Problems solved by technology

Sulfur-containing wastewater is toxic, corrosive, and smelly, causing great pollution to the environment, and will also have a great impact on the normal operation of wastewater treatment structures
[0005] At present, the air oxidation method is mainly used for the pretreatment of sulfur-containing industrial wastewater, but the operating cost is high, the efficiency is low, and it will also cause hydrogen sulfide pollution in the air. Although the chemical agent method and the adsorption method have low pollution and high efficiency, the agent High cost

Embodiment

[0021] Take a factory that continuously discharges phosphating wastewater with a displacement of 1 t / h as an example, and the filter size is 1.05*1.05*1.2 m 3 , select 1*1*1 m 3 The processing module, the filling rate of the filter material is 50%, and the hydraulic retention time is 0.5h.

[0022] Such as figure 2 As shown, two processing modules 1 are set in the filter tank 5, one for use and the other for standby, and they are used alternately. Between the two processing modules, there is a middle channel 6 of cement structure with a width of 2 meters, which is used for setting up a triangle hanger when workers pass through and replace filter materials. The bottom of the filter tank 5 is provided with a main water inlet pipe 7 and a distribution pipe 8 (opening at the upper end), an overflow weir 9 is provided at a distance of 1.1 m from the bottom of the top of the filter tank, and an outlet pipeline is provided outside the tank body.

[0023] The waste water enters fr...

Abstract

The invention discloses a filter material module capable of effectively removing phosphorus and sulfur in wastewater, which comprises a module. The module is characterized in that the side surfaces and the bottom surface of the module are respectively in a reticular structure, and the top is opened; the top of the module is provided with a lifting lock catch and an overflow port; the bottom of the module is provided with a water inlet; and a refuse incineration fly ash filter material is filled in the module. The module solves the problem of treatment of industrial high-concentration sulfur-containing phosphorus-containing wastewater, and recycles the refuse incineration fly ash, thereby treating waste with waste at very low treatment cost. The module is simple and easy to implement in the use process. The module can be taken out independently to replace the filter material, and thus, is very convenient for addition and replacement; and the optimum treatment system can be customized according to the actual water quality and quantity and the actual ground, so the module is small in occupied area.

Description

technical field [0001] The invention relates to the treatment of sulfur- and phosphorus-containing wastewater, in particular to a filter material module capable of effectively removing phosphorus and sulfur in wastewater. Background technique [0002] Phosphorus is a key element that promotes the excessive growth of aquatic plants and leads to eutrophication of water bodies. Phosphorus-containing wastewater in actual industrial production has a high phosphorus concentration. For example, the phosphate concentration in typical coating wastewater has reached about 100 mg / L, and the phosphate concentration in phosphate fertilizer wastewater is even higher, far exceeding the limit of biochemical treatment. . In actual production, at present, phosphorus removal agents such as quicklime and calcium chloride are mainly used to remove phosphate in water by chemical agents. [0003] The current calcium method for phosphorus removal not only has high processing costs, but also requi...
