Embodiment Construction

[0020] figure 1 Schematic diagram of the structure of the filter composite layer provided by the present invention. Such as figure 1 As shown, the filter composite layer 2 includes a filter layer A and a reinforcement layer B. The filter layer A is pure polyester or polypropylene staple fiber spunlace non-woven fabric. The reinforcing layer B is a polyester industrial yarn interwoven net-like woven fabric or a warp knitted fabric, the reinforcing layer B is arranged inside the filter layer A, and the reinforcing layer B and the filter layer A are combined into one body through spunlace.

[0021] In this embodiment, the specific realization of the combination of the reinforcement layer B and the filter layer A is: during the fiber laying process of the spunlace non-woven production line, pre-add the polyester lining in the middle of the upper and lower layers of fiber laying. Industrial silk woven or warp knitted fabrics. In other words, the polyester industrial yarn interl...

Abstract

The invention provides a filter composite layer and a filter blocking net, and application method thereof. The composite filter layer comprises a filter layer and a reinforcement layer. The filter layer is a pure polyester or polypropylene short fiber spunlaced non-woven fabric. The reinforcement layer is a terylene industrial filament interlacing netted woven fabric or warp knitted fabric. The reinforcement layer is arranged in the filter layer. The reinforcement layer and the filter layer are combined together as one spunlaced layer. The filter composite layer and filter blocking net, and application method thereof provided by the invention can effectively clean duckweed, algae and other protist on surface of drinking water reservoir and urban river and lake, so as to avoid water pollution caused by aquatic protist and to ensure water quality safety.

Description

technical field [0001] The invention relates to a filtering structure and method, in particular to a filtering composite layer, a filtering intercepting net and an application method thereof. Background technique [0002] With the eutrophication of water bodies, algae overgrowth in rivers and lakes has spread to most urban water sources—drinking water reservoirs and urban rivers and lakes. In particular, the diatoms in the peach blossom season in March and April and the cyanobacteria and green algae in the typhoon and thunderstorm season in July and August are formed in mountain streams and gentle areas and drift into reservoirs, urban rivers and lakes with the flood. Breed and multiply in the water bodies of reservoirs and urban rivers and lakes, some of them will rot and deteriorate, forming aquatic protozoan pollution to the water bodies of reservoirs, urban rivers and lakes, causing the content of microorganisms and organic matter in the water to exceed the standard, aff...
