Problems solved by technology

From its process flow and design parameters, it can be seen that the treatment process of this method is mature, the sludge is not easy to expand, and the impact load resistance is higher than that of the activated sludge method; the disadvantage is that the removal rate of nitrogen in the A section is very low, and it occupies a large area. High energy consumption, many structures, long process, need to return, large amount of sludge, large head loss, difficult to operate and manage, etc.
[0008] In short, the biochemical method in the prior art occupies a large area, the cultivation and management of bacteria are complicated, the one-time project investment is large, the operating cost is high, the energy consumption is high, and the sludge is difficult to handle, and there are problems of secondary pollution.

Embodiment Construction

[0026] The sewage passes through the grit chamber, the grille, and reaches the water collection well. The water depth of the water collection well is about 3 meters or more. Use an ordinary water pump to pump water, and add a natural composite material water treatment agent to the suction port of the water pump to treat the wastewater and natural composite water. pumped together with the agent into the pressurized oxygenation equipment about 10 meters above the top of the water collection well, such as figure 2 As shown, it consists of a liquid inlet 22, a water pipe connecting flange 23, an air passage 24, an equipment housing 25, a liquid pipeline 26, a first nozzle 27, a positioning ring 28, a liquid-gas mixing chamber 29, and a first pressure dissolution chamber 30 , the second nozzle 31, the second positioning ring 32, the second mixing chamber 33, the second pressure dissolution chamber 34, the delivery pipe 35, the delivery pipe connecting flange 36, and the connections...

Abstract

The present invention discloses a wastewater treatment method, including the following steps: a. adding natural composite material water treatment agent; b. pressurizing and aeration treatment; c. coagulating and flocculation; d. bio-degrading in aerobic aeration tank; e. sludge dewatering treatment; and f. separating dewatered sludge and recovering natural composite material water treatment agent. Said invention not only can reduce cost for treating waterwater, but also possesses high efficiency for removing various pollutants, does not produce secondary pollution and can change sludge into resource to make utilization, and can recover natural composite material water treatment agent, so that it is applicable to purification treatment of industrial wastewater and domestic wastewater.

Description

technical field [0001] The invention relates to an ecological resource waste water treatment process. Background technique [0002] In the existing industrial wastewater and domestic wastewater treatment, the applicable technologies are mainly two categories: the first is the widely used biochemical method, its main feature is to degrade the water pollutants in the wastewater by microorganisms, thereby To achieve the purpose of sewage treatment; the second is the physical and chemical method that has been promoted and applied by some countries and regions and industries. Its main treatment mechanism is to add chemicals through certain physical conditions to make wastewater into clean water. physical effect. [0003] The process flow of waste water treatment by physical and chemical method is waste water → regulating tank → adding coagulant → coagulation stirring tank → flocculation stirring tank → clarification tank → effluent, and at the same time, the sludge in the clarif...
