Dirt treating agent and application thereof

Abstract

The invention provides a dirt treating agent, comprising a first component including modified water-absorbing resin; a second component including dextrin, hydroxypropyl methyl cellulose and polyvinylalcohol; and a third component including ferrous sulfate and quick lime. The modified water-absorbing resin is acrylic water-absorbing resin treated with a surface crosslinker. The mass ratio of the first component, the second component and the third component is (3-4):(4-6):(0.5-1.5). The dirt treating agent provided herein is capable of quickly dewatering and solidifying the covering dirt, and is rarely cracked or dispersed after absorbing water, the water-absorbing resin can be recycled conveniently after using, resource waste is reduced, and manufacturing cost is lowered; the dirt treatingagent has good desulfurizing, bacterial removal and harmless dirt treatment effects, is applicable to trash stations, sewers, septic tanks and other large-sized dirt gathering sites, and helps reducethe damage to the nature and human health due to dirt.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment agent and application thereof, in particular to a sewage treatment agent for treating garbage, sewage sludge and fecal excrement and application thereof. Background technique [0002] With the development of the economy, the population continues to grow, and the discharge of daily garbage, sewage sludge, fecal excrement, etc. has also risen sharply. In densely populated urban areas, the disposal of sewage is relatively timely, but requires a lot of manpower, and there are a lot of liquid garbage in the garbage station. These garbage have unpleasant odors and are difficult to handle, causing great difficulties to sanitation workers. However, in sparsely populated rural areas, remote areas, or areas affected by natural disasters that need rescue, due to limited conditions, the disposal of sewage is not timely. It will also release toxic substances such as hydroge...

AI Technical Summary

Problems solved by technology

But the following problems still exist in existing dirt treatment agent: (1) the granular dirt treatment agent with cellulose as binding agent disintegrates into powder very easily after absorbing water, makes the recovery of superabsorbent resin very difficult, Cause a lot of waste of resources; (2) Mainly focus on its water absorption and deodorization performance, but less attention is paid to the desulfurization, sterilization and harmless treatment of sewage, and the effect is not ideal

The treatment agent is easy to disintegrate into powder after absorbing water, so the patent puts it in a bag for a small amount of feces treatment. The water absorption effect is average and it is not easy to recycle, so it is not suitable

[0005] Zhang Liangpei and others studied the effect of surface crosslinking on the water absorption performance of superabsorbent resins and found that the water absorption resin obtained after using formaldehyde as a surface crosslinking agent has a fast water absorption speed and good water absorption performance. After water absorption, the surface of the gel is dry and easy to disperse after entering water. No agglomeration (Zhang Liangpei, Zhang Weiying, Li Xiao, etc., Effect of surface crosslinking on the water absorption performance of superabsorbent resin, Functional Materials, 2012, 5(43):653-656), therefore, the water-absorbing surface crosslinked by formaldehyde alone Resins are not suitable for practical sewage treatment
