Embodiment 1
[0031] Embodiment 1: A kind of sewage joint treatment equipment, this equipment comprises pretreatment tank 6, mixing tank 1, high-density flocculation tank 2, sedimentation tank 3 filter tank 4 and aeration tank 5 successively along the sewage treatment direction, described mixing tank 1) A water inlet pipe is provided, and an outlet pipe is provided on one side of the aeration tank 5; the water source is pumped from the center of the river to the pretreatment tank 6, and the buffer tank 6 is lifted to the mixing tank 1 by the submersible pump after pretreatment, and the mixing tank 1 It is fully mixed with the coagulant PAC through the action of the fast mixer, and then enters the high-density flocculation tank with a high-density structure, which is equipped with a frame-type stirring paddle with a guide tube inside. Circulation, fully mixed with the coagulant PAM to produce flocculent alum flowers, and then overflow into the sedimentation tank 3, the sedimentation tank 3 is...

The invention relates to an ecological filtration treatment process technology for treating water of inferior five types of rivers or water of black and odorous rivers. The invention discloses a treatment process capable of purifying surface water. On the basis of the principle of a high-density sedimentation tank, inclined tube sedimentation and physical filtration technologies are added; PAC andPAM which are added in the early stage can adsorb suspended particles in water; a link bridging effect is achieved among the particles; the fine particles form relatively large flocs; the precipitation speed is accelerated; coagulated impurities and precipitates are effectively removed through precipitation and filtration of an inclined plate sedimentation tank, SS suspended solids in water are effectively removed through filtration of fiber filter cloth of the tank body in the later period, treated clear water enters a clear water tank which is provided with a built-in aeration system, the oxygen content of effluent is greatly increased, and aeration before effluent enables the oxygen utilization rate to reach the highest.
Description
technical field [0001] The invention belongs to the field of treatment of river sewage, and in particular relates to a multi-mode joint sewage treatment technology. Background technique [0002] Today's social economy is developing rapidly, people's living standards are improving day by day, and environmental problems are becoming more and more serious. The pollution of rivers and lakes not only affects the ecological balance of water areas, but also threatens the safety of drinking water for human beings. The fundamental reason for the pollution of rivers and lakes is that the amount of pollutants contained in the water body exceeds its own water purification capacity, and the high concentration of pollutants makes the water quality of the water body continue to deteriorate. Sewage is directly discharged into rivers and lakes, which increases the difficulty of river and lake water treatment and subsequent maintenance, and the purified water quality is difficult to maintain ...
