water purification treatment field relates to an integrative water purification unit of integrated form that contains drainage mud discharging recovery unit.

Background

In the aspect of water purification treatment, equipment can carry out row mud and backwash through flocculation, sediment, filtration, back operation a period, and the backwash row mud all can have a large amount of waste water discharges at every turn, and the discharge is that waste water gets into the drainage row mud pond and arranges outward, and connecting line is longer between the relevant equipment, causes great waste to be not conform to national energy saving and emission reduction's call, and this kind of arrangement mode not only area is great, construction cost is high and the later stage drops into operation maintenance work inconvenience.

In view of the above situation, for meeting the social demand for energy conservation and emission reduction, the utility model discloses the personnel have done careful analytical research, provide the utility model technical scheme that can solve the problem.

Disclosure of Invention

To the deficiency of the prior art, the utility model provides an integrative water purification unit of integrated form that contains drainage mud discharging recovery unit.

The flocculation, the sedimentation, the filtration and the backflow are integrated and sequentially arranged in sequence, so that the treatment purpose is achieved, the space can be reasonably utilized, the cost is saved, and the purposes of energy conservation and emission reduction are achieved.

Raw water enters an integrated water purification device, firstly enters a water distribution area at the bottom of the device, and is uniformly distributed; then slowly enters a high-concentration flocculation area to carry out thorough coagulation reaction; then entering an inclined tube settling zone, and rapidly settling particles in water under the action of an inclined tube; the clear water at the upper layer flows into a water collecting tank from the separation area and enters a filtering area through a water outlet pipe, and the settled sludge at the lower layer is concentrated at the bottom of the device and is discharged at regular time; the water flow passes through the quartz sand filter layer and is fully contacted with the filter material for filtering, so that small particle impurities which cannot be precipitated in the precipitation zone are further removed, the purification is finished, and the requirement of the effluent quality is met. And be equipped with the backward flow district behind the filtering area of equipment, backwash and blowdown waste water pass through the pipeline and get into the backward flow district, and the backward flow district is divided into mud collection district and waste water backward flow district, and mud collection district sets up the mud collection baffle and is used for the mud collection, regularly arranges mud manually, and the built-in backwash water of waste water backward flow district pump flows back backwash water, flows back to the former water inlet pipe through the return line, gets into equipment again and handles to realize energy saving and emission reduction's purpose.

Drawings

The present invention will now be described with reference to the accompanying drawings, in which: fig. 1 is a schematic structural diagram of an embodiment of the present invention, in which the sequence numbers are described as follows: (1) the device comprises a water inlet pipe, (2) a flocculation zone, (3) a sedimentation zone, (4) a filtration zone, (5) a reflux zone, (6) a reflux pump, (7) a reflux pipeline, (8) a sludge discharge pipeline, (9) a sludge collection baffle, (10) a blow-down pipe, (11) a backwashing water inlet pipe, and (12) a water outlet pipe.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.

Raw water enters a grid flocculation area (2) through a water inlet pipe (1), flows into a sedimentation area (3) at the bottom after being subjected to flocculation treatment in the grid flocculation area, the sedimentation area (3) adopts an inclined pipe sedimentation process, the water subjected to sedimentation treatment enters a filtering area (4), and the water which meets the national requirements flows out through a water outlet pipe (12) under the filtering action of a quartz sand homogeneous filtering material in the filtering area.

Can produce mud in flocculation district (2), settling zone (3) bottom after equipment operation a period, the valve everywhere of mud pipe (8) is opened, and the mud of discharge bottom, mud flow-in backward flow district (5) accumulate in album mud baffle (9), regularly open blow-down pipe (10), discharge long-pending mud.

After the filtering area (5) operates for a period of time, the valve at the position of the water outlet pipe (12) is closed when the filtering effect cannot be expected, the valve at the position of the backwashing water inlet pipe (11) is opened, backwashing treatment is carried out on the filtering material through the backwashing pump, the backwashing sewage valve is opened and is discharged into the backflow area (5) through the sludge discharge pipeline (8), so that the cleaning purpose is achieved, the valve at the position of the sewage discharge pipe is closed after backwashing is finished, and normal water production is recovered.

When backwash wastewater accumulated in the reflux area (5) reaches the starting liquid level of the reflux pump (6), the reflux pump (6) can be started to reflux the backwash wastewater to the front end of the equipment water inlet pipe (1) through the reflux pipeline (7) and enter the equipment for continuous treatment, so that the wastewater reflux function is realized, and the purposes of energy conservation and emission reduction are achieved.
