[0002] Chemical wastewater refers to the wastewater produced in the process of producing products in chemical factories. After biochemical treatment, it can generally meet the discharge standard. Due to the shortage of water resources, the water that meets the discharge standard needs to be further treated to meet industrial water replenishment. The required recycling, because the impurities in the water are mainly suspended particles and fine hair fibers, the impurities are removed by using the principle of mechanical filtration and microporous filtration technology; the existing chemical sewage filtration devices have certain disadvantages in the process of use, and the filtration produced Dirt is discharged through the sewage pipe. Long-term use can easily lead to blockage of the sewage pipe and make it difficult to clean, resulting in the equipment not working normally. If the internal dirt of the cleaned water is not cleaned, the filtered water will be polluted again. To improve the functionality of the chemical sewage filter device, we design a chemical sewage filter device

[0026]The second embodiment: a chemical sewage filtration device, comprising: a support mechanism, the support mechanism includes a sewage filter bucket 1 and a sewage inlet pipe 3, the upper end of the sewage filter bucket 1 is provided with a bucket cover 5, the sewage filter The lower end of the barrel 1 is provided with a detachable sewage pipe 10 and three sets of brackets 2, and a casing 11 is movably installed on the detachable sewage pipe 10, and a threaded ring 12 is provided at the position of the detachable sewage pipe 10 close to the casing 11. , and the detachable sewage pipe 10 is movably installed with a valve 13 at the position near the lower end, the sewage filter barrel 1 is fixedly installed with a positive flushing water pipe 7 near the upper end, and the sewage filtering barrel 1 is located at the position below the positive flushing water pipe 7 A clean water discharge pipe 9 is provided at the place, and a No. 2 flow meter 8 is provided on the clean water...

no. 3 approach

[0035] The third embodiment: a chemical sewage filtration method, a rotatable filter element 14 is fixed and suspended in the sewage filter barrel 1, and the water inlet speed and water outlet speed on the sewage filter barrel 1 are monitored and set, so as to control their volume. In this process, the filter element 14 is driven by the motor to alternately work in two working modes of variable acceleration and smooth rotation, and the duration of the variable acceleration rotation period is much shorter than the duration of the smooth rotation period. The sewage filter bucket 1 The bottom of the barrel adopts two detachable trapezoidal inner bottoms 16 and 17 with built-in filter cotton and oppositely arranged to form a sewage outlet, and at the same time complete the secondary absorption and filtration of sewage;

[0036] Finally, carry out the positive flushing of the filter element, turn off the motor, stop the rotation of the filter element 14, stop injecting sewage, only ...

Abstract

The invention discloses a chemical sewage filtering method. A rotatable filter element is fixedly suspended in a barrel body of a sewage filter barrel, the water inlet speed and the water outlet speedof the sewage filter barrel are monitored and set, so that the volume flow of inlet water and outlet water can be controlled, and the best combination values can be reached. In the process, a motor drives the filter element to work in turns in two working modes including vary acceleration and stable rotation, the rotation cycle length of varying rotation is far smaller than that of stable rotation, two pieces of inner filter cotton are adopted at the bottom of the barrel body of the sewage filter barrel, detachable trapezoid inner bottoms arranged oppositely form a drain port, and secondary absorption and filtration of sewage are finished. The method has the benefits as follows: the chemical sewage filtering device adopts a support mechanism and a filter mechanism, cleaning of a drain pipe is facilitated, filtered dirt can be prevented from blocking the drain pipe, purified water can be prevented from being polluted again, thoroughness of sewage tretament can be guaranteed, and the device is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the field of sewage filtration, in particular to a chemical sewage filtration device and a filtration method. Background technique [0002] Chemical wastewater refers to the wastewater produced in the production process of chemical plants. After biochemical treatment, it can generally meet the discharge standard. Now due to the shortage of water resources, the water that meets the discharge standard needs to be further advanced after further advanced treatment. The required recycling, because the impurities in the water are mainly suspended particles and fine wool fibers, the impurities are removed by using the principle of mechanical filtration and the use of microporous filtration technology; the existing chemical sewage filtration device has certain drawbacks in the process of use. Dirt is discharged through the sewage pipe. Long-term use can easily lead to blockage of the sewage pipe, which is difficult to clean, resulting ...
