Problems solved by technology

The incineration investment is large, the operating cost is high, and the management is complicated; the sanitary landfill has a high moisture content in the sludge, which seriously affects the landfill operation, and it is also prone to sliding and collapsing of the garbage pile in the sanitary landfill site, and the landfill site is unwilling to accept sludge; Sludge agricultural compost is restricted by heavy metals, pests, etc., making it difficult to apply

Embodiment 1

[0033] A method for making a degradable seedling pot, comprising the following steps:

[0034] (1) Mix the sludge compost product and clay evenly; the weight percentage example of sludge compost product mixed with clay is: sludge compost product 90%, clay 10%;

[0035] (2) The mixed material is pressed into shape through a mould;

[0036] (3) drying (generally natural drying), that is, the product of the seedling pot is obtained.

[0037] The sludge composting product is obtained by mixing sludge with a water conditioner and undergoing aerobic fermentation. with existing technology.

[0038] The moisture regulator can be pulverized stalks (for example: wheat straw, rice straw, corn stalk, rape stalk, reed, rattan, bamboo, herbs or other cellulose-containing materials), fly ash or / and saw sawdust. The mixing weight ratio of sludge and moisture conditioner is sludge: moisture conditioner is 1:1.2.

[0039] The aerobic fermentation process goes through three stages: medium t...

Embodiment 2

[0042] A method for making a degradable seedling pot, comprising the following steps:

[0043] (1) mix the sludge composting product and clay evenly; the weight percentage example of sludge composting product and clay mixing is: sludge composting product 75%, clay 25%;

[0044] (2) The mixed material is pressed into shape through a mould;

[0045] (3) drying (generally natural drying), that is, the product of the seedling pot is obtained.

[0046] Others are the same as in Example 1, omitted.

Embodiment 3

[0048] A method for making a degradable seedling pot, comprising the following steps:

[0049] (1) Mix the sludge compost product and clay evenly; the weight percentage example of sludge compost product mixed with clay is: sludge compost product 80%, clay 20%;

[0050] (2) The mixed material is pressed into shape through a mould;

[0051] (3) drying (generally natural drying), that is, the product of the seedling pot is obtained.

[0052] Others are the same as in Example 1, omitted.

Abstract

A method for preparing the degradable seedling-culturing bowl includes such steps as providing the mud or the mud compost as basic raw material, mixing it with adhesive, and die pressing. It can decrease the pollution of mud to environment.

Description

technical field [0001] The invention belongs to the treatment and utilization of sludge, and relates to a method for making a degradable seedling pot. It is suitable for making degradable seedling pots and flower pots by using sludge from urban sewage treatment plants or urban domestic garbage or compost products produced by sludge and garbage. Background technique [0002] In order to protect water resources, more and more urban sewage treatment plants have been built, and the amount of sludge produced in the sewage treatment process has also increased sharply. The amount of sludge produced by a secondary sewage treatment plant (the moisture content of the sludge is about 80%) accounts for about 0.05%-0.1% (weight ratio) of the total treated water. An urban sewage treatment plant must not only treat the sewage and discharge it up to standard, but also effectively treat the sludge generated in the process of sewage treatment. If the sludge is not properly treated, it will c...
