Embodiment Construction

[0038] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0039] A method for improving coagulation, sedimentation and filtration effects in water purification treatment, the method is realized through the following steps:

[0040] Step 1, adding the raw water of the polyaluminum chloride PAC coagulant with an alumina content of 30% enters through the pipeline mixer and enters from the water inlet pipe (1) in the middle of the integrated process reactor, the polyaluminum chloride PAC coagulant The dosage is 5.0-25.0 mg per liter of raw water;

[0041] Step 2, the raw water in the water pipe (1) described in step 1 passes through the circular water inlet baffle system (3) fixed on the top of the pool and enters the first vortex reaction chamber (2) evenly from top to bottom;

[0042] Step 3, the water flow is mixed uniformly through the small hole vortex reactor (4) placed in t...

Abstract

The invention provides a method for improving coagulating sedimentation and filtration effects in water purification treatment. According to the method, the ubiquitous deficiencies of relatively poor flocculation and precipitate purification effects, poor shock resistance load and relatively high energy consumption of a settling pond are solved. According to the technical scheme, a first eddy reaction chamber, a second grid reaction chamber and a third eddy reaction chamber form a flocculation reaction unit; different types of eddy current flocculation reactors are respectively arranged in the first eddy reaction chamber and the third eddy reaction chamber; different types of grid flocculation reactors are arranged in the second grid reaction chamber; an inclined tube precipitation reactor capable of improving the separation effect is arranged in a clarifying separation chamber; a rapid filtering unit device, homogenized filter materials and a short-handle filter head are arranged in an annular efficient tank, and meanwhile, the annular efficient tank is provided with a back-flush system; and a sludge concentration unit is additionally arranged at the bottom of a tank body, so that the pressure of a subsequent sludge treatment facility is relieved.

Description

[0001] Technical field: [0002] The invention belongs to the field of environmental protection, and relates to an integrated technology for improving coagulation reaction effect, sedimentation efficiency and filtration effect in water treatment, which is based on micro-vortex and grid cooperative flocculation, shallow pool theory and rapid filtration mechanism And put forward. [0003] Background technique: [0004] The clarification process is one of the main methods of water purification treatment today. It integrates mixing, reaction and precipitation processes to remove more than 90% of suspended and colloidal impurities in water. [0005] The traditional clarification process has two major disadvantages: First, the sludge circulation type water and sludge have sufficient contact time, but because the water and sludge move together, there are few contact opportunities, and the sludge suspension type water and sludge are relatively There are many chances of collision, but ...
